F100 8.8 rearend swap and Backyard Customz (BYC) C notch
HTML-код
- Опубликовано: 29 сен 2024
- In this video I pull the original Ford 9 inch out and replace it with a Ford Explorer 8.8 rear end with disc brakes, 3.73, and limited slip. I also install a Backyard Customz (BYC) mini c-notch kit in the bumpside F100. I run into some trouble at the end with the offset of the wheels not clearing the bed.
Backyard Customz Mini C notch kit used in this video: (ebay)

I don't get all the negative comments and replies. Don't chop up the truck? It's his truck and this is America last time I checked. I have chopped mine to pieces and put it back together and it is better than it ever was. As far as the 8.8 and CV swap, did that too and the truck could put out 600hp and never blow the rear, it can't get the traction it needs to hold that power. A CV swap is a no-brainer and the 8.8 fits perfectly with it. I also just did a C-Notch in mine. When it gets that low, the axle will hit the frame if it isn't notched and the suspension travel is needed for safe operation.
hahahaha thanks for the encouragement!
@@330_garage3 you're doing a badass job and I'm enjoying your content. You're ahead of me in your build and can enjoy your truck. I spent months just doing rust repair. Now I'm spending a fortune on mechanical stuff and putting back together.
To each his own, but lowering it to the point of notching the frame, not what I would do.
so a junkyard has a black friday sale? did they call it greasy friday? either way good pick up..pun not intended
hahaha yeah Pick N Pull does sale days usually around the federal holidays. 40 - 50% off everything you can haul out of the yard!
Idk why everyone's freaking out about the 8.8 over the 9. Clearly there are benefits for having the 8.8. As for hacking up the frame he obviously wants the truck to sit lower and there's no way to do that without notching it so even if he didn't replace the 9 he'd still have to c notch his frame regardless. Sometimes 3" is enough sometimes you wanna slam it. Nice episode, can't wait to see the 4 link
Lance Hill explorers had 31 spline axles...
Lance Hill I see. I mean hey I just research and pass on my information that I find. Everyone is entitled to their own choices. I’m going 2018 mustang IRS, but my point here was he finds more value out of the 8.8. Maybe it’s the wrong decision, but we’ll see. I just don’t think he deserves 100 people bitching at him when there is value for the 8.8. It just all depends on your preferences.
Lance Hill I’m putting an 8.8 in my f100 and doing the c notch as well and the explorer axle is 373 gears and 31 spline if you did your research u would have found that the 8.8 is as good or better for this truck than the 9 inch that came in it
Disc brakes
You cannot keep the axles in it like a 9 inch
330-Garage You need to watch one of your fellow you-tubers, TexasKnowHow. He has a complete series of videos of doing the exact same things that you are doing. His truck is a 67 Ford F-100 so the suspension will be the same as yours. My local junkyard Never has a half price day.
I didn't see another video that shows what you did about the rear wheel offset. Can you tell us exactly what size wheel you went with?
Why would you replace a 9” with a 8.8?
thank you
Was just going to ask this. 9" is superior to the 8.8 although the 8.8 is very good. I also know first hand it's a pain in the ass to do a gear change on vs a 9".
Match a crown Vic swap lug pattern ?
Easiest way to get rear disk, choice of rear ratio, 5x4.5 bolt pattern. He spent $75. It will match the bolt pattern of the crown vic front swap. He will not even come close to the power handling capability of the 8.8 much less the 9in. So he isn't losing anything.
@@Moneypit330 Why do people put crown vic front ends in these things? I own a 99 grand marquis, crown vic with a different name. I also of course own an 86 F250 with twin I beam. The grand marquis drives nice, but the F250 drives every bit as good if not better, not sure why someone would want to swap a more expensive and complicated front suspension if it doesn't really drive much better. Must be for the lowering capability?
Stop working your day job and dealing with your personal life and make more videos!
unfortunately RUclips doesn't pay that well... doesn't even cover the cost of what i spend on parts....It would be a sad channel in a hurry hahaha
@@330_garage3 what did you end up doing to fix the rear end im having same issues
This truck is gonna be bad ass when you're done. Great job.👍
What year explorer is that rear end out of? I know some 8.8 have different axle lengths from driver to passenger but yours looks centered.
