Recently the rear wheels on my 89 supra locked up. I thought maybe the brakes froze since the change in weather but after seeing it pulled onto the flatbed and still not break lose im stuck between thinking the rear differential went or something along the lines of the tranny but it still is able to go into gear. Right before they locked it made a horrible grinding sound ive never heard before.

disconnect the driveshaft and try to spin a wheel. it will tell you whether it is the tranny or the rear diff.
Before you even go there... push in the clutch with the car in gear and see if they spin. If so, it's the motor.
If they still don't spin, take it out of gear and try it again. If they spin, it's the tranny.
THEN disconnect the driveshaft...

Didn't mention if he was driving when it locked up. Locking up at 80mph makes for a much more entertaining story.
It makes a big difference knowing if the car was actually moving and if the engine stopped running, and which end of the car made the grinding noise. If you think the brakes froze due to weather then you must not have moved the car more than a few feet. Freezing brakes, I'm from Florida and just the thought of it being that cold gives me the shivers.

Just read this thread and my first thought was no fluid. Because mine only had .5 quart (1 pint) of thick grey substance when I flushed it the day I bought it. The axle seals are the main culprits with the pinion seal being a close 2nd. The thing only holds 1.1 quarts its whole life, not much room for error. I check mine every year, I don't change it anymore because the drain plug threads in the diff are about as soft as the exhaust manifold stud threads in the cylinder head, can you say soft ass aluminum?
The differential casing is definitely good old cast iron. Those threads are made for the plug to be removed on a regular basis as a regular maintenance item.
And that it holds 1 quart is exactly why it should be changed often. More often then what the book says.
isn't dry weight around 85lbs? i switched out my blown diff thursday night and finally installed my LSD. boy was that no fun. 24 total stubborn nuts/bolts IIRC. i forgot what Jose had me use, but it made WD-40 seem like water.
I don't know, but it sure is heavy. Swapped to the open diff out of my parts car so I can rebuild my lsd. Used a trans. jack to get it up in the car.
