Noise When in 4WD Auto Turning Corners 2019 Ram 1500 Laramie Longhorn
HTML-код
- Опубликовано: 4 окт 2024
- My 2019 Ram 1500 Laramie Longhorn has a very noisy 4 wheel drive Auto system. I can hear louder than normal driveline noise with my foot on the gas when in 4WD Auto. The noise is like a scraping or groaning noise. The noise gets much louder in tight turns. I get no wheel hop. The owner's manual states you can use 4WD auto on dry pavement. Of course I would never try 4WD High or 4WD low on dry pavement! The 4WD Auto system is designed to sense slippage and engage the front wheels when it happens. 4WD high and low have the front wheels engaged all the time and should never be used on dry pavement. But, my 4WD Auto makes groaning and scraping noises when in use. Others on 5thgenramforum who gave the same truck day their 4WD Auto is whisper quiet.

glad you posted this. I have the exact issue. going to make an appointment to take mine in. happens on rain snow as soon as i start turning
Good luck getting resolution! Mine still makes the noise.
The zone manager and the dealership both say it is normal.
Funny, the F-150s I drove or the Chevys never made that noise.
Mine can be so loud at times, that you think the tire is scraping the wheel well liner. Ugh..
It’s binding and front differential might need to be rebuilt. ( had my rear differential rebuilt because it sounded like metal to metal scraping while driving). Definitely have it checked out.
I did have it checked out and, of course, FCA said it was normal.
The truck only has 7,000 miles on it now. I bought it for retirement and it's not my daily driver.
It'll probably disintegrate after the warranty is up.
Mine does it too. One dealer said normal. Haven't brought to another yet - was too busy having them fix my drive shaft bumping problem twice.
Thanks for your comment Nick. My truck is in today to have the entire rear differential replaced - another separate problem. I wanted the service manager to ride with me to listen to what I am hearing in either the front differential or transfer case. . He said he would, but the noise is normal when in 4WD Auto. He said the Chrysler area manager said it is normal as well, so no point in a test drive. The owner's manual states you can drive the truck in 4WD Auto on dry pavement. Both the service manager and area manager said you should not. I want to drive another truck like mine to hear for myself. My Ford never did this. I'm so sick of dealing with FCA's factory defects for the entire year of ownership! This is my first and last FCA product. The service manager said they have about $15,000 worth of repairs in my truck so far.
@@cjspease are you the guy on 5thgen where they rebuilt the diff wrong?
My drive shaft would stick and then slam forward when letting off the brakes after a stop. First time, they replaced driveshaft. Came back within 500 miles - turns out the replacement shaft didn't have grease on the splines of the rear slip yoke. Brought back, dealer had to order a boot kit and the special grease, plus a special tool just to do the job. Got it back last night, it's 99% better but I can still feel it every now and then, ever so slightly. Could just be the 2-1 shift, but I'm so used to that hard bump that I don't know what's normal or not.
Not impressed either, but reading forums for Ford and GM - they're plagued with their own issues too. Kinda wish I went with the Tundra like I originally planned.
@@vietnamrebel Yes Nick, I am the guy from 5thgen with the diff rebuild, now to be completely replaced as we speak. Also Ivory 3 coat Paint issues, a bolt found in the heater box that rolled around and made noise, pano headliner fasteners issues, the harsh downshift from 2 to 1 ect., ect. I really wish I would have bought a Tundra as well. My cousin owns one - 15 years no issues. A coworker owns one as well - 10 years no issues. My Longhorn will keep these issues up over the course of its life. FCA has a world-class design with entry level quality.
So glad you are 99% better with your issue. I'm nowhere close.
@@cjspease godspeed sir. I've found the dealer makes all the difference in how well FCA responds. The dealer I bought mine from was useless, and the one I use now fights for me every time. They're already aware that the issue isn't completely resolved and told me to keep them in the loop so we can work on this further.
jack it up, check the fluid level, leaks around seals and mounts (diff and shaft).
