I bought a 2003 Suburban and have noticed something recently-When I am coasting (foot of the gas and brake) around 15-20 mph like through a subdivision and then step back on the gas I get a clunk from the rear of the vehicle. When I baby the gas pedal, no clunk, but if I give it pretty good gas, (not nailing the gas) the clunk is there every time. U-joints were just replaced and the clunk is still there.
