The boots were full of fluid also so seals are shot.. newer rack was nice and dry but module wires torn off right to the nub..

I will find and post manual shortly..
Essentially rack placed in fixture holding tie rod ends then rubber plug pulled. Drop dial indicator within and move column connector to measure lash. Screw cover int/out..When tolerance range met pin cover with punch. I'm willing to give it a go..

Cool thanks.

Worth a shot swapping parts between the two then since they aren't easy to come by these days. I need to do the same with one of mine too as it turns left better than it turns right so something internal is broken hence my interest in the manual

Well this is not going according to plan.. Got spring swapped over and screwed in cover to to about the same spot as other rack. Appears to not have any slop in the lash when pinned to the bench but have not figured out a way to properly hold the dial indicator to be sure..

Bigger issue: Found a module that was sold as a ZF 7039 442 102 but instead I was shipped a 7039 442 214. This is different in that it has the cylinder shape and the diameter of the outermost seal is too wide for the recess in the rack. Has the correct BMW connector however.

I cannot find a 7039 442 102 to buy anymore, nothing in stock. New ones are insane$ and not available either or wont ship to the states.

Considering machining an adapter to go from the approximately 22mm diameter outer ring to the 15mm on the rack and get on with it.

I can troll the junkyards for a 2000ish 5 or 7 series BMW, an Jag xjs or xj6
to rip one off of? other makes?

Or is there another direction?

Oher part #s I struck out with:
LEMFÖRDER 1063401
ZF 32411134770 BMW 7 series etc...
jaguar JLM12142
