2 Wheel Low

[XJWheelie]

Isn't there some way that I can get 2 wheel low? I'm sure that it means buying and adding something, but I'm not sure where to begin.

I have heard some Jeeps (I think waggies) had in cab vaccum switches for the front axle. You could work one of those in if you had a disco axle. I have thought about it for mine.

Also if you have a vacuum disconnect axle up front you can get the 4x4 posi-lock unit. It replaces the vacuum actuator with a cable drivin one. this would allow you to engage the regular lever in 4low and it will not engage your front axle that way your t-case is giving you the low gearing to the rear axle only.

yes there is a way do do it, but; without knowing what year you have and transfer case, cant give you an answer

if you have a locker up front the posilock or the switch you will not be in 2 low but it will help turn and maybe break some stuff.

I had one of these in my 88 t-case. I had it pop into "true neutral" while heading down a ledge once. The kit I had was from Advance Adapters, it basically adds another tooth to the shifting fork. The 4LO setting is just above the "true neutral", meaning if your 5spd is in gear, when it pops out, your drive shafts are in neutral. You'll only have brakes to stop you. I think this is because the kit crams five teeth in an area meant for four. So the points of the teeth are closer together.

The kit works great if you want to steer in LO with a hard locker up front. Just understand that these kits have been known to pop in to neutral.

It's much easier to get manual front disco, just unscrew the transfer case vacuum swith and plug the hole, put it in your dash, attach half of one of those main power switches (or what it's called, a beefy switch to put on your + cable to cut all power to the car), hook them up so that the switch pushes the vac switch in when you turn it, done.

Thanks

Thanks, the TeraFlex kit sounds like what I'm looking for. Only thing is if I add a slip yoke elminator kit and the 4 to 1 kit then I've got one EXPENSIVE NV 231 t-case!

JJ,

I think you mean tera not AA.

XJWheelie,

You also have what is really close to costing as much as a Atlas II.

If you have a vacum disconnect, you can also do it with a couple of 3way 12 volt solenoids. Pretty much works the same way as the rightcoast crawler link above, but has a simple push-on / push-off button on the dash. If you understand the above article, you can quickly see how the 3 way solenoid would work. Been running the setup for several years without any problems. Don't think it would be much benefit with a full time locker, but with an open dif or in my case, and ARB, it's great. Did a write up in the yahoo colorado xj goup bb. Don't know if the link works, but it's in the files section.

JJ-
I'm confused now... (nothing new!) :wierd:
On mine, the 2LOW position is all the way back, past the 4LOW spot.
I have had mine pop out of 4LOW if I hit a hard bump, but I thought it was just a linkage adjustment. Shifting between 2LOW and 4LOW is nice for the tight spots, and an easy shift on mine.

WOW, I hadn't thought about that! Where do you buy an Atlas and how much do they cost? And what advantage do they have over a 231 with a slip yoke eliminator, 4-1 gearing, and the 2-low stuff installed?

I agree with Mark. If you're planning to install a 4:1, 2-LOW kit, and a GOOD SYE, spend the extra few hundred and get an Atlas. Your t-case worries would be over! :thumbup:

I actually got mine from AA when they sent me my SYE. They no longer sell them though, one of the techs there confirmed the popping out issue. and that's why they no longer sell them.

Mark was the one told me about the popping out of 4LO at Naxja Moab one year. A few weeks later on a trail in Colorado it popped out.

 

[BillR]

Interesting...
I wonder if this could be corrected by increasing the spring pressure on the detent ball. Maybe a new spring...

Sorry I wasn't clearer. While heading down a leadge I had the XJ in 1st gear 4wdLO. As my front end came off the ledge it jarred the XJ and popped the t-case from 4LO to N. I wasn't using the 2LO setting at the time. Since the kit replaces the stock fork, the teeth are closer together on the new fork. I think that is what causes the "popping out" of 4LO.

Mine didn't. I put in a 4to1 at the same time. This install requires that you remove the spring and pin, and remount it to the new front case. I can't remember is Tera gives you a new one or I lost my stock one. Anyway I had to head down to the dealership to get new ones.

My point really was it was made by tera and if anything just sold thru AA.

BTW, it is a design flaw that makes it pop out not an adjustment thing. The only ones which worked well were the original JBC ones.
