Wheel bearing shot?

When I was replacing my brake fluid, I used *considerable* force to pry off the NSR wheel as it has seized itself on. Since then I've been noticing a grinding sound from the NSR area when turning left, either a shallow turn at high speed or a tight turn at low speed - in particular corners I know to watch out for understeer on in the wet

I'm guessing I've done the wheel bearing in with the hammering/levering/kicking/etc - I know the alloy's looking a little worse for wear as a result. Is it a DIY job at the side of the road, or am I going to have to pay someone? What are the costs involved?

it might have just moved the handbrake brake shoes around inside the disk by all the shock of the hammering cos the bearing is designed to take quite a lot of shock , try pulling the handbrake up slightly when you hear the noise again to see if it goes but not hard enough to lock the rear wheels but i dont think you would have that problem with a 406 handbrake :cheesy:

Or you've mangled the back plate...

For a rear wheel bearing you'll need a puller and a ma-hassive torque wrench.

could be as darren says, just changed the discs pads and shoes on the rear
one of the reasons being when turning left could hear scraping/grinding
it was one of the shoes :shock:

Urgh. Discs I'm ok with but shoes are black magic to me. I notice this long weekend is going to be rain, rain and more rain too... :cry: If the general consensus is that it's more than likely just the drum then I'll leave it a couple of months until I've been on holiday and had another payday

What's the best way to raise the rear of a saloon?

The shoes aren't a big deal Matt. Disc off, and the shoes are held in place with huge springs. You need some good needle nose pliers or a hefty spring hook to get them off. Other than that it's pretty logical.
I just used a trolley jack to raise the rear on mine, can't remember where I jacked it from though :oops:

No audible difference when the handbrake's yanked half way round a noisy corner, so unless it's the main brake (no noticeable noise there) it's to the garage for a new bearing :(

£66 at GSF. Any ideas how much that'll cost to change at an indy?

My local man changed both the rear bearings on my zook for £80, not including the parts :?

Matt, get it in the air, take the wheel off and give the disk a spin, it's not such a deal to take the disks off to have a squint either (1 hex & one socket head to get the calliper off, swing it out the way and prop it up with something to take the strain off the pipe, then it's two torx screws to get the disk off). My D8's backplates are shot and made out of sheet steel and every time I touch them they scrape on the disks for a while - especially when cornering. It could also be the drum's full of dust or one of the tiny springs that hold the shoes on has rusted away. I'm concerned the garage will only be too happy to take your money, duff bearings or no. Besides, how many posts have you seen on here for duff wheel bearings???

i agree with steve here , its not very often you hear of a wheel bearing going and when they do they usually start of quiet and then get louder over time , its very rare just for them to go all of a sudden and a shot wheel bearing usually makes a humming noise that increases with speed . most garages will take your money and change it even if it dont need doing :?

I had very similar noises on my car some years back and sometimes it went with the handbrake being pulled and sometimes it did not.

I changed the rear shoes and disks - dont forget to wind the shoe spreader adjuster in before having to use a hub puller to get the disk/drum off :oops:

The noise went away immediately, there was nothing obviously wrong with the parts i toook off but the noise went and has not returned.

Wheel bearing............. my car has done 122K on the original bearings, i hope i have not cursed myself now!

Hmm it's a lot worse today, but here's something interesting:

I oversteered into the carpark at work this morning (left hand turn, negative camber, uphill, VERY slippy) and still heard the noise, even while the handbrake was on with the rear wheels locked. I'm now wondering if it's actually my Happy Shopper exhaust hitting the bumper again, although the odd thing with that is it's hitting NS of the bumper so a tight left turn would drag it away... unless it's normally resting on the bumper (would explain the smell...)

Urgh. I shouldn't have bought that bargain basement pile of crap. Anyone know someone that's breaking a V6 with a reasonable eggsauce?
