Discussion Starter • #1 • Mar 27, 2009. These shafts have to be the same length.. The NP249 is a strong Transfer Case (TC), but its weak point is the Viscous Coupling (VC). the SYE let me increase the length of my driveshaft by over 4"..Pulled the 249 outinstalled the SYE kit in the 231installed the 231 in the ZJ. If not I've shortened and balanced my own shafts. One of the main drawbacks of the '93-95 ZJ version of this case is the lack of a low-range lock. The short one came with the 231 and the longer one is the 249. Remove the aluminum cover on the front of the case, remove the input shaft snap ring, remove the front output yoke, remove the 10 15mm bolts and the 1 12 point 10mm bolt, and finally pry the case apart. Please      I have my existing NP249 setting on my bench next to the NP242 I just bought. With patience you can have a balanced shaft on the cheap. We pulled the 249 t-case out and by chance it had the same length input shaft as out donor NP-231 from a '03 TJ. In other words, if you get into a sticky situation and need both driveshafts turning to get you through, this transfer-case will only act as a limited-slip and not mechanically lock the two driveshaft to turn in unison. The 249 was built in January of 1997 and the 242 in July of 1997. Measured for the new drive shaft and called it in to the driveline shop. Driveshaft shops are hard to find here. Filled the transfer case with Dexron III, ordered the new shift pattern plate from the dealer and everything worked great. Had it back the same day and installed it. The ZJ I have is a 1994 4.0 and uses the NP-249 which is a full-time transfer-case that utilizes a viscous coupling to act as a limited-slip betweed the front and rear driveshaft. Filled the transfer case with Dexron III, ordered the new shift pattern plate from the dealer and everything worked great. Welcome Guest.

The 242/231 disassembles much like the 249.

You can not use the longer lever from the 249 on the 231 it will fit but will not allow the 231 to shift right.I do know that they make a couple of different gear cut and they would not fit or work together and they also make 3 different input shaft lengths. The 242 looks much like the 249 inside. STEP 1 - Research what type of transfer case you want: The Jeep Grand Cherokee came stock with the NP-249 transfer case.While a decent case, many people have negative opinions about it due to it only having three options (4-high, neutral, and 4-low) as well as the viscous coupler going out (the clicking and popping you hear on tight turns). I got my case from a 90 YJ and needed to swap input shafts. Before we get to ahead of ourselves on the swap, let’s discuss why you would want to swap. NP249 to NP231 T-Case Swap - Operation Cheap Jeep - YouTube The other distinction I noticed, is that the bolt pattern, where the two are mated to the transmission is slightly different.Are you on the island? I don't know if these are different because the 5.2l and 4.0l are different.I decided to install a SYE kit to help alleviate any driveline vibes and to eliminate the pesky slip yoke that is always letting dirt in and fluid out. Usually you can swap the input shaft from the 249 into a 231, but there was a change in the gear cut right around 94 or 95. The one from my 249 (1995) was the wrong gear pitch, which would've seriously screwed up the t-case. Measured for the new drive shaft and called it in to the driveline shop. I have noticed a couple of differences though, in that the 242 is rougly 1 inch longer, from front input to rear output, which suggests I might need to have my drive shaft clipped and balanced. There seems to be an older 21 count spline and the newer 23. Had it back the same day and installed it. Set the new pinion angle in the rear and took it for a test drive…no vibes at all. The 249 and 231 I had both had the 23 spline count.The shift levers for these cases are different so you will have to use the lever that came with the tcase. NP249, NV249 Transfer Case swap to NP242 or NP231. Personally I'd just swap in the 242 and see if the shaft will fit.
