Looking for ideas. I have a dull rattle coming from the rear of my truck. Trailer hitch is removed, and I can't find anything loose anywhere. It sounds like bad sway bar end links, but in the baback.i had it in a local shop for oil change and tire rotation. They try to blame it on my roadmaster active suspension, but there's so much tension on that thing that I find it almost impossible that it could be rattling. Any ideas?

 

Worn shock bushings? Also, check the torque on the bolts for the Roadmaster

 

Yeah, I'll check the shocks. They're only a year old Bilsteins though. But I guess you never can tell with Illinois roads
