Im in the process right now of switching out my 2.73 factory posi rear end to a 3.42 gears SLP Torsen Posi rear.

I have both rear ends sitting beside each other on the garage floor. My question is,

When I turn an axle on the 87 factory posi both axles turn in the same direction along with the yoke.........but when I turn an axle on the SLP posi they turn in opposite directions and the yoke doesnt move.....but when I turn the yoke on the SLP posi then both axles turn in the same direction....why is that?

is it because the SLP unit is not locked?

I just find that ODD!.......

thanks guys!!!

 

My posi works the same way as your SLP unit. I don't believe your old one was posi, was it?

 

That's normal. Never test for an open rear or posi rear by spinning a wheel. Spin the driveshaft/yoke.

 

speaking of odd rearends, whats the deal with my new ring and pinion bolts, the tighten when you loosen, as in if i where to take a socket and put it in the off position for every other bolt on the planet it will tighten my ring gear bolts and vice versa, is that normal

 

WHEW!! that makes me feel better! I thought something was wrong with the SLP unit.....but I guess not.

Yeah my old rearend was factory posi with 2.73's

 

So they are reverse threaded bolts because they don't want them to come out when the item is rotating mostly in a certain direction

 

that would make perfect sense , on a lighter note go yankees.
