Cannot figure out whats making the noise, it only happends at fast speeds over larger bumps in the road, some times i even get multiple knocks, if im going fast.

Could it be the rear diff. mount? a rear suspension component?

sounds like its coming from the rear of the passenger side.

I can feel the bang if my arm is on the armrest....


TIA

Had the same issue a couple years ago; replaced the suspension and control arms and it went away. Never had it fully diagnosed as I had ordered the parts before it started happening and replaced shortly thereafter...

loose suspension bolt, broken sway bar endlink, loose subframe bolt....

Start checking all of it...no good way to e-diagnose this one...you're in the best position to figure it out.

my suspension would flex and the exhaust was tapping against the rear diff, i could feel it in the armrest...of course this was right after i had some CPO warranty work done, dealer fixed it no problem.

Crawl underneath and move the exhaust by hand when its cold, see if it hits anywhere.

Otherwise, check all suspension components.

Worn swaybar bushings are a possibility too. Esp. Urethane ones.
