Your an honest good old fashioned mechanic not to many of you guys left you actually remind me of my Uncle Rudy he was a diesel mechanic for many years in Arizona on what they call a Truck farm there
I had Ford replace both my diff fluids (and every other fluid) at 30,000 miles to give it a flush after a good break in period. Then I replaced the fluids with Amsoil another 30,000 miles after that. 13 years of pulling a trailer later my diffs are still as quiet as the day they were new. I don’t know if that’s due to the maintenance but it certainly didn’t hurt it any, I’m happy spending a few bucks keeping fluids changed rather than paying for untimely repairs later.
Unfortunately it isn't a maintenance issue, most technicians are undertrained in differential/pinion preload. It's really a big deal! You can find some very interesting stories about brand new vehicles (out of the factories) with mysterious unsolvable noise from the rear axle...
The rotational torque of that pinion gear has to be around 20in/lbs for a brand new arrangement, less than that it's noisy or could be misaligned under load resulting what we see on the video, more than that you significantly reduce the bearing lifespan.
Look that up it's good stuff if you're interested.
He mentioned it in the vidjya. It's not the fluids; it's how they set it up at the factory. (But please keep changing your fluids, which you are doing a good job on. 👍)
@@romainberger This was totally a maintenance issue. The pinion bearing was pitted from rust. The bearing was not fatiguing from too much pressure and flaking off. The fluid had moisture and/or the truck (still has a new smell) sits and had condensate that pitted out the bearing. Fluid changes at 10, 30, and 60k would have prevented this repair.
People always making excuses for ford's incompetence.
Why doesn’t Toyota have the same problem…they are mass produced….WTFO.
You are one of my favorite YT content creators. Every video is absolutely professional to a 'T'. I wish you were my mechanic. Please keep up the phenomenal work you do! 🤩👍
Dude you’re a Gem! Now i know the problem to my ford after so many videos. More people like you is what we need
Best mechanic on RUclips hands down. 😎
I am with the other people’s posts, you are one of the most knowledgeable mechanics out there!
I always enjoy your videos! I have a ‘05 F350 SRW 6.0L but trucks are trucks and somethings are the same.
Thanks for all you do making your videos and look forward to seeing your next video!
I've heard a lot of bad stories about the 6.0L -- make sure you are learning about that engine and what it takes to make it bullet proof.
@@calholli its because people dont maintain them. and they throw a punch of power on it and skip out on the basics.
I really appreciate when you have the opportunity to let us hear things that are bad, you let us hear it too! When my transfer case was going I would hear humming when I gave it gas and it would stop when I let off the gas!
I can't tell you how badly I wished I lived closer to you! Thank you for all the videos, you have saved me countless hours and $$ maintaining my 2010 F150!
I have a 2011 F-150 with 179K miles and just had the leaking rear seal replaced ($ouch$$)! Have you had any problems with yours?
You are amazing Brian. I had a 78 Mustang Cobra (cough Pinto) years ago that developed a brg noise. After a week or so of using all the clues I could get I thought it has to be the rear output brg in the trans so I went and bought a new one before I even pulled the trans. Sure enough there were visible rough spots in the outer race. Changed it put it all back together and all was good.
My next door neighbor at the time was a metallurgist at Chrysler's headquarters and ask me to give him the brg to analyze. A few days later he brought me a piece of the brg embedded in sort of plastic where they had highly polished a cross sectional cut of it. He said they had looked at it under high magnification (maybe electron microscope) and decided that there had been contaminates in the steel when the brg was made. I wonder why they don't put a magnet in differentials like they do in transmissions and other things.
Oh how I wish I was young again.

Awesome content Brian! Not only are you a crack shot technician, but your camera & sound ability is just as good!👍 thank you for all your videos , keep them coming sir!
Man I’d be lost without you. For the longest time I was convinced the noise was my front wheel bearing but it passed every test and I was ready to pull my hair out trying to figure this out.
I replaced TWO NEW wheel hub assembly ( bearing) , noise still there 😂😢🎉❤😅😊
@@tkrdg7885 I ended up just replacing the IWE since it was a cheaper part and it fixed it. It hasn’t made a noise in 6 months.