It’s not. They’re all offset like that. The shorter axle is on the passenger side
Looking good! I love the budget build you are doing! Try ranger wheels they will have less offset and 15 inch wheels will clear those brakes. I believe mustang wheels have less offst then crown vic specifically 94-04 but ranger is probably best. I can't wait for the crown Vic front swap ! This truck is turning out awesome!
What year did the 8.8 come out of? And when is your next video coming out? Lol
Russell Mcroberts he just
said it came out of an explorer
Yes I heard that, but different years and models had different ratios and some were LSD and some weren’t.
@@underconstructiongarage yes mutiple gear ratios were available most v8s got 3.73 and v6 got 4.10 but some got 3.55 all were 31 spline in the explorer 91-94 had drums 95-01 had discs... Sport trac through 2005 would be 8.8 axles along with explorer sports axle tag will have 3L73 or 3.73 denoting gear ratio and an 8.8 will be nearby telling you its an 8.8 a simple google search can give you axle codes for rangers and explorers to tell you your axle ratio and whether or not its a locker.
Dude it an optical illusion , unless you were touching the frame rail with the string !!!!!
The 8.8 is a decently strong axle not exactly 9" but can take decent abuse, I have yet to kill my 8.8 in my 90, I have upgraded to a LSD, aluminum cover with main cap supports and removed all the bearings and seals and replaced. They say you can weld the axle tubes to the center section to give it more strength, also that explorer 8.8 should be a 3.73 with disc brakes so a bit of an upgrade as well. I have no hate for the 8.8, when it comes time when my 410W blows up the 8.8 I have a 9" out of a 81 pickup. I think he'll be fine for cruising around and the odd peal out.
Pre 72 9” is only 28 spline,, the explorer 8.8 rear is 31 spline and bigger bearings it is a upgrade
Hey We’ve got 70,000 members that would love to see your videos. How do we contact u? -admin/owner CraigerCoClassic/FordF100World
Always look forward to the vids good job man
You spend way too much time worrying about the plate, not matching the curve of the top of the frame all you needed to do is grind it to match before welding it .
Several months late, but for anyone else with the wheel space issue, could try a set of wheels from a Panther (crown vic/grandmarquis/towncar) made in 2002 or before. they have a different offset but the same bolt pattern. They made the axle wider in the 03 model to match the wider front end needed to fit the rack on 03+ models, and in turn made the wheels sit really deep to try to keep the same over all width wheel to wheel. TLDR pre 2003 model Panther wheels have like 2 inches more clearance.
I know this was years ago when you did this, but your angled pinion shims were only covering up your pin because you didn't flip the locating bolt in the leaf springs upside down. I think you went to a four-link anyway.
I still don't know how you blast through these projects so quickly! How'd the dyno go in the end? Did you get back on it after the radiator fix?
hahah I have a schedule with a budget i'm trying to stick to. I try to knock something out every weekend. Got the radiator welded back up the next day, and put it back in. Was able to drive the truck around a little and play with it. Truck rides and drives like hell, so was even more motivation to get some decent suspension under it

Why remove a 9" rear end for something built weaker.? So many after market stuff for the 9" also. Good luck.
Did you use the 8.8 stock or was the passenger side cut down so the pumpkin was in the middle instead of offset?
Why Don't get a 8.8 out of a Crown Vic........Since your putting a Crown Vic front end.
Vic rear doesnt bolt in right? watts and 4link from factory?
Next time take a string line from your pivot point , front spring bolt and arch it from the center of your axle to mark center of your bracket. Old school.
Had no temporary support across the top of the frame keeping it straight,and when you cut a notch out you hit it with the hammer the back of the frame look like it dropped probably a half an inch then you trim the notch up to fit. But the back of the frame is still down. not good.
Bro I don’t work with metal but I’m wondering why he didn’t tack a piece of square tubing right across the top until he was done…. 🤷🏻♂️
Brakes AND Steering functional? That’s askin a lot
😬
Good stuff bud. Enjoying and appreciating your content. You're able to articulate your thought process in the middle of a project very well, which is no easy task. If Keep up the good work!
What year explorer axle
What settings are you using on your mig welder?
I love F100... Here in Brazil is a great success... see the history in my RUclips Channel... have english subtitles...
