I know one person on here is supposedly doing the switch. There is a company that makes a 4.0 application specific kit, but it is and isnt legal for street use. Its only legal if proper safety equipment etc is used due to you caring a pressurized tank in ur vehicle that is highly explosive/flammable lol. But the kit does away with all computer control so ur back to carb country

My 96 won't start. I just got it together after having the head rebuilt and it did run before this. I have spark and fuel, and have tried a small shot of starting fluid with no success, not even a pop. The distributor was not touched, so its not 180 out.
Am I overlooking something simple?

Anybody?

If you have the NP242 transfer case there is a differential which will let you operate on high traction surfaces safely, but only when "full-time 4WD" is selected. The more common NP231 will do the above and your drivetrain will rip itself apart.

Ehhh no... Unless you only literally go in a straight line, using 4H on a dry surface without any opportunity for tension to be released like in mud, ice, or snow, you're going to cause damage just like the OP found from the front U-joints to the transfer case. Theres a giant sticker on the drivers side sun visor about this.
Those with a 231 "Command-Trac" T-case can not use 4H Part-Time on dry pavement. However, 242 "Select-Trac" T-case owners can use 4H Full-Time on any surface. I believe the 242, when in 4H Full-Time, allows for slippage within the T-case to prevent power train damage.

A np231 all tires turn at same time and travel in same direction so when you trying to turn in 4wd in a np231 what happens is your front tires are turning but your rear tires are still trying to go in a straight line causing it to bind up and this can potentially damage drive line parts.
Even in a straight line your shouldn't use 4hi on the command trac cause if you have good new tires you're still causing stress on the driveline cause of te added stress from the tries gripping and not slipping.

What it is with the np242 is that it allows for the front and rear wheels to turn at different speeds. So it won't bind when turning.

I see. You know, this thread got me researching the difference between the 231 and 242. Pretty interesting stuff about the two. Seems like it's split down the middle as to which is better. 242 seems better for mild winters where you drive on snowy and dry roads. 231 seems better for constant slippery condition driving where you're not likely to encounter dry road for a while. Good stuff, good stuff.