@@kennethdrury4993IWE?
Great info. Got a similar noise on a 97 Expedition with 219k miles. Suspect this is the issue as well. Great content as always.
I appreciate how you take us along for the diagnostic test drive
I began hearing this on my 05 F-150 a couple months ago. Brought it to my local shop and they said they couldn't hear it but I know my truck and the noises it makes. I gotta bring it back and send them a link to this video. Thanks for this mista
You sir are a godsend! Been racking my brain on this for a few months. I was thinking I was having some kinda bearing noise. But it' not persistent with the rolling of the truck. Its exactly as you describe it from 1:33 to 1:50. Same truck. 06 FX4 102k miles. Now I know what I'm opening up in the morning.
Another great video. I have built the old 8" and 9" but not anything newer. Great work
Thanks again. Always appreciate your videos. Have a F150 With 240K Miles still going strong and driving smooth. Running into the odd issue as every vehicle but this thing keeps going. Thankfully have the 6.2L
You are an honest mechanic, 3 shops told me I need a rebuild $2500 to $3500. Afywr watching several.of these vids, my guess is 5 hrs to R and R the pinion? Even ar 7 hours, at 185$ an hr...anyhow, we need more honest guys like you!
Wish I lived by your, amazing how knowledgeable you are. 👍
I’ve got an 06 Ford F-150 Lariat at 215k and I’m having rear pinion bearing and seals replaced as we speak. Funny thing is, I started your video here and my mechanic called and confirmed it lol.. love all your work brother 🤙🏽 definitely learned a lot from all you share 💯👌🏽
Have a fairly quiet whining noise from the rear of our 05 F150. Has stayed the same the last year and a half. But you can definitely hear it. Obviously not sure what the cause is. Have 267k on the truck now.
On another note had a P0345 code, CEL was on. I know you say the sensor never goes bad but I took the chance anyways because of the mileage on the truck. The sensor did fix it. But so thankful for this channel.
Yup bearings worn out, I always try and stuff 3 full qts in a 9.75 and never had one fail yet. As usual, nice job Brian!!
Excellent expose. Great videography and narration. Always a please to watch!
Good instructional video on what constitutes and differentiates bearing noise from gear noise.
Good work Brian. It's quiet and rolling easy.
That was your truck?
My brother lives on the east coast. He took his truck('17 F150 w/80k miles) to several dealers and they all told him his trans was going out. All with hefty fix cost. It had the so-called dreaded trans hone. He had to come to okla to get his trailer/car. He said he thought he was going to break down before he got here. I took a ride and within 1/2 mile I told him it wasn't his trans. It was his axle. He looked at me dumbfounded. He borrowed a vehicle and left his here for me to fix.
I pulled it apart. All carrier and pinion bearings were ate up. A lot worse than the one in your video. The hard part was finding a bearing kit for the super 8.8. Oreillys, advance, autozone didn't have anything to fit it. I literally ordered every kit listed for several years, axle sizes, engine sizes, etc and no luck. The pdc told me the bearings were back ordered.
I ended up buying a set from national drivetrain out of all places on ebay, (83-1047-1) which ended up being a Richmond set for $219.52. I just wonder why no one could look up the part number. Even summit & jegs(at the time) didn't show the number on the box.
I finally got the bearings all installed. The Richmond set had the original koyo bearings in it, so every spacer was right on. The crush sleeve was the headache. It didn't matter what I did, it wouldn't crush. 3/4" 4ft bar with yoke lock wouldn't crush it down. 1200 lbft impact no luck. Nothing I tried worked. I took it apart a couple times to make sure everything was in correctly. I know it's not right, but I had to disassemble and install the original crush sleeve. It went right in and I tightened it up till it had the correct drag. No slack and seemed to work fine.
Got it back together and works like a charm. I've been driving it for a few weeks now and the only thing I notice is the gears are whining a little right between drive and coast. So little I'm the only one that hears it. I'm assuming since he drove it so long, many thousands of miles with the bearings tore up that it wore the gears and the only way to fix it is replace them. I'm not an axle expert but I've prob did a couple dozen in my time. He's def glad it was under $300 to do the bearings with oil and not the over $4k the dealer was quoting for a trans.
