    Wheel Bearings

    Anybody got any experience replacing wheel bearings on an S3?

    I have noticed a grinding noise when the car is moving and suspect the wheel bearings, however can anybody suggest something else that may be causing the noise.

    My S3 is just over 3 years old, with 34,000 miles on the clock, therefore I think it is a bit early for the wheel bearings to be on there way out.

    Re: Wheel Bearings

    Wheel Bearings generally "Drone" as they are of the pressed in variety and are non adjustable, therefore I'd be inlined to go for brake linings than bearings... Have a look first..and let us know how you get on.. [img]/ubbthreads/images/graemlins/smile.gif[/img]

    Re: Wheel Bearings

    I would agree, could it just be a stone or road grit caught between the disc and back plate etc?

    Re: Wheel Bearings

    I just had to change my rear right wheel bearing on my S3. It has done approx 65.000 km (40.000 miles) so it seems a bit early, but I guess if the seal in the bearing unit is damaged in some way, It will wear out.
    I heard no noise or anything, just felt a small free play in the bearing when pulling and pushing on the wheel with the car jacked up.
    Now afterwards I noticed that the car is a bit more quiet so I guess there was some kind of noise from the bearing after all. The driving stability is also a bit better.

    Luckily the rear bearings are cheaper to change on an S3 or A3 Quattro than on the FWD models.. I paid approx 150 GBP (converted from SEK) including both material and labor.

    Re: Wheel Bearings

    Thanks for the advise and information. Perhaps "grinding" was a poor descirption of the noise, whereas "drone" is more like it. I haven't had an opportunity to investigate further yet, but I will keep you informed.

    Re: Wheel Bearings

    Jacked up each corner of the car in turn to check for any free play and / or noise from the wheels, but nothing was evident.

    Noticed that the droning noise becomes more evident when slowing the car down.

    Any ideas?

    Or am I just hearing things?

    Re: Wheel Bearings

    It may be the tyres! Are they low?

    I had this problem and was convinced it was the wheel baring until I spoke to my dealer and he said that it could be the tyres! changed my tyres and problem went away!

    Hope this helps

    Re: Wheel Bearings

    my A3 T sport 99 T started making a very similar noise recently, it did sound like a grating noise or a drone/vibrating sound. i knew the brake pads were worn so assumed it would go away when i got these changed, but it hasn't.

    I have fitted S3 alloys to the car but cant see this causing the problem or am i wrong?? it does make the sound more when cornering or under slowing or braking.

    I think this sounds like the wheels bearings. would i be correct in thinking this given the symtoms??

    I have tyre whine, that sounds just like a rear wheel bearing!! I know its tyres as I had the car on a ramp, in gear with all wheels turning and used a stethascope to listen ot the bearings, all quiet as a mouse!

    worth consiidering the tyres, worn dunlops are notoriouos for noise!!

    Only way to tell for sure really is to jack the car up and run the wheels - be warned if it is a bearing change it sharpish they have a right nasty habit of destroying the hub flanges

    Did you fit new tyres...? Some tyres when worn are just noisy, if the fronts and backs are worn you replace a noisy tyre with another! !

    If they were new, sounds like you have a problem.

    Had same tyres b4, so know what they sound like, but know what ya saying regards to that. Have changed tyres around and still have thesame noise, so that wud sujest tyre and wheel are ok. just makes a wurring noise between 25 - 35mph, dont feel any vibe thru steering either, just slight judder under braking, but that doesnt happen all the time...so any other ideas??

    Wheel bearing mate, they tend to go in 2's

    jack the car up and grab your wheel from top to bottom and see if there's any play.

    No play at all, 1st thing that was checked! Bearings can go at anytime, not normally in pairs from past experience!

    bearing

    Guys,spinning the wheel and checking for play Top and bottom, wont always work..
    Lots of front hub bearings now are "Dual track" bearings , It's a bit like two bearings stuck together!

    Only when w8 is on them might you hear some noise..
    not sure the type of bearing on your car though!
    only putting you in the picture..
    regards

    It was the tyres on mine. They had feathered badly as they had worn. It sounded terrible, especially on the rears. Even the garage commented when it was on the RR. There was no play in te bearings, changing the tyres completely sorted it. Its happening again now as the tyres are almost at the end of their life. (Avon ZZ3's)

    Though yours may be different of course...

    Sluggy, your on 4wd so changing tyres round may not sort it if they are all wearing at the same rate (or at least mine do).

    I agree, the tyres it seems to do it on are the very hard wearing and hard compiund ones like dunlop sp9000s and Avon ZZRs..

    Why not see if a fellow member nearby will swap the rear wheels and tyres over for a test drive..... May be all you need.

    If its wheel bearings, bet on about £120 a side form a dealer, fitted up, if its diff bearings, I am not sure they are available as spares form audi, they tend ot only sell you a whole diff for like £2k!! Fingers crossed its tyres or wheel Beraing!

    There is an Audi diff/haldex unit on ebay, now!

    Its off a 225 TT, but our Quattro's share many similar parts, may be worth a look..
