Does my Dana 44 does it have Tru Trac?

Hello! I am new to this Jeep Forum I have a 1976 Jeep Wagoneer with a 360 Quadra-trac. When I pulled her out of storage this year I noticed the rear diff was leaking, I am unsure if I have the Truetrac rear end as from my understanding would require Limited Slip additive. The Tag# 5356009 46-13 3.54. I believe it to be the Dana 44 Rear end.

If it does, there should be another tag on the axle saying so.
It probably is not, but someone could have switched it at some point, and not put the tag on. I'd say open it up and see. Very easy to see the difference once you open the diff.

I did have it open, and it appeared to have spider gears, that would mean it is not the True trac correct? I also assume it does not have Truetrac, I am not familiar with rear ends, and advise would be great thanks!

The Detroit truetrac uses standard gear oil, no additive needed. If you see spider gears, it's not a Truetrac . Didn't jeep call the OEM a tracloc?

If it looks like this inside your cover then you have somekind of locker/truetrac.. If it doesn't look like this, then you have spider gears..

Thank you! I do NOT have a "Trac-Loc" then. I appreciate the help. No Friction additive needed. New to the forum!

I've got a tracloc or whatever it's called from a 79 chief in mine. The open had a tapered housing for the spider gears, whereas the tracloc had a squared off case, like the locker, but with visible gears inside.

Quick way to tell jack up rear spin tires if you spin one tire foward and the other rotates backwards= open rear end.

And if the opposite side does nothing?

Is the drive shaft turning?
If both tires are off the ground, spin one, if the other tire does not move, and the drive shaft does not move. Then you have something broken in the rear end (spider gear, clutch, axle shaft)

Nothing broke. Just happened to have it up on stands and spun the right rear tire. Im used to seeing the opposite side turn the other direction but this thing does not. In the gravel both tires spin. Im gunna look at the tag when it gets light out. I should add I just recently bought this rig two weeks ago not running. Tune up new battery and a carb rebuild and we were driving. Still needs work as with everything I own.

My trac loc hardly moves before the other side spins, maybe an inch at the tread surface. Even then the drive shaft begins to spin and stops in park.
The rotation of the tire has to have a counter action in the drive line.

Correct. Put Trans in park or in 1st if manual. if its an open rear the tires will rotate opposite each other. If same direction its an LSD. If other tire does nothing then likely its a shot LSD and needs new clutches. Assuming its not major part failure as Rock mentioned.
