these two racks have different part numbers - what gives? are they not interchangeable??

 

My understanding is that they are interchangable, but ZF was constantly updating the design. And for good reason, from what I hear.

 

anyone know the reason for the update, then?

 

I have installed these things twice and they all looked a little different. Nothing big though. The pressure lines are routed a little differently and they are connected by an allen head on some and a hex head on others. So that MIGHT explain the discrepencies, I dont know. I am pretty sure the S2 uses a rack that is not interchangeable. I would try and contact ZF somehow if I were you. Sorry I can't really help.

 

The information I have is that all the racks are interchangeable. I don't know the specifics of the changes ZF may have made over the years. The only real differences I've seen is the tie-rod ends (longer on ABS offset cars - 87+) and the use of the updated hex head banjo bolts (you definitely want these over the interior Allen type)

Anywho, the two parts listed are 944.347.011.22 and .24 (early - late). Rebuilts do not specify which you will receive. Also, the na/T/S/S2/968 all use the same.

Good Luck!

 

Someone posted a rebuild for these ..anyone know what the kit is?
