Not sure if this is the right area. But I have a Rubi unlimited w/ a Rusty's 2" lift. After this last tire rotation, 24k. I get this intermittant shudder sound coming from the rear and sometimes the front of the vehicle. It happens when I am coasting down and usually below 20 mph. It almost sounds like a loose heat shield vibtation/ shudder/buzz. But all is tight.
Any ideas?
Thanks, Greg
