They are made of rubber so it's very common for them to go out. It's the bearing on your driveshaft. A replacement bearing will cost about $80 and you have to a shop press it on for you..or you can opt for a one piece drive shaft. If you still have the shifter mount I'd be happy to take it off of your hands :)..one of the last pieces I need for my auto
