Freightliner rear alignment/ hardware

I'm putting the rears back under my truck now and I just had a question.

I did buy new nuts and bolts but I did not buy new wear pads. Do they normally replace bolts nuts and wear pads along with adding shins?

Or do I buy new wear pads and they just replace the shims and the lock nuts?

 

Those bolts had been in there for so long I had a hell of a time getting them out.

The bushings themselves were worn so badly that the center part that bolts up to the hanger was completely separated off the rubber on three of out of four. It's hard to believe those guys let it go that far.

That's great to know about the wear pads because I'll put everything back and they can take care of the shims when they align it.
