I know it's no good but this past weekend my car was so loose the car would break loose and spin at almost every turn, finally after doing everything I could think of I took out my spec r gear diff and opened it up and it was pretty much empty( no oil) so I put the upro one in and it was night and day.. Most likely ill never use it again but I learned my lesson by not keeping up with maintenance.. I pretty much changed and rebuilt everything I can since Saturday