I wanted to mention also that he hauls a ton of weight. He maxes out the rated capacity with his huge rv. He has airbags that get 85psi to support the rear and weight distributing equipment. He should've got a gooseneck and not a bumper pull. But he carries his dirt bikes in the bed. And if he didn't have a lead foot, it would prob help.
Thanks for taking the time to post the video. Great visual, I really couldn't hear the noise on the before shot but having the visual was great.
Oh it was very clear.
@@FordTechMakuloco My ears are getting bad these days. Worked next to conveyors all day for years and years. Like the old timers I knew when I was a kid, listening can be a great tool.
Excellent and probably the best videos out there!
Literally just got mine fixed after hearing it for almost a year and wheeling hard. Kept looking through your channel for some more diagnostic clips but knew it was more than likely the rear end. Shop said mine were bad (metal on metal inner and outer bearings), just glad I left it to the pros. All seals and bearing replaced. She's quiet now and feels like less resistance when coasting or driving.
how much did it run you?
@@treyhoagland8830 funny how it’s not a known repair cost… I spoke to two different shops, one went MIA but said btwn $1100-$1700. I went with another shop whose quote was less and were responsive (mainly work on race cars). All seals and bearings for a 9.75 rear end on my Raptor was $800, glad those other clowns stopped responding. She’s quiet and all I hear is the engine and probably a manifold leak now.
@@LPerez gotcha, thanks
Nice work is always Brian thank you...
Again Good info Brian.
Took my 06 F150 Lariat 5.4 2 WD to a independent shop for whining/roaring you so accurately described. I'm anticipating the bearings you described to need replacing. Ford dealers estimate was $3850 which includes ring gear I think. Wish I could figure a way to send you a copy of the estimate. I spoke to you few days ago about another issue. The 45 mph low rpm up hill climb producing misfiring under load. The independent shop going to replace all 8 plugs with Motorcraft plugs and test coil resistance. Intake cleaner run thru and drive hot
1400 to 1600 for differential rebuild provided gears are ok
500 to 600 for R/R 8 MOTORCRAFT PLUGS , test coils and intake cleaner. Provided nothing crazy occurs. He said he has good luck with the intake cleaner and driving hot before plug replacement reducing chances of plugs breaking.
So
1600 + 600= $2200 provided gears ok
Praying for good success by next week. Lol
I have a 2011 F150 with 57K miles that is making that terrible noise. I'm confident that you just showed me my problem with my truck. Thank you!
Another satisfied customer ………. For life !
Well Done !
Great stuff as usual Brian, Thanks!
Awesome content Brian as usual. I’m with everyone else I wish I lived closer so I’d know I was dealing with the most honest Tech on the planet!!
Another great video, Brian. Thanks for it. I had an 03 Town Car with a rumbling noise and I thought it was badly worn tires. Well, after installing a new set of tires, the sound didn't change at all! Took out the axles, as there was an issue with improper hardening of the axle surfaces and sure enough, the surface looked like this one. All flaking off. New axles and bearings later and the noise went away completely. Apparently, the hardening process was done incorrectly, or the metal itself was bad. Funny thing, the bearings looked fine, just the axles were flaking.
There was actually a recall for that issue.
Wow
What did your noise sound like? I’m considering buying a car that might have this issue but I’m scared the whole rear is bad as opposed to just an axle bearing (seems too easy 😅)
Interesting stuff Brian thanks for passing the info on...
I just received an email from Ford Authority that featured this video in it. Brian rocks!
Nice!
Would love to see the reassembly of this.
Recently I replaced the transaxle fluid in my 2018 Explorer 27,000 miles. It doesn’t call for a fluid change until 60,000 miles but I wasn’t happy with the way it was shifting up/down. I was surprised how dark the fluid was, though it was not burnt, it felt thick and didn’t have a good smell to it. Used a good quality trans fluid and nothing else. Car shifts smoothly now up and down. I’ll probably do this every 25,000 miles from now on. In contrast, the engine oil was very clean, had good body and smell.
