76 1/2 Ton 4" Lift Spring Centering Pin Not Centered

[splehigh]

Wondering if anyone else has had this problem with Rough Country 4" rear lift springs and what they did to fix the problem.

Ever since I installed the springs the rear of the truck dog legs to the left. After a while I took the springs off to check them out and the left side centering pin was broken. I replaced that but the axel still sits about an inch forward on the right spring. I can see just by looking in my mirror while going down the road that the rear is to the left. When looking at the passenger side fender you can tell that the wheel sits more forward then the left side.

Is it possible that the springs were drilled wrong? I cant see any other reason why this would happen. Everything else seems to be fine.

Thanks!
