Need some help with wheel bearings on my 91 300E. Seems my front wheel bearings loosen within 1000 miles after adjustment. Someone explain to me what I am doing wrong or how to do right. I have repacked wheel bearings and replaced wheel bearings using the procedure in the manual. No matter if I repack or replace, seems the bearings loosen within 1000 miles or less. When I say loosen, I grab the at the top and push/pull vigorously. I can feel movement and hear 'clunk'. I purchased and used a metric dial indicator the last time and tightened to an indicated .02mm. Everything seemed fine for about 750 miles and when I re-checked, loose again. Talking with the local MB techs, seems i may not be tightening the bearings enough on the initial setting. The manual states to tighten bearings until they turn "with effort", loosen and then tighten to .02mm. The MB techs @ the dealership dont use the dial gauge and they say that they have no problems with come backs. Is this true or does every 124 out there have loose bearings?
Any help or suggestions would be appreciated. I have replaced all tie rods, drag link and rebuilt the idler arm. The front end is tight enough that the loose wheel bearings can be felt.
