At that mileage it might be a good idea to replace the bearing and both guibo's since the labor is the same and the parts are cheap.

If you haven't replaced your motor/trans mounts I would do those too.

My passenger side motor mount was shot @ 90k miles on my 330i, I replaced both with the upgraded 335is one see my thread. This only gave me vibrations at idle.

Trans mounts are like $17 a piece are are easy as pie to replace.
