Need help rumbling sound!!
Hello I need some help here.. I've got a 2005 cadillac srx all wheel drive.. I have been having a rumbling/grinding noise in the rear end of the car.. Its not constant it happens between 45-60mph.. I cant seem to narrow it down.. Now here's the bad part this is a list of all the things I replaced Drive shafts, rear differential, rear differential bushings and cv shafts.. I've done the test for the rear wheel hubs but I dont have any play in the wheels.. I'm close to pulling my hair out here anybody else run across this problem and or have any other ideas?
