    if it's a stock 86 you've probably got a dana 300. excellent tcase. The Dana 300 was used only in CJs from 1980 until 1986. The first year the Dana 300 was available there was a slight difference from transfercases used in '81-'86 CJs. The 1980 Dana 300 features a shorter tail housing which allows a slightly longer rear driveshaft.

      What Fubar said, dana 300 TC. Also you have a T-5 trans..its a smooth shifting five speed but was never intended to last with hard off roading or higher HP motors.

      To answer your first question, the Quadra-Trac used an AMC version of the GM TH-400 automatic transmission, it is a full time four wheel drive system that is chain driven and has an aluminum case. They are not the strongest by any means. Be happy you have the Dana 300.

          i would lock my front end but i street drive mine a lot. i also keep the front hubs engages so i can just go off road at any time. locked front end and engaged front hubs make for a difficult ride. there are lockers that "self engage", but for the front i'm waiting until i can muster up the cahones to splurge on a selectable locker. i just hate to drop $800 on something i don't really need.

            Yes, its a Dana 30 in the front. Your one of the few lucky ones to get the Dana 44 in the rear, most came with the two piece axle AMC 20. If you swaped out the T-5 trans for say a T-176 you would have a great combo that would handle alot of off road abuse. Of course I know a few people that have run the T-5s for years without any problems...but they are aware of the "weak link" and don't abuse it, plus low HP motors (258cid).

            As for a locker, IMO the ARB Air Locker is king...but you need to buy the ARB compressor or have some sort of On Board Air set up. Next would be the Ox Locker, this is cable operated and has some good reviews. if you don't want to spend $600-$800, a "lunch box locker" like the Lock Right would be a good choice.
