Thumping Noise....Need Help When I first move my car after sitting for a while, I have a thump noise. I know it is not the u-joints, gear backlash, and tranny yoke because I have checked them and they are good. I do have the stock posi that came with the car. All I have done to the driveline is a RAM clutch/PP and Richmond gear with new bearing and seals. Any input? Could it be motor or tranny mounts broken?

Re: Thumping Noise....Need Help check the tranny mount. It may look like it isn't broke but those rubber mounts will break and the only way to tell is push up on the rear of the tranny and see if the rubber is still attached or if the bottom half stays there and the top half goes up. You should feel the gear shifter go up when you accelerate if it is the mount and thus thump or bang against the bottom of the car.
