Is it only when you go in reverse?

 

 

 

Did they not tighten the axle nut? That could do it. Is it just the brake pads shifting? Somebody needs to have a look. It could be so many things, take it back to whoever put your axles in and have them look. It may be something very simple.

 

Les shwab put them in and I took it back and they checked them and the brakes they put it on the lift and said "i think it's in the transmission"
