Hello I am asking this beacuse I can't seem to find a solution for the problem . I have a 2002 dodge ram 3500 4x4 6 speed man. NO mods but for a Banks single stage computer. The rear end keeps shifting. I also have broken the factory block once. Tried new u bolts did not help. The frame checks ok so do all the specs on mounting points for the rear. I wanted to know if any one eles had a problem and what they did to fix it. Thank You

 

have you checked the bolts in the leaf springs holding the packs together? They can break.

 

the bolt is called a center bolt, they are known to break, and if you have replaced the U bolts they will need to be tightened again after a few hundred miles.

 

I have checked the center pin it is good. Also have retightened the u bolts and still have the problem.

 

Have you checked the shackles, shackle to frame mounts or the bushings in the spring eyes?

 

Yes I have checked every thing in the rear of the truck it is all in great shape. I have taken it apart and put it all back to make sure nothing was broken or in bad shape. It has broken the drivers side block now. replced the block but it keeps shifting and wanting to spit the block out of the rear.

 

Seems like you need heavy blocks and oversized U bolts. Perhaps some type of traction bars. You must really be putting coal through engine to accomplish

 

weld the block to the spring perch. It isn't the best fix but I have seen it done more than once.