Thanks Brian great video.
Beautifull ! thank you Brian. As allways you are precise and clear and the videos are of top quality.
I have exactlly the same problem on my 2008 F150
I have a couple of questions :
- Apart from the metal shavings from the bearings, do the pitting of the bearings can afect the gears by altering the tolerances ?
- How much a job like this one, would roughly cost ?
Damn I wish I could get my 2000 f150 to u brother!! Bc not many trustworthy mechanics left in this world! But you seem to be the best I seen so far and you're 750 miles away from me ! And I want to bring my truck to u so bad that it's not even funny !! My hat is off to u my friend!!
Great video and what looks to be a very nice truck! Except for the diff!
Great video- every time I watch I learn something. :)
Would love to see a rear differential rebuild. Watched one from robinsonauto that was pretty good but I never feel 100% without a FT video

yes, it is often the trip worth to get things done right the first time.👍
I am fortunate to live 75 miles from Brian's shop. I can tell you that it is worth the drive. He has mentioned in previous videos, customers even coming from Texas.
Awesome video as usual!
Thank you for your videos 👍
I have a 2014 5.0 with 60k miles and had differential work around 45k miles in 2019, and now the noise is back. Good times!
For years I took my 06 F150 to multiple Ford dealer shops telling them the rear end had problems and was getting loud. Even when it started howling they'd say there was no problem. Eventually I ended up in Junction City, KS for a few weeks and took it to the Ford dealer there. They immediately called me about the horrific prehistoric monster noise it was making...I explained that yes, that is what I was needing addressed. They were amazed that anyone would say there was no problem...there was extreme damage to the gears, races and bearings...it was a $3,000 repair. Now this summer the noise is starting again.
Damn! Great video! That’s exactly what mine is doing and now I know what it is thanks to you
Great video diagnostics 👍🏼
Wow new favorite car channel
great video,Thanks for posting.
Previous owner of a 2004 F150, brought it in for a complaint of vibration/groaning when turning u turns from the rear end. Only had like 80-90K. Needed LSD rebuilt, new carrier and pinion bearings, and seals. Fortunately the warranty covered it. I was surprised because I have known the 8.8 and 10.25-10.5 sterling to be excellent axles.
Geez, talk about a perfectly timed video. I have been trying to figure out for the last month here, if I have a bad wheel hub, bad tires, or this! I'm pretty certain my my rear differential bearing is failing. You are an incredible resource for us F150 owners Brian, thank you again!
Finally got around to working on my differential. The right side carrier bearing race had a small amount of pitting. I replaced all of the bearings including the outer axle bearings, what a PITA! No more rear differential noises! There were a lot of gotchas along the way performing this job, but so far so good!
Great Channel.
That really looks like it was a bad bearing from the bearing factory...or the diff got moisture in the case and wasn't driven for a while. Either way, great video...as always.
I have been seeing failures like this recently on the newer 12th and 13th generation f150’s. 99% of the failures I’ve seen have all recently had their differential fluid changed. Now I cannot confirm if they are putting in the wrong weight oil, but I never seem to see failures with people who don’t service their differentials. I’m no saying don’t change your diff fluid, but I’ve seen trucks with well over 200k miles on the differential and requested a differential fluid change and all the bearings looked amazing.
Awesome videos thank you
I love it when I can actually see the wear on the bearing, if you can't see it you might be able to feel it rolling it with your fingers and feel the grit.
Excellent work Brian. Imagine how many parts changers would pull that whole axle with the nice gears and put a used salvage yard special in. and probably charge more.. to get less.
That was like a punch in the gut reading that lol never again
It always is some specific thing it’s never wise to just get the junkyard replacement that is worse quality overall, older, been exposed to weather, probably not even original size or year lol
So true
Great video
HE IS TELLING THIS CORRECT (I PERSONALLY CHANGE MY DIFF FLUID EVERY 2 YEARS,AND USE 75/140)9.75 IS A WEAK LINK ON THE 150.JUST WHAT I DO HOPE THIS HELPS YALL
Great Info. Thanks
I bought a very-very used 2001 F150 265k because I knew Brian would have a repair/advise for every prob these trucks have. So far, things are getting repaired before anything goes boom. Right now I'm trying to find the source of a whine noise HW driving also a grumble grumble when turning from a stop.
