My rear left A-arm has a lot of slop at the hinge-pin while the rear right A-arm is fine. The rear bearing carriers have a lot of slop as well, both sides. I double-checked the assembly manual and made sure that I used all of the spacers. When I disassembled the rear A-arms and put them back together, I found the rear bumper caused the slop.. any advice??
