AWD screwed?

[4gfun]

My AWD is behaving in a manner that I wouldn't expect.

The wheels are off of the car, and it is completely up in the air supported by jackstands.

When I started off in first gear, only the right front axle would turn along with the left rear axle.

The ABS light then came on.

I disconnected the battery for 30 seconds and tapped the right rear rotor edge with a mallet to free it up.

Then both rears would turn but not the left front.

I shut the car off and wiggled the left front axle which seemed to be a bit stuck like the right rear was.

The left front is kind of "pulsing" but not moving nearly as quick as the other wheels at all.

The ABS light came on quickly again.

I could have sworn that all 4 moved just fine last time I did this when I put the vehicle on jackstands about 3 months ago.

Rear is a 3 bolt LSD.

It has been raining alot, the rotors and the rotors are rusty as heck since my carport leaks.

Thanks

It's probably the brakes sticking, or worse you blew a diff or transfer case.

Are the brakes more powerful than the driveline?

I hope you are right!

Thanks for the idea.

...but if the front diff is open, shouldn't one side just sit there?

wouldn't you need a welded diff in order for all the wheels to spin?

I think that you would need a welded center diff to spin the front two.

The rear 2 would be spun by an LSD.

First thing I would do is take a scotch brite pad and get off the rust on the rotors, good starting point.

On a open diff one side should go forward and the other backwards, at least most of the time sometimes the other tire doesn't move much. But with a LSD both tires should spin the same direction.
