ive looked for anything on the nv249 but havent found anything maby i just havent looked hard enough. i have acsess to a NV249 (needs rebuild) has any one ever done this swap? can it be done? what would i need? it came out of a 92 or 93 jeep i believe. ive got a 84 waggon with a built tf998
I like the idea.
The 249 was available in two versions, both with viscus couplers like the Eagle. The early (1993–1996) version had no differential lock. The later version (1996 and beyond) had a rear torque bias, but included a provision to lock the center differential.
The only two things you need to look at are the rear output, I don't know if it's a slip yoke or a fixed like ours; and the speedometer output. Both can be overcome, but if you need to change the rear yoke you'll need a slip yoke eliminator or have a Jeep drive shaft re-sized to fit.
On later NV/NP cases digit one is 1 for four wheel drive only, 2 for two wheel drive available. Digit two is the case series, and digit three indicates differential type, 1 for no differential, 2 for open, 3 for electric locked, 4 and 5 both indicate an asymmetrical torque split planetary gear and gear drive, 6 means an electronic clutch pack, 7 means a hydraulic clutch pack, and 9 means a viscous coupler.
i like the idea that its a full time unit (not that ill ever need it) and its a low range unit wich is what i was really after. i do plan on taking it to the strip here n there and that will really help it get out of the hole like a bat out of >:D as well i plan on doin some wheelin and it would be nice to have the 4low if i get into some rocks or somthin. o almost forgot 4wd donuts are FUN! lol thanks for the info man. i wonder if it does have the slip yoke if i could just swap out the output shaft. it needs a rebuilt any way ya know
Yeah, and the non-locking low would be great for towing since you can start out on a dry paved surface in low.
really? SWEET! we do a lot of towing here (espicially with all the horses) we feed giant round bails roughly 1500 lbs. now i need to find a hitch. lol
