When setting preload, I do it with the wheel mounted. You can wrap the wheel with your hand and the resonance will change exactly when the preload is correct. I read this technique was used by a German mechanic. When I tried it on my 124 and compared with a dial indicator, it was spot on! With the preload correct the bearings look new when taken out for servicing or some other repair. When too tight, the rollers seem to turn brown.

The dial indicator is for precision. I have always done them the same way I did detriot iron. Over many 100s of thousands of miles, I have never had a problem, and never used a dial indicator. But I don't run on a track either. Just on ordinary American roads. If you run on European roads, you may need the precision more. (or roads in most of the rest of the world.) Ever seen the narrow roads, sheer cliffs with no railings and tight switchbacks? After driving my old 190Dc, a detriot car of the 70s feels like herding sheep. Fortunately Detriot iron has gotten better. My 84 Escort Diesel had rock and pinion and handled well. >Dieselhead <126die...@gmail.com> writes: > >> I have not had to replace a wheel bearing on a 126, or 124, but on the >> older MBs, the bearings were the same as a plymouth, Dodge or >> Chrysler, and I think ford also....
