What is the best way to check for a worn out shock bushing?Mike

tried to tighten the spare.... Still no luck. I tried to pry up on the box to see if I could spot any movement but nothing... Any ideas??????Mike.

I tried to tighten the bolts but they wouldn't move. i noticed while pulling my boat the noise didn't seem to be there. Any ideas?

My wife just bought a 2007 F150 Supercrew and we noticed that when hitting bumps on the road, there is a hollow sounding thump from the box area. I also noticed that the box seems to move up and down when hitting these bumps. (movement seems to be on the drivers side). Anyone experience this...
