Overhaul seals kits commonly available.
Try our forum sponser.

Before you start...put a dab of 'White Out' on the steering coupler/box shaft for reassembly orientation....remove power steering lines....C clip on Pitman shaft in front of nut.

Needs a puller for the pitman arm..look for notch on Pitman shaft for Pitman arm alignment.....notch should be in center of parting joint on Pitman arm.......socket head tool for steering coupler lower socket bolt.....leave coupler on upper shaft.....3 mounting bolts through chassis member......Remove the box to the bench....

Pull box apart you'll need seal puller and pick for o rings.
Leaks are common and seal kit will cure that.

Athough you might have wear in box....usual problems are weak steering damper...worn tie rod joints and/or worn intermediate steering arm bushings that cause play/slack.

MB says 1 inch of free play allowable at steering wheel rim.

You need to have MB align the steering or a shop that knows correct proceedure.

FYI...Pitman shaft nut tightens to 50 Nm with Loctite on threads.
