Just ordered one for my W211 as the bearing was beginning to make quite a loud noise at speed over 30mph though when car jacked there is no noticeable movement of the tyre when shaken at with hands on 12/6 o'clock position. I did repack them about 3yrs ago so I'm guessing they have run of grease. Question is does this HUB come prepacked with Grease and ready to fit like the OEM Mercedes ones come?
