My car developed a nasty buzz and vibration over the last few weeks that's road speed dependant and only there when turning left. "Ahha, that'll be the front right wheel bearing then" I thought. So, off I go, embarking on the absolute mare of a job that is changing the hub assembly on an E39. I get it all buttoned back up and..... buzz and vibration still there. "So...", thinks I "It must be the rear right wheel bearing then". Out comes the 3 tonne jack and up goes the back of the car. Off come the wheels and I start spinning the rear hubs... "Hmmm, no play". Now, at this point I'm completely stumped and just as a complete shot in the dark, I jack the front left up, whip the wheel off and spin the disc. NOTCHY AS HELL! Now, I'm happy to have found the problem but have any of you had a wheel bearing fail in such a way that the tell tail noise associated with a bearing failure is only heared when turning in to the side of the failed bearing? Well, it's a first for me. I've replaced countless bearing on countless different cars and I've never heared one make a louder noise when turning towards the failed bearing. It just makes no sense. The inside wheel is loaded less than the outside wheel. Oh well, I guess these E39s are just wierd.
