249=> 242 TC swap in a Daily Driver

I recently swapped my Transfer Case from a 249 with a shot VC to a 242. I use the vehicle on a daily basis, and have not ran into any problems ().
Many people have done this to their off-road ONLY rig, but I was wondering how many others have done this to their DD without issue?
On a separate note, could someone explain to me how the 242's Full-time 4WD works differently than the Viscous Coupling in the 249?


'93 5.2L V8, Laredo, 242 TC swapped from a 249, 3" Coils up front and Front coils in the Rear, JKS Adjustable Track bar, K&N Cold Air Intake with Amsoil filter, Rear cargo area shelving, and KOR's Steering Gear Brace, IRO's Over-The-Knuckle Steering, Top Light Rail, Top Tire Carrier... for now...
OR If you prefer acronyms: 93 5.2 V8, 249>242, 3" FC, ~2" RC, JKS Adj. TB w/ KOR TB Bracket, K&N CIA w/ Amsoil filter, Shelves, KOR SB, IRO OTK HD steering

I am interested in doing the same project and my Jeep is not primarily a trail rig.

My understanding is that during part-time 4WD the center differential is locked much like having a locked rear end, the power is split 50/50 front to rear.

During full time the center differential is open and just like an open rear end the power will go to one end or the other, usually the end with less resistance to rotation. Full time in a 242 has less traction than the full time 249 which uses a viscous coupling to account for different speeds front to rear.

I think the idea is that you still have better traction in full time than in 2WD but you can run around all day without concern for damaging the transfer case.

Exactly .... not much of a change in MPG either.

why would there be in issue with doing this to a jeep that is a dd?

I dont understand the question.

231s, 242s and 249s came stock in various ZJs so why would running one have problems over another onroad only?

ZJs came stock with 231, 242, & 249 transfer cases depending on which year/model you have. There are no problems with running any of them as a DD

with that being said.. i have swapped my 249 out for a 242 in my DD ZJ and its one of the best mods ive done

Yea, what he said. No reason in the world any of these tcases can't be used for a DD. I opted for the 231 when my 249 bit the dust, and have driven it 70 miles a day for the past year without issues.

Cool. It makes me feel a lot better that other people have done this too.

Sorry, I guess I wasn't specific enough. Even though some ZJ's come stock with them, I was worried because I had never done any repair that massive to a vehichle. Just wondering how many other people had done the same with similar results.
Sorry for bugging all you super-jeep guys with my curiosity.
