    Its a proper roller bearing, so you'll need a big vice or a press to shove the old bearing out and press the new one in. Same idea as the front end.

    The rear diff has had weeping seals from when i got it so im going to do the oil in that. It may be that thats making the noise but sound like a wheel bearing to me.

    Prob is a bearing then tbh mate.

    My diff is damp too, spose i should check my oil too. Aragorn been in my tank, You recon it's bearing on mine?

    Ian if it's obvious from one side or another or changes withe cornering load it's more likely bearing

    Cant mind hearing any bearing noises in yours mark.

    Craigs S4 is a bit rumbly, and we put it down to the diff running low on oil for a prolonged period. Not sure if its quietened down now its full.

    A little tip for doing the diff oil, get a length of garden hose, thread it down thru the wheel arch into the level plug (thru the wheel if that helps with alignment) then one person undernearth holding the pipe in the opening and watching for it to overflow, and someone outside carefully pouring the oil down the hose. Worked a treat on craigs (and on my gearbox incidentally)

    Good tip that....I used a pump and squirt (scuse that!lol) garden sprayer from B&Q. Compresses the air inside the bottle when you pump the top, and soon as you pull the trigger whatever fluid you have in it shoots out. Does 2 ltrs a time. Really quick! Just attached on old breather pipe to the nozzle to get the fluid in the fill hole. All this because I couldnt find a turkey baster!.....

    I still got a similar sound cooming from rear. Whistling high pitch humming. Sounds like the noise when you blow in the top of an empty beer bottle. Tempted to pull the bearings and see if its them and not the diff. But no time....I'm still at work now for christ sake!

    did a bearing not so long ago. about to do the two new rear uprights so they have fresh ones.
    some advice: get OEM or Meyle bearings. Euro Car parts do some cheap ones which don't last. (dephi or something similar IIRC)
    The bearing is also sided, it has a off centre lip internally that needs to go in the right way round. you will see when you take it off.
    be careful when you are handling the bearing as if you make an arse of it the centre will pop out and the nice clean greased up bearings will land in all the **** on your garage floor.......as me how I know!

    I have an old bearing case with some metal ground off to use as a drift in the press/vice. once you have something suitable to press them in they go in fairly easily

    We did the front bearings on ours using my mates vice.

    Oddly Audi dont use circlips on the front, and as a result the bearings are a MUCH tighter interference fit than most cars, and he was really struggling on the vice handle.

    If the rears are the same, then be careful as if the vice isnt strong enough you'll split it in half. If the rears are circliped it should be fine.

    Anyone had any trouble with the hub being worn and needed to replace that too? Or have most people managed with just having the bearing replaced?

    Currently got a dying N/S rear bearing for mine and need to source parts!

    i used a press for mine, been there done that with exploding vices!
    It didn't take a lot of pressure, a lot worse on a Mk2 Golf!

    never had the actual hardware be worn. what is worn on yours?

    My NSR bearing died shortly after I got mine at 110K miles, the other one was replaced with 10k miles after that. The rumbling that I get now is the back diff, as I go around roundabouts on the throttle. I would have hoped the stealers might have checked the level when it was in last year, but I might check it anyway. The car is at 152K miles now both back bearings all ok. :)

    It was just a guy selling them as he never used them. I was going to be about £30 for one at a fectors and it wouldnt be mayle or anything so £20.50 to my door for 2 is a result. Thought i might even get them for 99p but no such luck.

    I had to replace my drivers rear last weekend for the MOT.

    First thing the car has needed for an MOT. I think mine was just one of the Delphi ones as I needed it super fast, hopefully it lasts a while. It cost about £30.

    The original bearings have lasted 79k.

    Sorry to hi-jack the thread but i have similair problem, Although mine is worse! Firstly i had to angle grind the bottom bolt off as it was not coming out, I had to grind the tie rod balljoint off... So im left with the rear axle, (b5 quattro tdi) How the hell do i get the bearings out? I know it needs a press or a big vice but i cant seem to grasp the procedure, Does the splined half shaft stay on or come out first and how? Please help me, Can post pics if needed.

    If you dont have access to a press etc take the hub to a garage and just get them to press it out. Mine took a good few tons to press out.

    Hi there, Thanks for replying, Did you reove the hub yourself,if so, did you leave it complete (with the splined stub axle/hub still in situ between the bearings) Thanks pal.

    Managed to remove my stub axle with a homemade puller (3 bolts!!) Also got the outer race out with a big socket and an even bigger hammer, Inner race was badly pitted and one ball bearing was badly damaged, Who needs a press? If anyone needs info on this i'll be glad to help in future, Will be getting new bearing pressed in as a precautionary measure!! Have a Meyle in the mail!! (gets coat) :sadlike:

    Well thats the thing, you could do all that, but i wouldnt want to risk damaging the new bearing, and if your taking it somewhere with a press to push the new bearing in, you may as well just get them to shove the old one out, save messing around with hammers etc.
