zippoc04 Posted March 20, 2023 Posted March 20, 2023 1986 Jeep Comanche X 2.8L / AX5 / Transfercase UNKNOWN / Front axle UNKNOWN / Dana 35 / LWB Build date: Sticker not present, unknown. Built in Toledo factory. Current Location: San Antonio, TX. Status: On the road, and project underway Notes: Factory fog lights on bumper, super desired black spoke steering wheel, tan exterior, black cloth interior, bench, floor shift. Current owner: Me REQUEST: Any info others can share would be very desirable. Specifically interested in build month. I don’t believe it has the early 86 firewall, but how to identify would be helpful!
The86manche Posted March 20, 2023 Posted March 20, 2023 The transfercase should be a 209 unless it has the electronic transfer case switch on the center console. I don't remember which tcase that is.. And the front axle is a dana 30 with the center axle disconnect.
Pete M Posted March 20, 2023 Posted March 20, 2023 Close, it's likely a 207 if Command Trac. the Select Trac option was (I think) the 229.
coheed Posted March 20, 2023 Posted March 20, 2023 As far as I've heard the NP228 only came behind the autos no? I can say my AX5 has a NP207 behind it.
zippoc04 Posted March 21, 2023 Author Posted March 21, 2023 You are correct, it is indeed a 207. Hadn't yet crawled under the front of it until today. Also did confirm it is a Dana 30 up front with the awful, yet still functioning, vacuum-driven CAD. Thinking of putting Dana 489s all around and sticking it on a 6" lift with 35s. Want it to be a beach runabout that can handle heavy overlanding. Really hoping to do an LS1 swap as well, add some more reliable fuel injection instead of the 2.8L. The thing purrs like a kitten, no valve noise at all, just has a slight leak from the notoriously crap rope rear main seal. Probably will retain the 2.8L for originality, but if there's any sort of market on those things, may get rid of it as well. Not really loving the transmission or t-case it's paired to. Again, all functional and no faults, just not known for being strong. Will likely opt for an AX-15 and have a few in spare for when I get too excited wheeling it hard with the LS1.

The86manche Posted March 21, 2023 Posted March 21, 2023 I stand corrected, I must have missread my tag years ago. it is a a 207. So don't listen to me, listen to the ones who know more
zippoc04 Posted March 22, 2023 Author Posted March 22, 2023 I’m already loving the banter here…my people. While we’re on transfer cases, how is the NP231 on high torque applications. Now very heavily considering the Cummins 2.8 which puts out something like 360 ft lbs. Can the internals stand up to nearly 1000 ft lbs at the output? That’s about double what it was designed to behind the 4.0s

That’s about double what it was designed to behind the 4.0s the innards can be upgraded (6 gear sun, wide chain, etc). but if in doubt, look into the 241hd

The 9 internal viscous coupling that was found on SJ's but ultimately is the same as the 228. Thats the only difference. As far as what it was found behind, its AMC gents, it was more than likely found behind both auto and manual. I will be putting in a 229 in Chunk.
