'09 H3 Hummer rear end vibrating?

AdamEL · 11-07-2013, 08:59 PM

Hey guys,

I'm taking my wife's 2009 H3 Hummer in for service tomorrow. There's a rattle coming from the back end when you let off the gas or step on the brake if you're going 40mph or more. Anybody have any good educated guesses what it might be?

We bought the truck used last year. It has a 2" lift and bigger off-road tires on it. Also has an exhaust upgrade and CAI, but I doubt that has anything to do with the rattle. That's obviously suspension or tire related.

Any help would be appreciated, thanks!
