I recently replaced the U joints on my 89 GT and it is still has a slight vibration at above 70 mph. Someone told me that the tailshaft bushing might be worn out. And also, when I looked underneath the car, the tailshaft seal seems to be a little worn out too because there is a fluid leak at the seal. I've been told that you will need a special tool to remove/replace the bushing and the seal. Did anybody replaced this before? Does anybody know a good shop where I can bring my car to replace this?
