89 300se rear wheel bearings
 

need a little help on rear wheel bearing replacement on my 89 300se,seems pretty straight forward ,but i haven't taken the time to tear into it yet,i need some good info on procedure if anybody's willing i will take whatever advice i can get,they are not noisy but close to 300,000 miles on them,just got done with fronts,they were very easy,time to tackle the rears now.

Rear wheel bearings are nowhere close to the fronts. You need to remove the large axle nut (200+ ft lbs), and then usually a special tool is needed to pull the old bearing out of the wheel carrier/hub. And then another to press the new bearing in straight.

If mine ever go bad, I am taking it to a shop. Or maybe buying new wheel carrier hubs and having the bearings pressed in outside the car, then just swap out wheel carriers. If yours are not noisy yet, I would leave them alone, honestly. I would spend the $$ and time on something else. Just thinking about the job makes me shudder. :D

Not noisy = do not touch. Rear bearings are an involved process and not for those without all the special tools to be doing. I think I'd be glad they are running quiet and leave them alone!

The rear bearing on that car has a crush sleeve to set the preload. Even with the proper tools and know how the success rate of replacement isnt too high. Do not replace unless absolutely necessary.
