how hard is it to replace wheel bearings and does anyone have the service info for the rear set? Never done wheel bearings before but im getting a vibration while driving at speed and want to replace them to see if this fixes it.

Are you sure the bearing is worn? Do you have horizontal and vertical play in the wheel when jacked off the ground?
Never done a rear wheel bearing, but I imagine you will need a good size puller, appropriate socket and breaker bar. I'll check the WIS to see what they say

I think there are at least five other bushings in the rear that would go out before bearings and could cause vibrations.

-rear diff bushings(has three)
-rear subframe bushings(has four)
-rear control arm and all the links(at least 4)

Yeah, good thinking

Yea and all of mine need to be done except for the rear control arms. Already have my diff bushings but Im too lazy

Have you checked your flex disc/guibo? those will cause vibration also.

Yup! Just replaced both but still have a vibration.

For those wanting to do a full suspension rebuild which will stiffen and plant the suspension, check out these guys: http://www.strongflexuk.co.uk/mercedes/c/w202.html
You can also upgrade the rear sub-frame bushes. Don't know if you get extra road noise though...

I'm seriously thinking of doing this in my next winter maintenance. Will have to consider getting a extractor to use the original suspension arms

Im so conflicted with poly bushings. At the end of the day for me both luxury and performance are #1 so I try to stick with rubber when I can just because I don't want to hear the squeaks or have a stupid stiff ride
