Product started messing up after only 6 months, started get weak and barely start Jeep every once in a while. I should have returned it then but I didn't. It was a little over a year after I got it when it self destructed (warranty ends at one year, nice huh). The gear that goes into the flywheel totally broke up, and there was nothing left when I took the starter off. Now I have to worry about the missing gear and wonder if it's still in the bellhousing and if it might screw up my clutch or flywheel. This could have been a lemon starter but im not wasting any more time with powermaster. Man it's a crap shoot with auto parts these days, where did all the quality parts go.