Why not flip the centers of the steel wheels then everything would fit for near zero$
lowering a truck has never made sense, makes them look stupid and defeats the purpose of a truck to begin with, but hey it is your truck.
ya, he should put it back in the field and let it rot because you dont like it. that is what hot rodding is about. we dont all like the same things.
It isn't for hauling douchebag. It's a cruiser. Relax.
If you didn’t do the 4 link what other options do you have for shocks? Can the stock explorer shock mount still be used with the stock f100 frame shock mounts?
yeah, you can leave the stock spring mounts/ spring hangers on the explorer rear-end and use them with the F100 upper shock mounts. Or upper shock mounts are pretty inexpensive, you could add a couple new ones to the F100 frame.
Crown Vic has weird off set
Is this guy related to matt damon?
Mike R he’s a dead ringer for Chris Pine
Hey I just wanted to say thanks for the details on your installs. I have a 65 F100 short bed and your videos have solicited my plan for a Vic front end, notched rear with an 8.8. Question, what size wheel adapters did you end up using on the rear end? Thanks, Adam
Nice, yeah I used 2 inch spacers to get the wheels and tires to clear the bed
Why a c notch rather than a step notch? (I know with a step notch you would have had to modify the bed too).
haha just for that reason, I didn't want to cut the bed floor out of this truck. If I decide its not low enough when its all together... I may go back and do a step notch.
Good job! I built a '72 prostreet back in the 80's. I narrowed my 9' ten inches and used a triangulated 4 link with coil overs. I didnt have to cut my frame and put a 31x16.5x15 mickey on 15x14 dragstar wheels. I had enough clearance between the tire/frame, tire/fender but did have to cut out my wheel well to the frame. Mine didnt sit in the weeds like yours did but I also didnt have much option at the time to lower the front. I only had 3" drop I-beams on the front. It sat nicely but still drove like a '72. Im sure yours will drive much better. Subscribed and enjoying the build.
nice!
Awesome job. I have a 70 F100 sitting in the garage that my wife gave me as a Christmas gift. I have started some body work on it and have sourced a new engine but I really need to get my butt in gear and get some work done to it. I wish I had access to a junk yard to purchase parts from. For some reason they have all crushed everything and closed up shop in my area. I just need to bite the bullet and make the 6 hour drive to the closest pick a part and make a weekend out of it.
After watching your videos I finally got my butt in gear (the warmer 40 degree weather helped also). I'm picking up a crown vic front end 7 hrs away next week and I found a rear end out of an explorer that will be delivered (the guy is going to bring the whole vehicle on his wrecker to my house so I can pull it) locally this weekend for $50.00. Engine should be ready for me to pickup in the next couple of weeks. Still looking for a C6 transmission. Thanks for posting your video's.
I love to hire you to lower my f250
For gods sake get some paint on that frame!
Explorer 8.8 rear ends have an offset of center differential. One side axle tube is longer than the other side.
I was just gonna say, I'm told the fix to go full size to to make 2 axles into 1 using the longer tubes and sell the shorter ones to a guy with an old ranger
Dallas Stars! Love the shirt. And the truck
because it is just as strong as 9in and hes going to the crown vic swap its the same bolt pattern as the 8.8
AND it was $75 for a complete rear end with calipers, discs and lines. Rear disc conversion kit for 9" is $350. Traction lock carrier is another $275.
@@chucksgarage7165 makes sense
Great work!!! Did you do anything with the center section being offset, or is it okay to leave it?
Plenty of room under the trucks to leave it offset. The cars can give you an issue with the center section hitting the body.
just band the rear wheels and make your own offset to suit the truck unless your going for a different type of wheel then you will have to got for the same offset and or a spacer depending
I just picked up those wheels at the junkyard because they were dirt cheap and would let the truck be a roller still. I planned to go with a custom wheel in the coming weeks.
@@330_garage3 i thought you were keeping the whole patina look and stock steels but a nice custom set of one off wheels will really make this truck. Fantastic video as always and full of great knowledge 👍👍
Too low , too low.
You probably know this by now but I think that the 8.8 has two different axle widths on each side and is mounted off center in the explorer.
This is good info.. a lot of guys want to use those explorer rear ends in the mustangs etc.. and can't because of that offset-center. (It hits the bottom of the car)
@@330_garage3 what size wheels/back spacing did you end up using
What year did you take off the Differential??
