Shuddering in back on bumps

[Robert Sayre]

I seem to be getting some residual shuddering or shaking coming from the rear when going over bumps. Anybody else experience this, and if so what did it end up being the cause of it? Thoughts I've got are the factory hard tonneau, but that wouldn't cause this kind of side-to-side shuddering. Maybe body bushings are worn, loose, or just soft? Or maybe it's just the truck wiggling on it's tires, tires flexing? Our escape which is bone stock doesn't do it, neither does my ranger, which has 60 series tires. Not sure what series of tire is on there, I think they're the wrangler. Maybe it's a softer, more flexible sidewall tire?

The oem ST shocks stink. Also check your tire pressure, I run 36 all around, Another thing is check your sway bar, the bolts have been known to loosen up.



ALSO the ST frame is super flexable, So a trailer hitch bolted in the back will help.
