Front axle slipping?

New to 4Runners. I've had a few older Jeeps and 2 Cherokees a Chevy and a Ford and I had an 86 Toy Truck many years ago. I picked up a 93 V6, Auto, loaded with fairly low miles this week and look forward to playing in the dirt with it.

After cleaning and changing the vitals, I took it to the wall test I used for my last Jeep. The wall is just a bit low than the front bumper and usually I can drive a wheel up to test the system. Well when I tried it on the 4Runner, the front axle acted as though it had a LSD in it but what was most interesting, is there were moments when you could hear the slipping with neither wheel turning, then the wheel with least traction would slip. It seemed like the AWD Jeeps that allowed for slipping in the transfer case but this sounded as though it was from the front axle.

I've done some research on the web and can't seem to find anything that explains this so I thought I would check with the experts over here. Am I imagining something or is there some sort of a clutching system that will allow the diff to briefly slip if both axles area stuck?

Thx in advance, new to the Toy but want to play with them again. My 86 Toy crawled over everything and I never experienced this .

There's no clutch in there in a stock setup, no. I'm not up to speed on exactly how clutch type limited slips work, but I don't think they can slip such that neither wheel turns, anyway. I don't think, anyway, that seems like it'd be a poor design.

When you say "heard the slipping with neither wheel turning", what exactly did you hear? I'm thinking you might have a burned up ring and pinion, or maybe a bad output in the tcase.
 
okay, figured it out. Took the 4R out to a local field with hills and realized what we were hearing was the anit-lock brakes. Okay, so its a bit more sophisticated than what I've used in the past. Removed the fuse and I have a poor-man's LSD. Thanks for the advice above. May be looking at the different lockers down the road but for now, I'll enjoy and get yanked over or out when stuck.
