Towing a TJ on a dolly

[mrblaine]

I thought that the TJ and YJ 231's were basically the same. I have interchanged them before with only seeing am minor difference with the front output shaft drop being slightly different. Or am i missing something Blaine? Tim

Apparently the TJ 231 has a true neutral. I would back that up logically by the fact that the YJ runs an axle disconnect instead of a neutral disconnect like the TJ does. However, I don't actually know for certain. I do know they are not the same externally.

According to a plausible-sounding theory in a thread on one of those other forums, it has to do with the chain sprocket bearings. An older 231 apparently has needle bearings for the sprocket, minimizing long-term wear due to the fr/rr shafts spinning at vastly different speeds, i.e rear shaft spinning, front shaft not spinning. Probably similar in any t-case intended for use with locking hubs or front axle disconnect. Newer 231s, 241s, etc, apparently don't have the needle bearings, only a "surface" bearing, as the two shafts spin at approximately the same speed most of the time, therefore little long-term wear.

I've never been inside a t-case, so can't vouch for or against this theory

I do know that my 94 did not have the disconnect. I think they stopped it in 93 maybe?

I had a buddy with an 95 and he had the disconnect. I was under the impression that they continued it until the YJ stopped?
