Wheel lockup could occur:
 
1. If brakes in applied position.
2. If e-brake cable was engaged.
3. If gearing in the transfer case was broken/damaged.
4. If gearing in the differential was broken damaged. However, this would more than likely cause a free spin. Open the differential and tell - you'll know if they're damaged or not.
 
The impact could have damaged the t-case and the gears inside to the point that the rear driveshaft would not turn. If you put the t-case in neutral (if even possible now) and the rear tires will turn, your problem IS the t-case. If in t-case neutral, one or both axles do not turn, your issues are with the axles/gears or possibly a bent axle shaft.
 
Leaf springs are the ones like you see on the back of older pickups. Coil springs are like your friendly neighborhood Slinky, but stiffer.
 
A passenger front side impact could skew the axle to the drivers side and cause the driveshaft to grenade the transfer case, just as Mac said. If that is the case, that could explain why the back wheels may not have turned unless it was in t-case neutral.
 
Do you have any pics of the point of impact or underside you could post or email?
 
Personally, I would recommend the following (keep in mind I do NOT know what all has been done).
1. Get it to a shop you TRUST via flatbed.
2. Have the frame examined and ensure it is straight and okay.
3. Evaluate the point of impact for body damage.
4. Evaluate the point of impact for suspension damage (springs, arms, axle tubes, hubs, knuckles, etc.
5. Evaluate the driveshaft and u-joints.
6. Evaluate the t-case where the driveshafts come in and then evaluate the t-case itself.
7. Evaluate the rear driveshaft, u-joints, and rear axle for issues.
 
Part of the evaluation should be an inspection of the innerworkings of the axles, differentials, and transfer case. If the t-case is bad, you can put in a remanufactured t-case and it will bolt right up and likely your best/cheapest way to go. This is a good time to put in a slip yoke eliminator kit for the rear driveshaft and a new, stronger shaft in back in case you want to offroad this later and lift the vehicle.
 
Your 92 Wrangler will have leaf springs BTW both front and rear and look like this:

IMO- If they put it on a flatbed. They pulled it up on the bed of the flat bed and that was the only towing that went on with the Jeeps wheels on the ground. If the wheels locked then there is no telling what happened (as far as stress and potential cracks) up stream from the wheels to the transfer case. There are a lot of parts fron the tires to the T-case. My 2000 locked the front pinion bearing to the pinion shaft. Which also fragged the driveshaft Ujoint both front tires and also scared the #$% out of the wife and I. You are lucky he wasn't hurt.