I always look forward to your vids , just in case you have a vid on the 2015 GT 5.0 engine.
Great vid as usual! I'm having this issue on my 2005 ford expedition. How much should I expect to pay for this repair? Thanks for your help!
On my 95 F150.. the carrier actually cracked all the way across one half side-- (and I mean completely broken into two pieces and separated.. Somehow it still held together and drove, but it was talking like pac-man and popping and chattering like crazy under load around corners. I just swapped my ring gear onto another cheap used carrier and used the same shims and it worked out great. That truck went to 320k miles, and then it finally spun a bearing. It was a long bed/ extended cab 5spd manual, but with only the 302 engine-- so it was too much truck for such a small engine; and I towed a lot with it. Was still a monster in 4 LOW though.
I have also found CASTING SAND inside the hub between the bearings that gets ground up in the grease.
love your vids
I'm all too familiar with that damn noise. I changed mine three months ago. My '04 has 198000 miles, so really no complaints.
My 2016 just had this problem. Good thing I had the extended warranty. My front diff had a bad bearing too.
Like obviously I have to watch specialized videos recorded on a flip phone for certain odd repairs that are super specific but in general as a ford owner this looks like my new fav channel for a non autistic mechanic breakdown of these issues and parts etc
I had a brand new 1998 F-150 with a whining sound from the rear axle. For some reason the noise occurred at about 30 mph and then again at 70 mph. The dealer adjusted the tolerances in the differential, which did not correct the problem. Then they replaced the entire rear axle with a new one from the factory. This did not correct the problem either and they said it might be a design or manufacturing issue. The dealer gave me an extended warranty on the axle. The noise gradually went away, and I traded it at 43,000 miles.
This channel is the best advertisement for Toyota
Those things have been beat with the UGLY stick. and no more V8? eff them.
Great video as always, but I would like to have seen you show exactly how your tore down, replaced/rebuilt, then put back together the rear differential. Especially pointing out areas were you could make a mistake.
I have a video about that too. I just need to edit it.
@@FordTechMakuloco Did you go ahead and replace all of the bearings and races since you had the differential apart?
yes
@@FordTechMakuloco can't wait to see that video along with where to get parts.
@@FordTechMakuloco can't wait! My 07 has this same noise and I've been trying to diagnose it for months now with no success.
Thanks!
I had the exact same thing happen on my 2006 Lincoln Mark LT at about 113,000 miles.The pinion bearings were shot but everything else was perfect.
It makes sense for the bearing race to have heavy wear in one corner. The gear mesh will load the bearing more in a particular spot due to the separation force of the gear mesh.
I have a 1998 Silverado that I bought new and at around 55,000 miles, I started to hear what I thought was some rear end noise. At around 75,000 miles it was really loud so I took it in and the pinion and carrier bearings were shot. I had replaced the diff fluid at 30,000 with Mobil 1 synthetic gear lube. The shop told me to not use synthetic in that rear end and I'm now at 142,000 miles with no noise. He used conventional fluid in it.
I had hardly ever hauled or towed anything with this truck and was surprised that I had problems that early.
I replaced the fluid in the rear of my 14 Musang GT at around 3,500 miles when I installed the Ford Racing aluminum diff cover and that fluid was totally nasty. Grey with tons of metal particles from what I assume was break in. I'm at 34,000 miles now and may replace it again in a few thousand miles.
Another great, informative video👍 Thanks for sharing your expertise.
Must be the production lines at that time cause my rear in my 95 f150 just went up. Thanks for the video
I wish I lived near your shop. My 05 F 150 with 190k miles (maintained by the book by the dealer, looks like new) had a slight pinion seal drip. Brought it to the dealer - diff fluid was still close to full. The dealer replaced the pinion seal. It seemed to have a very very slight whine, and within 1,000 miles of the repair, the diff is roaring. They have told me that my differential must have already been going out, but, I am betting they did the work wrong. It upsets me becase it was silent prior to this repair and was just as quiet as when it was a new. truck.
