daves16v 1 Posted January 19, 2005 A few weeks back my wheel bearings started to hum and I've only just got round to fixing them but I'm having a problem finding the offending bearing. The noise gets louder as I speed up and can come on after turning a corner but I can't tell which wheel(s) are noisy. Jacked the car up today and spun the wheels - no noise evident. There was slight play in one rear wheel. Do you think this could be the problem and can I tighten up the hub to take up the play? I don't think it's the tyres as they were new about 7 months back and have never made a sound. I'm fairly sure it is the bearings as I've heard this noise before on previous cars. Any advice greatly appreciated. Thanks Dave Quote Share this post Link to post Share on other sites
G60Jet 1 Posted January 19, 2005 play in the rear wheel, clues are there mate Quote Share this post Link to post Share on other sites
alby 0 Posted January 19, 2005 tbh i dont think you are going to able to spin an unweighted wheel fast enough to hear any droning. just replace them on both sides. they arent expensive Quote Share this post Link to post Share on other sites

Supercharged 2 Posted January 19, 2005 You can tighted them up using a new split pin, bear in mind they need a bit of play as they heat up and expand... If they are noisy tho the problem won't go away! Quote Share this post Link to post Share on other sites

dr_mat 0 Posted January 19, 2005 Could be the brakes binding on the disks - particularly if you have grooved disks.. You can tighten up the rear bearings, but the fronts have no adjustment - if they've gone they have to be replaced. It's usually hard to tell if it's the bearings on the front, due to the drive shaft going through the middle, but you can usually feel some grinding or lumpiness as you turn the wheel if they've gone.

daves16v 1 Posted January 20, 2005 The rear driver side was the only one with slight play. There wasn't any grinding or lumpiness in any wheel. I'll tighten up the rear wheel and see how it goes. Quote Share this post Link to post Share on other sites
daves16v 1 Posted January 20, 2005 Can someone else confirm that I can just tighten up the rear bearing. dr_mat, I'm not doubting you mate but a friend told me the rears are not adjustable. Quote Share this post Link to post Share on other sites
dr_mat 0 Posted January 20, 2005 Someone told me the rears weren't adjustable too. But they were lying.. ;) Remove the split pin, tighten the castle nut until you can just about turn the thrust washer by finger pressure (or a small screwdriver) and then fit a new split pin. I'm sure other folks will confirm that this is all fine. Just don't over-tighten. It's worse than being slightly loose. Bear in mind it's going to expand slightly compared to when you're working on it cold. Quote Share this post Link to post Share on other sites
corradophil 3 Posted January 20, 2005 They are taper roller bearings which are adjustable, definately. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 20, 2005 Don't tighten them up Dave. They have to have play and if the passenger side one has no play at all, introduce some ASAP. It's probably that one that's droning... Quote Share this post Link to post Share on other sites

theRuler 0 Posted January 20, 2005 dont swing off the wrench when tightening. there probably is a torque setting (a very low one). but you shouldnt be able to physically feel play in them. you just get a feel for how tight they go. Quote Share this post Link to post Share on other sites
daves16v 1 Posted January 20, 2005 ok, now I'm confused even more......... Quote Share this post Link to post Share on other sites
alby 0 Posted January 20, 2005 as said above.tighten the nut until you are able to move the washer with light pressure from a small screwdriver. Quote Share this post Link to post Share on other sites
daves16v 1 Posted January 28, 2005 After tightening up the play in the rear bearing, the noise was reduced slightly but still evident. So I bit the bullet and had both rears changed yesterday and now I have NO noise :D Quote Share this post Link to post Share on other sites
theRuler 0 Posted January 28, 2005 nice one!!! noisy bearings suck i had a front bearing on my mk2 golf get so noisy that it would make a thumping sound. so i thought "oh go on then, i'll replace you" Quote Share this post Link to post Share on other sites

theRuler 0 Posted January 28, 2005 i have to change the front bearings in my c-vr6 in the coming weeks. do the outer cv joints just slide out? or do they have to be pressed out? (out of the old bearing i mean) Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 28, 2005 Yep the CVs slide out....same setup as the MK2 golf.... Quote Share this post Link to post Share on other sites
dr_mat 0 Posted January 28, 2005 I was driving around in an old Jetta TX for about 4-5 weeks with a clunking front wheel bearing because the garage wouldn't commit to whether it was the bearing or the CV joint.. (Being a student at the time I didn't wanna fork out dosh to find out...) Eventually I worked it out when there was around 2-3mm of play at the top of the wheel, which accompanied the clunking..!! I rang the RAC tech line who suggested I get it towed (he was pretty horrified), but couldn't be bothered with that and just drove it carefully to the garage.. :) Quote Share this post Link to post Share on other sites
theRuler 0 Posted January 28, 2005 cheers. and i'll bet the big nuts on the outer cv's are done up 10,000 foot pounds of torque too. the last one i undid was a strain. i looked like deirdre barlow having a difficult sh1t. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 28, 2005 Not quite 10,000 ft/lbs, more like 8,876..... Let's just say you'll need a 200 ft/lb torque wrench and some bricks behind the wheels when you do the nuts up again :wink: Quote Share this post Link to post Share on other sites

Looking at the size of you in your animation you'll have no problems :wink: Get someone to put their foot on the brake pedal whilst you loosen it.
