I'm starting to give up on this machine. I need a new half shaft on the rear called many places and mine is completely different from the ones they offer. i'm trying to avoid case directly if I can. The part number is 8603690 it measures a 1 5/8. Mine on the other hand measures a 1 3/8 on one side and a 1 5/8 on the other. Its not a straight shaft either it tapers. I've tried almost every where and I keep going backwards.
Strangely the parts book drawing distinctly shows the taper on the inner end.
I am pretty sure it is a ZF axle assembly. There should be a ZF ID plate on the housing somewhere...……...get those numbers and call a ZF distributor and they can usually get you a parts breakdown with ZF part numbers.
