I have been chasing a torque bind problem for a few months now and as usual I found the problem in the very last place I could look. I need help finding a MPT clutch hub or some compatible replacement. Seems like they just don't exist. I had a very hard time even finding out what it was called (Ive heard about 30 different names). Am I destined to spend hours at the j-yard pulling a whole transmission for this part or is there a better way? PLEASE HELP!!!!! Thanks!!!!
