Anyone else experience a loud THUNK from their MY rear suspension when going over bumps/bumpy roads. It's jarring. It's almost like there's a big book in the right rear trunk area, that slams down when you hit a bump. Is it just the stiff as hell suspension and my crappy rutty roads? I also do have the MPP lift kit - would that affect how the suspension behaves over bumps? Any help is greatly appreciated.
