Reply With QuoteI have a 9" rearend (in another vehicle of mine) that does NOT have a Tag
or any other ID on it. I was told it was a 3.91 gear set, but I'm not sure.
Can someone explain how to determine what gear set is in it and if it's a
Locker or not.

Put a mark on the tire, and on the driveshaft, or the yoke, and count the
number of revolutions the driveshaft makes to 1 revolution of the tire. The
driveshaft will turn slightly less than 4 turns to one turn of the tire if
they are 3.91's. To check for a locker, with both tires off the ground, turn
one tire, and watch the other one. Both tires should turn in the same
direction. Also, when driving the car, when making a relatively hard turn,
you will hear a clicking noise coming from the rear end. Hope this helps.

Re: 9" Rearend Info needed
Actually, I did do a preliminary check a few weeks ago....
The driveshaft test yield slightly less the (2) Turns of the Driveshaft Vs
(1) Tire rotation. Yes (2). ????
Also, when I turned the one tire, the other didn't move (if I remember
correctly). I'll have to jack the car up again and re-do this test.
As for driving it, it currently has NO drivetrain. :>(

If both tires are off the ground, one will have to be held stationary to
get an accurate rotation. Sounds like an open rear, non posi/locker.

Re: 9" Rearend Info needed
Why would the driveshaft only yield LESS than (2) Full rotations ??
