1993 300D wheel bearings

[Drago]

would this be the same procedure for my 93 300D?

Yes it would, even valid for W210, W211, W202 etc. Simple design. Dont worry about using special grease - get some disc brake wheel bearing grease and pack it up.

Be sure to use high temp grease to pack/repack the bearings.

If you have never re-packed Wheel Bearing perhaps there is a site that can tell you how or someone here can.

I've done Fords Chevys and Dodges, I'm asking because, well, MBs have proven to me they are different.

Mines not different.

I thought I could adjust the Front Wheel Bearing End Play by Hand as I had done on all of My own Vheicles since 1968 and ended up overheat the Grease because I got the adjustment too tight. So in this particular case My past experience got Me into trouble and created more work for Me by having to do the job over again with new Grease.

Since then I have used the Dial Indicator as is in the Manual and never again had any issue with it.

Then there is My Father who if He hears I am working on a Car always always reminds Me to make sure the Car us Jacked up and supported safely and never fails to mention that someone gets crushed under their Car frequently even though He knows I started DIYing My Cars 46 Years ago and worked and alsow worked as Diesel Mechanic.
So I understand Good but unwanted Advice.

repacking the bearings is easy work, adjusting them too, take a flat screwdriver and tighten the jam nut with the screwdriver - make sure the disc is not attached to the hub, it makes it very heavy.

rotate the hub and screw and unscrew the nut till it repeatedly stops in one place, you can assume it zero clearance. Now try that with your fingers only, you will see the nut stops a little before the point where the screwdriver could move it to. tighten the allen screw and you are set.

No problems with that technique if you are accustomed to repacking bearings, for grease any grease sold in autozone/orielly/napa/xlparts/walmart etc that says good for disc brake bearings will work, mostly american greases for disc brakes are red tinted, MB are obtuse and tinted theirs green.

The american stuff works similar to the german stuff. if you want to eyeball the quantity then you need slightly more than 1/8 of a grease cartridge per hub.

I went ahead got the MB grease, it's probably no different than any other wheel bearing grease but I don't want to take any chances. looks easy enough to do just didn't want any surprises like needing like a left handed universal wrench that only works in moonlight...

You need a high precision dial indicator to correctly set the play (between 0.01mm and 0.02mm or roughly between 0.004 in and 0.008 in) for the bearing. Too much or too little play will reduce the life quickly. One tube of the MB bearing grease will be just enough to do both sides.

the MB grease is pretty pricey for a 150 gm tube, you can buy a 400 gm tube of it too, its actually FUCHS renolit LX-PEP2.

nothing special, plain old disc brake wheel bearing grease of mineral base stocks. Its pretty much the same setup as the old chevys and fords - just the locknut is "germanised" instead of the old american/japanese cotter pin setup.

speaking of moonlight - do you have a black light source, it would be cool to see this grease in black light.
