If you have time, please reference the following:
Towards the bottom of the thread you say " On early cars the bearing pre-load is important & critical!!!. On later cars, rotors can be done w/out touching the bearings".
My vehicle is a 1991 300-SEL.
Searching through the archives here it sounds as though I'll need a dial indicator to set bearing preload on the front wheels vs. the "fish scale" approach used on other vehicles.
It sounds like rear wheel bearing removal/repack/etc. is out of reach for DIYERS for a number of reasons to include mega$$$ gear I wouldn't have access to.
In my case, is rear-wheel rotor removal/replacement within the reach of a DIYER whose done brake work on other cars?
Thanks for your time.
