Are you lifted with blocks or springs? Reason being if blocks u could have a crack in one and when backing it could be binding or possibly a broken rear leaf

Did anybody ever think that their u-joints are going bad?? Mine did the same thing and it turned out i had a bad driverside u-joint and the u-joint nearest to the t-case was bad too. Id check them out if i was you.

This could help with you problem.
I kind of have the same problem. I have a all wheel drive... I talked to a transmission mechanic and he explained it like this. you need jack all four tires in the air. run a tape measure around them and write it down if the measurements are off by more than a couple if inches you might have to buy 4 new tires to stop the sound. all thew tires must have the same circumference, Hope this helped

I have a similar repeating "thud" only when backing and I've been told that it is my differential grabbing. Haven"t changed my fluid yet so I can't confirm.
