output shaft from diffs gets wobbly.

[Nigel]

ok thanks guys.

i did pretty much the same thing you did RC John but it still wobbles up and down on the front/rear there is no side to side movement tho so i think its nothing serious to worry about.

i think i will just keep it how it is for now and if i every have any diff tooth breaking problems then i will try shortening the end of part 1 even more and try to clamp it down more.

I just rebuilt my front diff and found the input shaft had a tiny bit of play which wasn't there before. Tried shortening the shaft more, but it didn't help. What I found was I had to length the flat spot a bit using a dremel. After that, I was able to clamp the input shaft assemebly tightly on the bearings. Actually, I got it so tight the bearings felt notchy so I re-did it with a bit less pressure.
I originally only lengthened the flat spot on my rear diff because the front seemed ok. But since I've had to do both my diffs now, I'd say it seems the flat spot cut on the shaft from factory is just too short and so it doesn't allow enough adjustment to clamp the bearings tight enough to get rid of the play.

ok i will be sure to try that when i next take apart my diffs