I Think it was from a 1998 or 1999
Could you use the stock rear ended with the same coil over kit you purchased?
I’m swapping out a crown Vic front on my 67 f100 and want coil over in the back bit don’t want it to get lowered too much.
Just get some coil overs!
Very interesting. Greets from the V8Lounge in germany. I also have some Truck Videos online.
Did the explorer rear axle sit lower in the back on your style stock suspension after you finished the crown vic swap frontend?
Yeah, same question,, why would you swap a 9" for an 8.8,,
Better gear ratio than what he had, made lowering the rear easier, not much weaker in strength when comparing stock equipment, and he also gained the ability to run a much cooler looking deep dish wheel. Though he obviously didn't consider that
@@edjackson4389 I considered the cooler wheel!... just haven't ordered them yet haha! I didn't want the truck stuck on jack stands and thought the cheap crown vic wheel would at least let it roll around
@@330_garage3 That's good news! I hoped you weren't gonna stick some pizza cutters under that hot rod. I had a 68 with 15x10s with 265/50-15 tires on all 4 corners back in the 90's. They rubbed a little but looked mean
Why take out a 9" rearend and use the 8.8(it's a GM clone) the 9" is a superior rearend. It is heavy though.
What size spacers did u use to angel the rear end
I found the cheapest 2" spacers I could get off ebay
I just got an identical one for my '72. What did you do for the yoke? I saw a couple different sizes for jeep swaps but dont know witch is the right one for the f100 can anyone help me out?
Looks pretty good What! What do you plan to use for an engine? I had thought about a coyote swap in my F150 but that is 10k that I don't have.
I am a subscriber because you are building the same truck that I built (even though I started before you I am not done with mine.) For the rear end, since the Explorer rear is so much more narrow than the CV front track, I went with spacers on the rear. I am also running 2016 Mustang GT 18s all around. BTW, you are doing a great job.
i have a 96 ford explorer no leaks in the rig from the factory very dry underside engines runs very good just it has body damage on top of rig and the windshield is broken has the 4,0 v6 4 speed auto doors and front clip is good have a parts one with a good top and extra front end selling all for 800 bucks can drive the explorer the top i pushed it up and made it look better but i broke the windshield but have way to many rigs i live in oregon will be putting it up for sell soon if i remember right it has less then 120,000 miles on it the 4 wheel drive works fine
I've done the same thing with my 69 F100. I started with the leaf springs and ended up putting a AirSlamIt four link. Crown Vic on the front. I cut the tubs out of my bed since the floor needs to be redone anyways but you'll have clearance with wheel spacers. I think I bough 2.5" spacers. Not ideal for long term but they do the job until I get away from my mustang wheels so something like that may be a temporary solution for you for now.
The Explorer is to narrow for a full size truck, you should probably use an F150 axle, I have Explorer axles on my Bronco II and they fit that perfectly!
Great vids. What did you use for shock mounts and shocks? The explorer bottom mounts don't appear to line up with the factory F100 mounts on the frame. Thanks!!
What type welding machine were you using ? It was wire feed but it had some thick beads ...
I am using a Lincoln Power Mig 210MP. It seems to lay down a thicker bead than I prefer sometimes. I continue to mess with the settings to try to get it dialed in a little better.
@@330_garage3
I see lincoln top nothchy ....
Inna few weeks I'm going to do a c notch when you disconnected the E brake to remove the axle did you take it off from the nuts on the cable ?? Looked like thats how you did it ...
@@TheThirdWheel618 yep, good question, it was easiest to loosen the cables where they connect (under the rear of the cab), disconnect them there, and pull the axle out with the cables connected.
@@330_garage3
Ok got it that's seems easier since I have a 250 anything I do to remove the drum I need to slightly pull axle shaft out not the best idea .
Love the vids thanks for the reply .
Why would you not notch the frame for the whole panel ? If you had when you ground the welds smooth, you would not be able to see the insert. And I also have the same question others have posted, why remove a 9 inch and replace it with an 8.8 ?
