Hello, There has been lots of discussions re investigating backlash in drive train components, but have not found any pass fail criteria advice.
I have the same clunk some people complain about when the auto transmission catches up sometimes especially when braking down past 40km/hr.
I took it to auto box specialist and a differential specialist and a few mechanics, none were prepared to advise what is causing the problem without stripping everything down. The auto expert said its still moving up and down the gears very nicely, and did not recommend refurbishing the box.
The diff specialist said he does not think I will see any real value in re-building the diffs.
I did put heavy duty splined drive nuts on the front just in case its in the stub axles splines, but found no wear there.
So I decided to measure the angles myself this morning, as follows:
REAR: With hand brake on, 3.2 degrees movement.
FRONT: With hand brake on and auto in park, 8 degrees through CV and diff.
FRONT: With hand brake on and auto in park, 9.6 degrees through transfer case.
Total for FRONT is 17.6 degrees.
Is this a lot? I have no idea?
