[QUOTE="frank700, post: 10535484, member: 87323"] Hi guys, I picked up an 03 10th annv. a few weeks ago. Awesome car but had a very loud thumping banging noise coming from the rear end. It happened when you engage the clutch and power was transferred to the rear end. It was loud and you could feel it through the floor. I searched and went through all the posts on this message board about the problem. Didn't seem like there was a sure fix. I jacked the rear of the car up. I removed the stock exhaust system yesterday to install a Magnaflow. I noticed all the backlash in the driveline. Not sure how many degrees it is on the driveshaft but seems to be excessive. I moved the square metal weight around that hangs below the front of the pumpkin. It moved rather easily. It also moved the whole pumpkin. I looked at the rubber bushing that are on the front of the pumpkin and noticed it was easy to create space between the rubber and the metal that is sandwitched on the front of the pumpkin. I am speaking about the two bolts that go straight up and hold the front of the pumpkin and the square weight hanger. I attempted to tighten these two bolts. They were as tight as they could be. So I needed something to shim theses bushings that are to soft and worn out. I went to the hardware store and purchased two 3/4 inch washers. $2.60. I took a grinder and cut a slit out of the washer so I would be able to hammer it in between were the rubber meets the aluminum on the housing. I rotated the pumpkin forward to create the space needed to begin to insert the washer. I hammered one washer in on each side. They fit well. Finished exhaust. Test time. Started car put it in first gear. Nothing. I went forward and reverse. Nothing. Went out for a 15 mile drive. Not a sound. So long story short because of the rubber mounting bushing on the front of the differential being wore out and probably to soft is causing to much play, slack causing the noise. I know it may be hard to understand without pictures. Sorry. But this is no doubt causing some of the noise related problems in these cars. Hope this is of some help. Take care [/QUOTE]
