Check the u-joints in the driveshaft.

Get under the Jeep and grab the rear driveshaft by hand. If you can turn it (slop) than you need a new u-joint in it somewhere.

never really noticed it in mine, I have Spicer ujoints, don't know if they're original or not, but that's what they came with OEM.

But it does sound like Ujoints, replace them both since they're the same age, and it's better than getting stranded!

I wasn't able to check out the drive shaft but I spent lots of time thinking. Here is what I think.

The ujoints are probably the culprit, as indicated above. As the brakes slow the vehicle, it forces the drive shaft to slow - it doesn't want to though as it's naturally spinning via the t-case.  It's putting pressure on the u-joints, which are clearly a bit sloppy, as they are popping as they rotate.

Furthermore, the pressure on the u-joints is probably caused by the increased pinion angle from my sagging leaf springs. Because they are flat, almost inverted, the transfer case is lower and therefore the driveshaft is forced to a non-optimal angle. It's therefore possible that the drive shaft is too long for this angle as the required distance from the axle assembly to the t-case is too short.

Therefore, I need to raise my rear via new leafs and shocks to relieve the pressure. However, because the damage is done on the u-joints, they will have to be switched out as well.

Does this sound logical and reasonable to you guys? Further, does anyone have stock suspension components that can be floated my way for a reasonable price? I'd prefer to go with both front and rear, as she rides like complete crap. Thanks for any help!

PS - I'll double check the d-shaft tonight, I promise!
