James’ 1974 W200 build

I noticed in the fifth picture you had a dial indicator? Was there a spec you were looking for? And on which part was that?.. or parts?... Did the kit come with shims?
**** I think we was measuring the rear axle output shaft preload. And the shitty thing is, is that in order to check the preload or change the preload you had to damn near fully assemble the Motherfucker, and then take it all back apart.

ya also gotta check the idler gear bearing endplay.
