I have a thumping noise in the rear of my truck. Replaced rear breaks, drums, front brakes, rotors, c-v axles, carrier bearing, then complete driveshaft. Replaced ALL oil it was all clean. Put truck on jackstands and still makes noise. The noise gets loud about 45 mph and quiets down above 75 mph. I don't want to waste more $ until i have some more ideas. It does have the upgraded 4.10 limited slip rear end. Thanks.
