If the halfshaft has trully pushed in the diff, then that would affect camber and also toe. A lot of force is pushing inward or outward on the halfshaft normally, depends on what type of driving is taking place and if something broke at the halfshaft yoke while in a hard turn....it could be an exciting ride!

If the yoke is pushed in the diff, there might not be enough adjustment in the camber rod to make for it.

The yoke should have .0045 in. +- .004 in. end play. It seems like if part of the yoke is wearing into the housing, the clearance would be a lot more, unless it was set wrong at the factory.

Thanks for this. It makes perfect sense, and it was the answer I was afraid of getting.

How hard is it to remove the diff without a porper lift?

Once the diff is off, is it posible to just replace broken ande worn out parts? Or would you suggest replacing the whole diff with a new one?

Last but not least. What is the best source for diff parts?


Thanks!
