Thinking about changing or repacking these.

Are special tools needed?

Is this a simple project?

What type of grease to use?

Procedure?

Thanks

Complicated procedure and tool set designed by engineer per WIS; dial gauges, etc. Or use allen wrench along with common sense as you've always done it the past as with any other car.

Take cap off and you'll understand.

Repack with bearing grease, tighten, smack with hammer to release tension and spin rotor to dbl check.

I used a standard high temp/pressure wheel bearing grease to repack mine.

MB prob has their own private label brand sold by the gram.

Mercedes, at least for my older cars, has a very convenient 150gram tube that their wheel bearing grease comes in. I say nice, because the wheel bearings only call for a specific amount of grease, typically about 65 grams for each side. With this tube of grease, it's pretty easy to get just the right amount of grease for the application. Without it, it's pretty easy to over pack the bearings which can cause problems.

It's impossible to overpack bearings, the excess grease just squirts out the other side of the cage. Infact thats how you know they are packed properly and fully.

I am partial to synthetic grease, years ago I had a 280Z racekar that would eat front wheel bearings and spindles on a regular basis. After I tried synthetic the problem went away.

The 150 gram tube works fine unless you have multiple cars that you are working on. Otherwise, it just sits on the shelf waiting to get squished at an inconvenient spot. Ask me how I know. I use lots of dielectric grease so I have a big tube. Things I use rarely, I get as small a tube as possible.

The other thing that hasn't been mentioned is to not mix greases with incompatible soap bases.

If you don't completely clean out the old grease, be sure that you add the same type.

Thanks for the responses.

Are any special tools needed? Don't know why I am afraid of this job, just did the lower control arm bushings and sway bar links two weeks ago, so this should be "simple", just have never done it before and don't want to mess anything up.

No special tools required, and you're right; it's a simple job. Be sure to hang your brake calipers with an old coat hanger or similar. Don't just let them hang by the brake lines.
