Sounds to me like the diff is knackered, best bet in this instance is to get a complete rear axle from a breakers yard & swap them out at home, its not a hard job though some use of strength & brute force is required, I done mine at home on my own with limited/nonexistent mechanical knowledge & a haynes manual - a chilton is basically the same manual, one thing i would recommend is that you get replacement suspension arm bushes & panhard rod bushes unless yours are in tip top condition as it saves a lot of hassle in the long run & if they're shot or on their way out then its best to change them while you got the back up in the air.

Yes it does.Without a lot of info its hard to say what's the problem.It will be either the wheel axle bearings or the differential.It may also be the brakes.Loose or badly worn.Hope this helps in some way

A differential can make a variety of noises when it's failing. It can whine, howl bang or grind, depending upon what is failing and how severe the problem is. Axle, pinion and carrier side bearings can make noises as well as the gears themselves. With the exception of axle bearings and possibly spider gears, working on differential problems is an exacting procedure that requires careful measurements etc that even many decent techs cannot do properly. Carrier bearings and gear failures will often create enough fine metal contamination to damage everything else in there. New units are expensive as are replacement gear sets. Most times it is far easier and less costly to obtain a "drum to drum" unit from a scrapyard. Replacement is then a bolt in procedure. Only item that is critical is that you must match the gear tooth count on the pinion and ring gear exactly to what is in the old unit. Not doing that will cause your transfer case to fail. Never put any differential back in service without draining and re-filling the oil.

Often it does, but failures happen without any grinding also...It depends on what fails....

Ford explorer 2011 rear axle wobbling and propeller shaft hitting the fuel tank bracket possible causes.


Sorry to say it sounds like you have a bent axle, If you mean Drive shaft when you say propeller shaft, then that's either because you also bent the driveshaft or you have u-joints that have gone bad. It sounds like a mess, Did you hit something or run over something? Rear axle don't just get bent form nothing. Has there been a grinding noise for awhile coming from the rear area? Your axle bearing or wheel hub bearing may be shot causing the wobble,

Bad clunk from rear of vehicle can drive it


if it is a metallic clicking/grinding, then it is the axle bearings. get them serviced in a shop (unless you know a buddy with a press), because, if it really is the half axle bearings, it could eventually grind thru your axle, and cause an accident

That sounds very bad, Jorge. Don't drive it any more until you can either get the differential rebuilt or get the axle replaced with another good axle with the same gear ratio.

Rear diff noises


check the axle bearing on the side . jack up the car and try and pull the axle in and out of the diff housing. If it moves then it will be a bad bearing.

Grinding wining noise when slowing down cruising at slow speed, not turbo wine and the noise does not change when turning left and right. 2004 2.0 TDI Audi A3


This may sound obvious, but I would have your brakes checked out, just to rule them out. Many shops will do a free brake inspection.
If the noise is coming from the engine, look for a "Check Engine" light. If you see that, then have someone hook up a scanner to check the codes thrown by the car's computer and go from there.
A grinding noise is not something you want to put off or wait to fix.

Getting grinding in rear.is it u joint or differential?


Hard to say exactly from here. However, The u-joints usually start to squeak before going bad. Park it on a level surface in a safe place and make sure it can't roll. Put it in neutral and crawl under it. Twist the shaft a little to see it there's play in the back. Might be safer to just get the rear end up on jack stands. If it's a "grinding" noise that gets worse under deceleration it's probably the rear. Also check the inside of the rear tires to see it there's moisture (gear oil) from an axle seal leaking, and/or bad axle bearing. There's an option tag either in the center glove compartment, or on the passenger's side door that will give you the axle ratio. "G" code, Like GU$, GU6,GT5, etc.

It makes a grinding noise and only on the passenger side. just started making noise when turning


Check brakes, then check axle bearing. If brakes check out OK, then jack up so the wheel is off the ground, put car in neutral, now spin the wheel and put one hand on the coil spring, if you feel any roughness, the bearing is bad.

Rear direrintial


The rear diff. turns the rear wheels. It is located in the middle of the rear axle. It won't last long if you ignore it. May just need dearing's but if it is driven the cog wheels will grind to dust or drop off this can cause the rear axle to seize up and can be a danger because the back wheels will lock up. If you are going to fix it yourself let me know and I will be able to guide you through the process