I just got the ram 3 days ago and i have same issue . I got it from carmax 2019 bighorn 41k miles on it.. should i return it ?
Great video my 2019 5th gen ram used to do it even in 2wd test yours ,
stop vehicle make hard left or right turn and then accelerate vehicle on dry pavement warm or hot tires preferably they stick more and noise is more pronounced,when wet pavement or snow no noise from rear end.
To solve problem change rear diff fluid to Mobil 1 synthetic 75w140 with limited slip additive buy additional mopar additive for limited slip diff $11.00 on Amazon put whole small bottle in rear differential it will solve problem guaranteed if so you own me a beer 😀
what was happening since is limited slip diff (anti-spin rear differential) clutch pack was sticking not being able to free rear wheels when cornering trying to turn two wheels at same time which is good for drivetrain nor differential,
Most likely MOPAR used low quality rear differential oil with lack of limited slip additive ,I hope this can help.
(oem spec is 75w-85) I personally wound’t use it its a fuel economy. Scam to save 0,5 % on fuel economy same as CAFE agreements 0w20 oil between automotive industry and government they get credits for every vehicle using low viscosity oil (use 0w30 cold climates ,0w40 for south high quality synthetic oil) in your engine oil ,
Best of luck.
Thanks for this comment. I'm going to give this a shot in my 5th gen. Im having the same "rubbing sound in 4wd & 4wd auto" from front. Just confirming you do this for the REAR diff even though its a noisy FRONT?
Did you try it .. did it solve issue?
@@majedaltimimy6385
No noise from rear end next time i would go with redline 85w-140 limited slip gear oil and mopar aditive.
@@qrf7876
Rear end noise in my case ,
my truck is equipped with limited slip differential on rear end.
Try finding good size parking lot open up your windows make a sharp turns and see if you can pin point the issue,
I belive it is rear differential limited slip making noise clutch sticking you need better lubrication Red line synthetic Mobil one synthetic 85w-140 with limited slip aditive and wouldn't hurt to put additional bottle of mopar aditive problem solved guaranteed,
Rear differential fluid replacement is very easy and inexpensive nothing can go wrong,
Don't waste your time in dealerships
They will play stupid game.
I own 2019 ram 1500 laramie 52K miles mine i started producing noise @around 20k its been couple of years
3.5 inch lift,
Bilstein coil over 6120 front and rear,
FORGED aluminum uper control arms,
Custom exoust with no drone sound in the cabin,
35×12.5 ×20 BFGOODRICH KO2 TIRES,
Frequently towing 30 feet travel trailer 7k lb no issues even with the biger tires.
I can hear your transfer case going. It should NOT have engaged on the road.
usually it only sends power in rear wheel at 4 auto, when it sense a slip transfer will engage to lock, so it should be fine driving on dry pavements etc...
Auto mode transfer case clutch engages 4×4 if
Temperature is below 40 Fahrenheit
Windshield vipers on
Detects water on the roads
Detects wheel sleeping
Gear mode shifting activation + -
And when you start cornering sensing clutch input in transfer case reduces 4×4 to prevent binding ,
Best 4×4 system ever made unless you are going in heavy long off roading where clutch would overheat and 4×4 goes in reduced mode,
Ram 1500 Rebel models are equipped with good all direct locking 4×4 better for off road but not for driving every day in different types of road conditions snow ice dry payment.
Good Luck
There might be a future software update needed for how the system reacts to driving conditions.
Too many flipping computers... But from your video, my `97 EXPEDITION would have behaved similarly.
Thanks for the comment Mike. I hope there is a flash to fix the issue, if it does indeed exist in all trucks with the 3.92 rear end and 4WD Auto. Unfortunately FCA or at least my dealer will not offer the flash unless you complain about the issue again and again. I'll have to keep checking TSB's for updates. The entire year of ownership has been a completely miserable experience. Wish I would have bought an F150 or Toyota instead. All brands have their issues, but FCA appears to excel at them. Great world class designs but lack of quality and customer service to back it up.
