I changed out the gear oil, and added traction modifier fluid to my '82 model 20 rear. I was able to spy the clutches behind the side gears. ( this confirmed the "BB" stamped code on the axle tubes indicating a factory limited slip diff.) My question is: How can I test, or be sure the Trac-Loc is working properly? I performed the following test(Not sure if this is a correct way of testing) I jacked up one side of axle an in. or two and placed trans. in gear assuming jacked wheel would spin and wheel on ground would pull.(jacked wheel spun, wheel on ground did not pull) Then I jacked up other side of axle and did the same. (Jacked wheel spun, wheel on ground did not pull.) I am aware that a limited slip diff. only transfers part of the torque to the wheel that is not spinning, but I thought that the jeep would at least pull somewhat on the floor jack. Am i ding something wrong? Is this the way the limited slip is supposed to behave? Perhaps my clutchs are worn?
Any input will be welcome
PigPen states that with both wheels jacked up one should spin in one direction, and the other wheel in the same direction. Mine spins in the oppisite direction.. Iguess my clutches are worn out. Haynes has no info about replacing the clutches.... now Im wondering if a shade tree mechanic like my self is capable of replacing the clutches nyself. If gear lash and such has to be measured then the job is out of my scope.
Any coments and replys welcome.
