Hi Brad, I had to replace the straight controller arm just after 3 months put them on by my mechanic (Dorman), Bushing busted by the frame. You mention the XL MAS lower balt joint. I removed the arm out of the balt joint, and while i put the arm back i'm not sure where the washer suppose to go. Do you recall where the washer suppose to go? I installed just right below the bolt. Should it go there or above the coin. Thanks.
