The front isn't so bad if all you need to do is renew the seal. You do need to properly crush the new spacer, but basically you set it to where it was when you took it apart.
It is replacing the pinion shaft that is a royal pain on any final drive. I have never done it on a Benz, but it is a multi-step process. First you must get the carrier bearings set without the pinion in place by adding or removing shims, then install the pinion without the carrier so you can measure the projection. Set the projection of the pinion by adding or removing shims, set the crush sleeve by torquing the nut, then set the ring gear lash by transferring carrier bearing shims from side to side. I do not really want to have to do that job again.
