Since my X is a 4x2-I never gave much thought to the following. I assume my X has a limited slip differential--although not 100% certain as I bought it with 18K miles on it almost 4 years ago. We were up in the mountains and going up this really steep and hairpin curved road. I would have to make a tight turn going up a significant incline--of course the inside part of the curve was lower horizontally and I am going about 5 mph around these things. When they really started getting steep, The X kept going but the rear vibrated like hell. Felt like a bad torque convertor I had in a 94 crown vic except as soon as we were off the steep grade--it quit. I have no experience per se with a limited slip diff but would it react this way????--or????
Thanks

Limited slip differentials have clutches in them which provides a very smooth engaging/disengaging effect. I believe that most 4x2's do not have limited slip as a standard option. It's not uncommon for an axle/tire to hop in poor traction situations...if I'm picturing your situation correctly. This happens quite often to offroad vehicles when traversing uneven terrain. I would not worry about it if I were you.
The next time you have the rear of your Excursion jacked up where both wheels are off the ground, you can easily test to see if you have a limited slip in the rear. Spin one of the rear wheels. If you have limited slip, then the other rear wheel will rotate in the same direction. If you have an open differential (no limited slip), then the other wheel will rotate in the opposite direction.
Hope this helps!
