Could be that the front axle brackets are loose on the axle or frame...
Put the front end up on jackstands under the frame, chock the rear wheels 1st, then see if there is any slop F-R in the frt axle assembly.

I would agree with DUB, is the prop shaft tight? If that CV goes, that could be an issue as well. If it is rubbing the exhaust, are your exhaust hangars good? Perhaps the exhaust moved, not the driveline?

well I checked the axle brackets and everything appears to be pretty solid down there. The exhaust is only a few inches from the header so there's no play there at all. and the prop shaft bolts are tight too.
nothing seems to be loose down there but clearly the shaft is moving vertically. I'm thinking that possibly the entire diff is rotating about the axle shaft when under torsional stress, causing the back end and prop shaft to sit higher, but this is a guess. tomorrow I'm going to try to recreate the issue and watch what happens when the tires are lifted off the ground.
What I'm struggling with is, why is there all the tension and whats causing it? is it stuck partly in 4 lo or something?

Did you put the trans in neutral, before shifting to 4-hi?...

Don't just check where the axle housing bolts to the bracket (although that's the most common place they come loose). Also check where the brackets attach to the frame. They attach there using a rubber bushing to allow some 'give'. If that bushing has been damaged, it could allow the axle to move in relation to the exhaust.Originally Posted by Ldub

Also, any time that you've had it in 4L, toss a little terra-firma in reverse once you have it back in TOD. It may not help ... but it don't hurt either. Blue haired 4 wheelers learnt to do that back in the day to ensure that the transfer case fully dis-engages.
