Diff change help
I have just changed fom a 7 inch diff to a 4.27 7.5. The chassis mount has been altered to suit . I have removed the diff flanges so i can fit my drum
braked shafts.The shafts are 8mm to long on the passenger side and 6mm driver side.
Everything bolts up okay, and turns freely,with plenty of movement left in the joints when raising and lowering the suspension .My question is will
running the driveshafts in compression put pressure on the diff bearings and wreck my diff what do we think?

Don't think that it would be problems, because if you move the suspension and everything turns properly without sounds.
But I prefer to check it visual.
To do that you can remove the diff rear cover and raise the suspension till the drive shaft is 100% inline with the diff, [that is the moment when the
shaft is the longest]
At this moment you need to check how close it the shaft inside the diff and that has some play with the gears central pin.
If that is OK than it should be 100%
[The wheel nut should be fixed to have a proper check of shaft length]
Always check at the shaft in-line [horizontal] position.

It shouldn't be a problem, we used to interchange 7 and 71/2 diffs in my race car without any difficulty, they were under a lot more stress than
you will cause in 7 and we never had a problem.
