I am going to change one of my front hubs, but I can't figure out which one needs it. I have all of the classic signs of a bad bearing (hum @40-60 Mph, car wanders a bit) and the noise goes away when making right turns. That would tell me that the right bearing is shot, correct?
Shaking the wheel doesn't tell me much (both sides) as they aren't loose.
BTW this is on a 1993 Deville w/ the JM4/4w ABS system
I prefer to always give specific answers to specific questions, but I want to suggest that it's best to do both sides, as they wear so much the same, (i.e.), they age. If one side is due, the other is too. Also it saves getting the same tools etc. out twice, and going through the same process. The bearings come with the races, so the expense isn't so great. Inner seals need replacing. Napa has a very good high-temp red wheel grease for about $4 per can, which is plenty for the front job.
