Can't get into 2wd because I have the wrong tab...anyone have measurements for it?

I started with a 249 (1998), that was skipping at low speed turns. When I opened up the 249, everything looked pristine, so I assumed the VC was the bad part. I decided to go with the 242 swap to save money.

I found a 242 (1997, supposedly) on craigslist, and when I picked it up, all the bearings, chain, etc, were more worn than my 249, but everyone says they last forever, so I just switched out some of the bearings and swapped the inputs. Also, the output shaft was a little long so...I just cut it short and it barely fits the rear drive shaft:-D...was that okay to do?

2 problems:

1. The shift tab I got (the part of the linkage directly attached to the tcase with one rectangular hole and one normal hole) is too long; it seems that the guy had given me a 249 shift tab with my 242. Does anyone know the distance between the holes so I can just drill it out? Right now the car only goes 4ft, N, 4Lo.

2. When I put the car in 4lo, it makes quite a bit of noise and jumps/skips when I turn, just like when I had the 249 in it. When I'm in 4FT, it makes less noise and doesn't skip. Is there a part in the tcase I have that's broken? I know you guys say it takes a bit of time to wear into the 4wd if it hasn't been used, but the 4ft is fine...

Any help is greatly appreciated! I wonder if I'm going to have to get another tcase:-/.

Thanks!
the 242 linkage is different from the 249 linkage. you can't reach either 2hi or 4lo with it depending upon how you adjust it for most people.

As you quoted there, That is another i been waiting to hear. Can you cut that output shaft to fit the OE internal driveshaft and get away with that?

Yeah, I'm trying to get the dimensions of the 242 so I can just drill the hole into the tab I have...

Really? My 98 5.2 with 249(I think, It's the one that just has 4ft and 4-low) does not hop or skip in 4-low on street I have drove around quite abit just for the fun of it. It's good and smooth.

Driving it in 4 lo with a 96-98 transfercase will mess it up on the road.

93-95 should be fine.


Cant tell what you have. On phone.

Sounds like someone might have put an early 249 in it at some point. A later one (96 - 98) should lock the shafts in 4lo. The early ones didn't (just limited slip).

i'm pretty sure the 249 tab is only about 1/4" longer than the 242/231. the actual link from the lever to the tab is different though as well and will bind up as it doesn't have enough throw on it to work..

if it doesn't hop or skip when turning in 4 low on dry surfaces, the front isn't getting power. so you've got something broken or removed in the front end. no other explanation for it, period.

the early ones were a very high bias limited slip, they will still hop and bind in 4low on dry surfaces.

I thought the limited slip was the same in high or low on the early 249s (center diff with the VC in the middle)? If so, I don't see why it would bind any more in low than high.

Hey guys, the length of this shift tab is what I'm looking for. I plan to just drill the hole in the one I have and call it a day. Does anyone have this measurement? I can do some on screen measurements, but I would prefer if someone actually did it with the shift linkage in person:-D.

At the bottom of the page, you can see a picture of the 2 levers. The 249 is twice as long as the 242.

I've tried to replicate what you're reporting, and I think I can explain.
First, I believe your initial installation had the correct configuration (if not parts). But because the tc shift lever is so long, you are unable to shift into the extreme ends of the gear range (2WD & 4Lo). 4Lo is prevented, as the tc shift lever is probably in contact with the tc front case at this point; whereas, 2WD cannot be entered because the tc shift lever cannot be pulled forward far enough into the proper position.

This is the part you're looking for:



I'm pretty sure this is how it attaches. After going through the FSM, and looking at how the entire shift linkage assembly goes together and functions, the shift lever rod enters the transfer case shift lever from the side closest to the tc front input. The rectangular slot on the tc shift lever should be straight up and down, with the tc shift lever itself approximately at 45 degrees sloping downward towards the front. This is 2WD. I know the pic is a little blurry, but I just crawled out on my balcony (it's past midnight) to snap it.



When you pull the shifter backwards, going from 2WD to 4Lo, the shift lever rod will swing the tc shift lever backwards as well, thus cycling through the gears.


Sorry to hear about it, but atleast your jeep will drive, and it's just a quick fix once you've got the part.

Good Luck!

What method did you use to install the trans output seal? and did you have any issues installing the input and output seals on the tc?
