What's the best and cheapest way to add "two wheel drive" to the Dana 35? My Cherokee is mainly street driven with 4WD used in winter snows and occasional forays off road. I don't want anything "clunky" like a Detroit Locker....

Were there many factory "limited slip" type setups built so as to be fairly common in the wrecking yards?

BTW, I once "posi'ed" a 9" Ford by adding a few shims. Can that be done easily to the Dana?

PS No spools or welded spiders either! Razz

Unless you weld them, the spiders have to come out and either a locker or LSD go in. The cheapest would be a lunchbox style locker, but those click and clunk when you corner. After that, you are looking at doing either a full locker (selectable or not) or an LSD...both of which will require a full gear setup.

There were quite a few LSD's put in XJ's (in both the D30 and 8.25), so junkyard diving would be a good way to find an axle that has one.

How would a guy know if his 96XJ already had an LSD front Dana 30?

Certainly the Dana35C rear seems to run open . . .

Docchaynes- the Cherokee certainly didn't come from the factory with a LSD in the front. To see if you've got a limited slip you would want to put the front end on jackstands and rotate one of the wheels by hand and see if the other wheel rotates as well. Otherwise you would have to either crack the diff case open and see whats in it or try to find a situation where only one of your front wheels would have traction (and both of your back wheels don't) and see if your Jeep can pull itself through it.

Bucks- what year is your Cherokee? If you have a '96 or newer and you have the factory LSD installed your transfer case (I'm sure of the 242 and 249 but you'll need to check for the 231) will have a lo-lock feature that will effectively lock your diff and the coupling in the transfer case when you put it in low range.

i have a 98 classic with the 8.25 and lsd. does that mean my nv242 locks in low-range? Very Happy that might explain why my jeep can out climb my buddies 96 with a nv231................but the fact that he's open might factor in there somewhere Smile

T-cases were designated either NP or NV. They are essentially the same t-case, just a different "brand name". NP was used for the purposes of this list:

NP ="New Process" NV = "New Venture"

NP207 - "Command-Trac" part-time only - 2.61:1 ratio low range - used 84-87

NP231 - "Command-Trac" part-time only - 2.72:1 ratio low range - shift pattern 2H - 4H - N - 4L - used 87-01

NP228/NP229 - "Selec-Trac" - 4Hi(full-time) - N - 4Lo (part-time) - used 84-87

NP242 - "Selec-Trac" part-time OR full-time - 2.72:1 ratio low range - shift pattern 2wd - 4part-time - 4full-time - N - 4LO - used 87-01
