[Rovernet] play in 3500s differential

[LANCE LA CERTE PSY D]

Peter, since I just completed the exact job you're undertaking, I can 2nd Vern's response that the 'play' you have is acceptable.  I had a really bad 'clunk' but it was only at slow speeds, usually when the car was coming to a stop.  Turned out it indeed was a bad u-joint.   The bad news; the other 'clunk' from engaging the transmission never went away.   I remember we've had this conversation several times on Rovernet, and apparently that clunk is almost a badge of honor with that atrocious BW35.  I've never been able to eliminate it, even after having the tranny completely rebuilt and then replacing all of the u-joints along the entire drive line.
Best wishes,   Lance

> I’m in the middle of replacing half shaft u-joints in the 3500s, and replacing seals and gaiter on the Dedion tube, and I noticed that there is a lot of free play in the differential when I rotate the road wheel back and forth. A “blank space” before engaging. How much play is normal, and what’s the best way to measure this? I made a set of marks on the outer edge of the brake disc, and measured 3/4” of “blank space” when I move the wheel back and forth. I have no idea if that’s a meaningful measurement, but it’s a place to start the conversation.
