I swapped rear end on my 94 z71 . I put a 96 tahoe 4x4 rear end in it . All new brake hardware shoes everything new with rear brake. The problem is the brakes keep self adjusting out and making the shoe stick against the drums. I have replaced everything new twice and have the same problem. Any suggestions?

 

Sounds like you're using the wrong Shoes.
Mic the Drum and verify that the Shoes are of the same Diameter.
You may already know this, but short shoes to the Front