Normally I look up videos when I have a problem. But you sir. I watch for fun.
I have a 2007 Mercury Grand Marquis that's making the same noise. Those Ford axles can be hit or miss. Kinda like marriage 😂
Thanks for the info. I feel more educated dealing with the shop now that I've seen your video
Great timing for this video as I just had the rear diff in my 2018 F150 rebuilt. Can you briefly advise on proper break-in procedures... my dealer didn't go over that part when I got my truck back, which I imagine is pretty darned important.
Thanks!
Asked specifically about this at dealership and they said no break in needed. Just like getting into a new vehicle. Not sure if I’m entirely convinced though… not a lot of confidence in that answer though. Guess it depends on how long you’re going to love your vehicle for.
Great video, I would like to have seen you set up the rear axle
I will soon
Looking at the front pinion race and roller wear, I would suspect an out of round bore more tan anything else as the rear pinion race and roller appeared normal for the mileage. Always enjoy your videos very much!
Your saying the pinion bearing wasn’t the main thing causing the noise??
@@Khlandestine I should have been more explicit as I reread my comment and see what you’re saying. The front pinion bearing was definitely making the rumbling noise imo, but the slight howling noise was coming from the slight loss of proper pinion/ring gear alignment because the front pinion bearing and race were excessively loose allowing the misalignment of the pinion and ring gear thus the noise. I also thought (from what I could see in the video) that the pattern on the ring gear was nice and smooth, but you can see the pattern was from the toe all the way to the heal of the teeth and a proper pattern would be from the toe 2/3’s to 3/4’ of a contact pattern up the teeth starting at the toe unless it had extreme mileage and it looked like a newer truck. My wife’s suv did this exact same thing and we were the original owners. When I tore it down it took me awhile to figure it out. Front pinion bearing looked like this one for no apparent reason until I measured the race bore with a micrometer and found to be .005” out of round. Took 60,000 miles to rear it’s ugly head. Also on inspection of the carrier housing, you could see a definite scar indicating it was probably dropped sometime during the assembly process. The front bearing is furthest away from the pinion gear so any slight movement (torque) will cause misalignment between the to gears thus the slight howling noise along with the growl sound. Sorry to be so wordy and it’s just my opinion from my personal experience and being a mechanic by trade for 45 years +. P.S. if you read my entire comment sir, you’re a very patient person.
Got to 214k on my '03 F150 4x Lariat. Nearly $6k for a remanned rear axle installed. Truck's served its purpose and with today's crazy prices and stupidly high interest rates, worth every penny to have a replacement put in.
Reg diff fluid changes plus Lucas added has served me well, what's your opinion? If you get that fluid to cling to the bearing that's the trick.
I have a similar problem with my 2015, eco boost, 3.5 157 wheel base, 137,500 km. 9.75 rear end. Severe vibration at around 95 to 110 km when I let of the gas. It’s loud and can really feel the vibration thru steering wheel. Its got new tires and wheel alignment, balance etc. This video Brian shows me what the cause might be. Can you give me an idea of the man’s hours to perform the repair you showed us. That’s from Edmonton, Alberta, Canada.
Lol I know that exact junction! Near Bristol. Thought I recognized that property near the end of video
Yup. Exact thing happened with my 2017 F-150 STX @ 60,000. I work construction and tow and haul a lot.
Not cheap to repair.
How much just to replace pinion bearings?
Impressive! Thank you so much for your knowledge. Can you tell me, on the whole, how long did it take you to break it down and put it back together?
Oh at least 6 hours.
Thanks for the video, Brian. In need of your help. I have a 2009ford f150. Rear axle seems normal, but in 4 high or 4 low in reverse there's a loud noise from the axle. Any thoughts about this is appreciated. Thank you. Enjoy your videos and knowledge you have on Ford vehicles. Any opinions from any other veiwer is welcomed.
good video would have liked to see you set the lash and put it back together
