He'* either taken the front drive shaft out, or he'* change the transfer case from a NP249 to a 242. Mine will chirp if I lay it down from dirt to pave, but...thats about all.

5.9'* are beast'*

the truck in the video is a 98 5.9 limited, not an srt8. it was most likely a 4x2 though. and an srt 8 would SMOKE a 5.9

If you want a reasonable sized motor with overrated power output.. this is your vehicle.

The slogan "That thing got a hemi" came around because no one can tell if you got a hemi or a 4 cylinder.

No. the 5.9L most of them came with Full time 4X4. Some you could have ordered with the better Selecting Transfer Case, the NV-242. witch you can select 2x4.

But most likely the person switched it out for the better transfer case like many people do.

The NV-242, which has 2WD, 4WD Part time, 4WD Full Time, Neutral, and 4WD Low Range was a rarity in most ZJ'* and WJ'*. You could mostly find them in the Laredo base models with the I6 engine, but a few of the V8'* have them, too. Part time and full time are the same gearing. Full time mode passes the front output thru an open differential in the t-case, to allow the front and rear driveshafts to turn at a different rate (just like an open diff in an axle). Part time locks that center diff, to provide a non-slipping output.

Most of the V8 models have either the NV249 or NV247, which are the fulltime 4WD cases. The NV249 in the (1993-199 ZJ'* has a viscous coupling which does go bad after a while and will cease to allow slippage between the front and rear driveshafts. The NV247 uses a georotor pump to progressively engage the front driveshaft as needed. I think the 247 was just in the WJ'* (1999-2004).

The NV147, which may be found in rarity in some 2004 laredos, should have never been made.

Is the 242 a direct bolt on?

My 88 Inline 6 auto 4.0 L has a 242 with 3.55 rearend gearing.......maybe I could swap it into a newer 98.

It can do what that 5.9 can do........only the roads have to be wet.

I don't like driving it in the rain without it being in 4W Full time. It'* too darn snakey.

I'm assuming you are saying you want to put the 242 into the 98, meaning the 98 has a 249 in it. If so, the case itself bolts up the same but there are different input shaft lengths used throughout the years. Only way to know is take them out and measure. I have not done the swap but I'm told it isn't too much trouble to swap the shafts. 'Course you might get lucky and have the same shaft lengths.

and if the 98 is a ZJ with the VIC, you just take it out and there should be 2 sets of plugs behind it, one in use and one not. Swap them and the VIC should show the proper 'case selection.