I have a 98 f150... howls when i hit the gas already at higher speeds.. howls when i turn tight enough too... just replace gear oil in the front to find insane amounts of metal shaving it looks like liquid steel it was wicked... but the new stuff has dropped the noise down a little however its still there... now for the good part.. one thing the new fluid didnt change was the binding around turns... almost like the brakes are being applied. wanna know what a death trap is on a snowy road? Its when this problemcauses you to actually get sucked into the ditch when you hit the plowed up bank. So imagine 45mph on a road and then a turn comes up and you still going 30 to 35, well sometimes you hit the snow thats on the shoulder right? well with this binging issue it hits that snow and then the wheels almost lock up and the instability actually sends you off the road to the right cuz its a left hand corner and you're really just going straight.. well it feels like the brake is applied which would make sense... and with my rear breaks weaker than my fronts right now its making an easy drive a death trap... also im wondering if this guy had the front modified to a limited slip front diff.. that would make sense the binding... if its not a limited slip do you guys think my front end is failing?
Sorry to hear your F-150 is that bad. It sucks when you get stuck with issues.
Sounds like your 4wd is constantly engaged even when it says its just in auto, not good
The 2019 Longhorn has just been a royal POS. Quality sucks. Both the dealer and the district manager say the noise is normal.
Unfortunately my video did not pick the noise up well. I only have a cell phone to record video, not a camera.
The noise is actually so loud, that it sounds like the tire is scraping the fender liner.
Hopefully it will self-destruct before the warranty is up. Then maybe they'll believe something is actually wrong.
Yeah lol I would leave that in 2wd unless the roads are super slick, you'll definitely be grinding through some gears soon
I have 2016 ram same problem sounds front tire rubbing .?
Why not leave it in 2WD and only engage 4HI/4LO when you need it instead of 4-Auto? There is more chance the computer may detect slippage during turns and engage 4WD when you don't want it.
I do run in 2wd all the time unless there is inclement weather!
I'm just saying, I don't think the noises are normal.
I've driven many other brands and none of them make noise like RAM does.
It makes me feel like there is excessive wear taking place.
My 2018 Silverado does same thing. Truck shouldn’t be driven in 4wd unless in low traction environment. Basically the wheels are getting sent a signal to spin but if you are on a high traction surface that’s why you hear this noise
Can I understand what the benefit of 4WD on dry pavement would be?
There is no benefit using 4wd on dry pavement. The idea would be to use it when the weather conditions are slippery. But, when driving in winter weather, you never know exactly where the ice will be, especially at night. So, leaving the vehicle in 4wd Auto, allows the system to sense slippage and engage when necessary. My whole point, which was not picked up well by my phone microphone, is just how noisy my system is when it is in 4WD auto waiting for slippage. I know different manufacturers do things differently, but I just drove an F150 Limited and Raptor, who's systems were completely silent. There is a transfer case output seal ordered for my Ram as it is leaking. The rear differential has been completely replaced in my truck. Possibly, the dealer damaged the output seal when removing or reinstalling the drive shaft.
It's also great when you have to punch it from a stop to merge, etc. :)
Exactly 😂
I have the same issue, mine does it on turns when i am stopping and re accelerate. For example if i am stopping from 55mph and i reduce speed due to yield sign or so before making a complete stop i hear a grinding noise. Not all the time. Also on turns any solutions?? For your problem? Thanks
did u find solution? im having the same problem right now
Are you in 4×4,auto mode or 2WD
Did you ever get this resolved or looked at Chris? I'm going back for my THIRD attempt at fixing the drive shaft next week, tempted to bring this up as well since I get it too.
I never did get it fixed. As long as you are in rear wheel drive only there is no noise up front. FCA insists that the noise is normal. I obviously would not use 4wd on dry pavement, but I certainly would use 4wd auto, when conditions are uncertain - such as a day when there may be some rain, snow or ice. FCA replaced the entire rear differential assembly after they first tried to rebuild the ring and pinion gear. That was a miserable failure. The rear differential made all kinds of whines and noises after the rebuild. Finally they replaced the entire assembly. It's much better now. But as far as the transfer case or front differential, I'm not happy. You'd think they'd get it corrected after all these years of building trucks! There are way over $15,000 of just parts in mine so far to fix factory "F" ups. The video I recorded doesn't do the front noise justice. It's way louder than what the microphone on my phone picked up. The first time I heard it, I thought the wheel was scraping the fender liner. That's how loud it is! FCA has awesome design for their vehicles, but quality totally sucks.
