[DeTomaso] ZF gear oil

[John Taphorn]

No, you will need to remove the ZF as the side plates need to come off.  As 
I recall, it task is not minor the first go around and you will benefit from 
a press.  I believe I made a couple specialized fixtures to disassemble 
those axle assemblies.  Be careful with the spacers, they need to go back 
the same as they set crown to pinion spacing.