What are your plans for the 3 speed? Are you gonna leave it in or do you plan on something with an overdrive. My truck is or was like yours, 360/3spd.
too funny... when you lowered the back end I said, "Holy Crap!" Then you came on and Said the same thing. LOL :).
you make me want to cry i had a 1970 ford pickup that was fully loaded ac cruise power everything (doctor ordered it new) worn it out and sold it a few years back
what size/brand and backspace front and rear wheels tires did you purchase...thanks
At min 9:20 is when it all went wrong. He spends the next couple of mins correcting the frame twisting by trimming.
doesn't one side of the 8.8 have a longer tube than the other side? is the differential centered on your truck. I've seen some 8.8 swaps on cars where one of the axle tubes has to be cut to match the other side and to center the differential.
It would have made much more sense to four link it and air bag or coil springs it. Since you went to a car springs at front
the leaf spring is arced. when the spring is compressed and straightens out, the dowel pin on the spring moves backward as much as an inch
As far as replacing a 9” with an 8.8, I get it if you are CV front end swap for same bolt pattern
Please people , stop asking why would you do this , if you have to ask then you wont understand
Wait that's a cheap way to narrow the rear end man get some deep dish billets run a big lip in the rear problem solved
got a silly question i know has anyone ever put a front wheel drive under this type of vehicle like out of a modern car
Great job! Well done my friend. You’ll love the finished ride height.
What was the total inch drop you ended up with by doing the spring mounts and axle flip?
03+ crown vic wheels are +40 offset you need 0 offset depending on wheel width
Incredible watching transformation of this truck. Can't stop watching the videos. Curious if you put the old floor mat back in. If not would you consider selling it? lmk
Hey man what year explorer diff did you use? Or are they all the same?
Nice work.
Anxiously waiting on the IFS swap.. any idea when the video will be up.. i am loving the videos.
Oh to be young and strong again. I like the stock truck wheels.
2” spacers would fix the wheel figment issue.
you took the better rearend out of the truck those 9 inch rearends are bullet proof
Wow, that was easier than going with a spring on top by moving the axle mounts on top>>>????? Strange, weaker frame, expensive parts, etc.
What would you suggest to get the truck to sit lower.. mount the springs on top of the frame?
Love the truck!! I did a c notch on a full size truck and it developed a very annoying harmonic vibration to the rear end. It was super annoying and drove me crazy until I finally figured out what was causing it. It felt like a tire was out of balance but would happen at very low speeds. Learned that these c notch kits are not rigid enough. The prob is with the rear spring perch mounts being behind the notch it tends to flex just enough to feel it as you drive. Solution was a short loop to reinforce the frame but unfortunately it has to take up some space in the bed. Anyhow hopefully yours drives good without this problem and you can avoid the mysterious harmonic vibration 🙂
I am gonna put the same exact same one in there these axels are the best
What year Explorer did you pull that out of?
I admire the effort. However, I would think that the structural integrity of the chassis is severely compromised, even with the plates welded on. The welding itself creates stress concentrations, which are more likely to fail due to fatigue over time. Might work only if the frame is over-designed to begin with, and not used for carrying actual loads after the customisation.
It's just a cruiser dude. He isn't going to be hauling logs kr anything!
Just curious, why didn’t you just do a flip kit in the existing 9”? It’s stronger, easier to change gearing and axles.
$$$$$$$$$
Mustang IRS set up , sit nice, and give a great ride .
I have to cut the bed sow I can put a 12 in fat tires
I’m just going with a Crown Vic rear end. I’ll have to cut off all the junk and weld on spring pads.
Go with the 98-02 cv axles they are narrower than 03+ but best gear you will find is 3.55 in a cv.... Ranger fx4 lvl2 got 4.30 gears fyi
What year is that explorer rear axle from??
Order wheels with proper back spacing. Problem solved. $75 for a limited slip and disc brakes is a no brainer. Unless you plan on putting slicks on it strength is never going to be an issue.
Yeah I have a wheel and tire combo in mind. I picked up these crown vic rollers to be able to move the truck around in the mean time. Agreed. this truck will never see a prepped drag strip, so that 8.8 should be great
@@330_garage3 which combo you looking at? I'm hearings guys say either ranger or pre 03 vic wheels will work. Prolly not as sexy, but budget minded.
Explorers center section is offset to one side..
Wheel spacers are you best friend!
no no no ...dont butcher up this truck for this
WHY NOT?
@@spaceghost8995 other then getting disc brakes..you gain nothing by doing this,,,lowered trucks suck....
