I got the axle out of a 2wd pick up. It looked just like a 10 bolt, but it had sensor wire coming out of the top.
Production date of the Trooper is May '87.

Tire size is 33x12.50. The sad part about this whole event is that I wasn't even "gettin' it" yet. I had just locked the hubs and was starting toward the first hill climb. Flat hard dirt with hardly any traction. I think the axle was starting to break prior to it breaking all the way. I took the kids for a ride up and down the street a few times while I only had about 10 lbs in the tires. We were barking alot around corners. Now that its fixed, I'm not driving it on the street till I put some air in the tires.

I hope I answered all yer questions.

Peace out!
