[DeTomaso] How much "Play" is Normal In Rear Drive

[Joseph F. Byrd, Jr.]

To me, measuring the accumulated clearances and backlashes at their radius
(rx) using the extended radius at the wheel/tire (R) should have an
acceptable amount.

(R/r1) X ujoints + (R/r2) X splines + (R/r3) X differential X (R/r4) X
selected gear = wheel rotation 

Now to define all those variables to see if 1" would be expected :)

Joe

BTW
I case you haven't seen this elsewhere.   A nice bike ride from Helsinki to
Espoo.   Skip the first 9:00, then turn up the volume and hang on for the
next 20 minutes.
This rivals anything in a movie/TV

Dear Chuck,


                I am not an expert on ZFs, but I have noticed the phenomenon
that you observed in both of my normally functioning ZFs.  I think that
"they all do that".


                               Warmest regards,  Chuck Engles