@@cjspease wow, $15k? At what point could they have just put you in a new truck? That's insane brother.
@@vietnamrebel I fought with them, but no dice. I have the ivory tri-coat premium paint as well. All the plastic parts are a noticably different shade of white as well. FCA claims that is normal as well. I totally got screwed. This truck had a $70,000 window sticker. Unexcusable! It does ride better than the F-150's though. I took out a 2019 Limited and Raptor. The Ram definitely outclasses both in ride quality. Obviously the Raptor is the off-road version, but the Ram still has more finesse. I have the off road group with air suspension and the ride is amazing! Too bad the build quality is abysmal!
@@cjspease Yeah, that definitely isn't right at all. A shame they aren't owning up to the problems.
I too was disappointed with the ride quality on the F150's - I almost bought a loaded Lariat with the 5.0 before I bought the RAM. Part of me wishes I had gotten the Ford, but I see a lot of problems with the redesigned 5.0 in those too.
Just can't get quality anymore.
@@vietnamrebel You're right about the lack of quality or concern.
We outsource our I.T. where I work. The gentleman who services us was going to buy an exact duplicate of my truck. Once he saw all the issues that I was dealing with, he changed his mind and bought a Lariat instead. He got the smaller Eco-Boost 6 cylinder. For the most part he got a good truck, but he has had issues with the engine.
On cold days it intermittently loses power to the point where it will barely move the truck.
It's pretty much the luck of the draw when you buy something these days.
@Chris Pease
Same issue here in Germany, MY2021. Did you find a solution?
My dealer will install a clip in 2 weeks somewhere at the transfer case accotding to a FCA Bulletin.
I have no idea, how this could help.
I was told it was a normal noise by the dealer and FCA. I'm sure it is not normal! The video did not do the actual noise justice! It is actually so loud that it sounds like the tire is scraping the wheel liner.
I gave up on trying to get it silenced.
The truck is one of the worst quality vehicles I have ever owned.
The truck has under 8,000 miles on it. I'm.sure it will fail after the 8 year warranty ends.
@@cjspease Ok. My RAM has 25 TKm and I recognized the issue for the first time after 1 year and arround 19 Tkm (when I needed the 4WD in snowy / icy mountains).
I'll keep you informed ✌🏻
@@Spanferkelbraten mine has done it since day one. I'm sure something will fail eventually.
FCA told me the noise is normal. It does not inspire a feeling of confidence!
Did you ever get this issue resolved I have same with my 19 Ram
Raminator - jack it up, check the fluid level, leaks and mounts.
mine has this only when i go into 4wd hi/low I have a 2019 rebel with no auto 4wd. But mine seems to be a lot louder then yours almost like a grinding gears/hum when turning sharp left/right also happens more when steering wheel is fully locked almost like it would hesitate going when i would press the gas. Im taking it in for my first oil change this monday and they will have to check it out.
Did u solve the issue? My 15 sierra is doing this when in 4hi
@@jonathangodinez304 nope. My buddies who have trucks says this is normal I guess.....
@@nabatron21 well I guess I'll live with it
Have you had any luck figuring it out..? My new ram seems to be doing it unfortunately..
Is it just making noise on the turns
Yea the longer I drive the quieter it operates and I feel less through the pedal as well. Small price to pay for the best truck ive ever driven/owned.
@@t.jmatch2545 so basically it was when you didn’t have the 4 wheel broken in as much but it will always make a slight humming noise. It only doesn’t make it when you are driving on snow or anything it basically just needs grip. :)
I noticed this when I first got my truck but I never took it in, did they end up fixing anything?
