I just got a 2007 Tundra double cab TRD and I love it. BUT, driving on some LA and Orange county freeways the rear end is very bouncy, to the point of uncomfortable ride. I've had many trucks before, and this is the worse by far. I caulk this up to very stiff rear suspension in the TRD package. But besides running sandbags in the rear is there anything else I can do to stop this. Its pretty embarrasing when I have clients in the truck. I was thinking about putting Rancho 9000's on and running them very soft. Would this solve the problem. I'd apprieciate any help. Thanks!
