Right guys ive got a snag with the motor and spoken to hundreds of people who recon my wheel bearing is shot. Its a squeeking noise rather than the standard droaning noise. Anyway ive got the bearing kit, now is there any particularly special way to change it? The only reason i ask is that the kit has come with 2 O-rings, a circlip and a bag of grease. Ive never had to put grease in any of the bearings ive changed so far. Is it different to a normal bearing? I cant find any write-ups on how to do it so just wanted some advice. Including torque setings etc. Its a 2000 Uk turbo. Cheers guys
