Question about Cars & Trucks

Front differential noise.

I did a tcase rebuild 3 mths ago for un related problems.That problem is fixed.U joints on front and rear drive shafts seem fine.Actuator switch seems fine.Truck does not give me 4wd problems in 4wd h even at highway speeds.If I try to to back up in 4 l as I did today there is considerable clunking coming from front diff and I can feel it through steering wheel,sounds like gears or splines not meshing of jumping out.Truck has 142k on it.

If you were on hard stand and not on gravel or loose surface then you will experience drive line torque wind up which stresses all loose parts in the entire drive train including the gear box and transfer case.. You may have worn "U" joints or cv joints in the king pin /ball joint area If there has been no service on the front drive axles and joints then the problem may be coming from there.

SOURCE: 1996 Audi A4 Quattro has a noisy rear differential

It's the wheel bearing. Guaranteed. Just replaced mine. Go to Audiworld tech articles for step by step instructions on how to test the wheel bearings. They must have been put in wrong last time or they just went out again.

SOURCE: 2004 Ford F-150 extended cab FX4. 4WD problem

Your front hubs are automatic locking hubs, and the gears are hard nylon. These hubs break very easily, therefore causing you to lose your front wheel drive in 4 high, or 4 low. If you replace the hubs with "WARN (name brand) " manual locking hubs, you will never have the issue again. Of course, you will have to get out of the truck and manually lock the hubs, but they are metal gears, and much more durable. I've personally seen the issue several times, and changing the hubs has resolved the issue every time.

Dodge ram 4 wheel drive noise


check the front drive shaft spline or "U" joint at the transfer case
splines on this shaft wear more quickly that the rear drive line
as the operation angles for the front diff are more acute that the rear shaft

My ram 1500 makes loud clacking noises and it gets worse when the t-case is locked in four wheel drive hoping it's the tcase and not the front end but not sure how can I tell


I suspect that it is "U" joints or cv joints that is the problem
remove drive shafts and lock the t case in 4x4 and see it it makes the noise
refit the rear drive shaft after checking joints and if still no noise connect the front shaft. if the "U" joints checked out then it could be the joints in the drive axles at the pivot point ball
remove a hub drive plates and see if the noise is there
if it isn't then I would consider the joints in the axle shafts to be candidates for repair /replacement
it all has to do with the torque wind up when in 4x4 and any worn or failing joint will clack as it tries to work

Was told drive shaft was worn out needs rebuilt or new any 1 here of this


Rebuilding them consists of new U joints and maybe balanced. If it was so loose the the u joints wallowed out the keepers, Then yes, they would also need replaced. Cut off and welded on. That isn't a common problem, but I have had to replace a few. Not just on jeeps.

Why rear wheels are locked up but front are not


the first place to check is then rear drive line "U" joints as fail on a regular basis and can be not allowing the shaft to turn properly
T check for diff , jack up one side and engage a gear
if the wheel spins then the diff is turning but if it makes a bad noise (all will rumble a t a low level in this position) the diff will be faulty
It is possible that a joint flange has come loose and the bolts are jamming on the back of the transfer case housing

Transfer case troubleshooting


I would look at the u-joints before looking at the Tcase. Lift the front end (both wheels) off the ground at same time, crawl under and shake the front drive shaft. up down side to side. If it's tight the let front end down and get the rear end up in the air (both wheels) off the ground and do the same this to the main drive shaft. If the rear U-joints are failing (closest to the read Diff) take a real good look at the Diff. Make sure it's not leaking fluid, If it is you may have a bad pinion starting to go out also.

Violent clunking when truck starts moving. checked obd codes nothing showed up. possibly engine mounts or bushings?


It's hard to tell, from your description, as to the extent of the clunking.
If it seems to only and constantly occur whenever in forward motion, bumps or not, then I would first check your rear differential, (if 4x4 then your front differential as well).
Check fluid level(s) and if okay, remove cover and check for worn gears and any metal shavings on the magnet on bottom of housing.

Worn gears can toss your vehicle around, any make stomach turning clunks and other awful noises. I've recently replaced a front differential on a 1994 Dakota. It would make same clunks as you describe and a few times would make my back end seem to 'hop' while driving highway speeds. I would check this quickly.

If it only seems to happen over bumps, then your guess on engine mounts or bushings is probably the best guess.

I have a 05 Cadillac Escalade and the sterring wheel shakes when I'm driving on town streets and on highway. I brought it in for service....and explain to the service people my problem. All they did was...


Have them check the universal joints, front and rear, as well as the two on the front shaft if it is a four wheel drive model, the CV joints on the front axle if 4WD, the drive shaft(s) for straightness, mud in wheel recesses, and the rear end and front differential "chunks."

Whining/grinding noise at deceleration


We have the same problem at our shop. We haven't rebuilt the front differential yet. We tried 3 different shafts on 2 different Jeeps and the noise is on both just the same. By greasing the front driveshaft cv joint, we got he noise to quiet some, but it is still way to loud. With the driveshaft out, the noise is gone. We are about to buy a new shaft from the dealer for $600. There are some service bulletins about some noisy driveshafts.
