What I was trying to find out is what diff, or both are used in the Quadradrive vs Selectrac. And does the Vari-lok only come in the 44a?

As I understand it, all 4.7L motors had a D44a behind them. All Quadradrive had varilok front and rear. Some Selectrac had varilok rear, it was an option (I have one).
I don't know if all 4.0L had D35 behind them but I think most did, unless they had a factory tow package. I think the D35 did not have a varilok option.

More confusing. The chart here http://www.wjjeeps.com/tcases.htm Shows models with only rear LS, Trac Lok 99-01, and Vari Lok 02-04 in 2wd. Quadradrive has front and rear Vari Lok. I'm looking at used trucks right now and several have a 4.0l and Quadradrive. And that's my question, does the 4.0l quadradrive have the 35 or 44a.

I guess from what I've read you could special order that. What year is your WJ?

I do not know exactly, but i believe that the Quadradrive system WAS available behind the 4.0L, but it appears to be very rare here where I'm at. I have seen one jeep setup this way in the wrecking yard. I did not investigate super close, but it appeared to have the 44A rear diff. I believe that the only thing you got with the quadradrive system was the dana 30 front, and the dana 44a rear. I have never heard of, nor seen a dana 35 rear with vari-lok. And quadradrive always has vari-lok axles.....

I have a 2002 Laredo 4.7L SelecTrac Class IV tow package Up Country with varilok rear diff, Patriot blue no sunroof. Told the dealer that is what I wanted back in 02 and he found one for me.

Easiest way to identify D35 vs D44a is look at the shape of the diff cover. Not too hard to get a visual on it if you are on site with the rig.

I'm in CA and there are a few popping up with the Quadradrive that are 4.0L.

I just realized that in the pic I posted, the D44 is the standard model and not the D44a. They are similar though. The D35 cover is accurate.

More Axle Talk

So this thread was to try narrow down what WJ to buy. Lot's of talk about Quadratrac having the Vari-Lok diffs and how that is a good option to put a 242 TC in. But they are not serviceable, so how durable are they? Replacement carrier availability down the road? Also reading about Trac-Loc not really being any good. What options are available for other LS carriers in the 44a vs the 35 axle.

Not really interested in a lunchbox type locker but would consider a selectable for the rear at some point if I end up with open diffs. Like I said before, no serious wheeling but I will be in somewhat remote places and alone at times. Also likely won't go bigger than 33's.

ARB or lunchbox are the only options. Why are you opposed to a lunchbox style out of curiosity?

Seems opinions on them are 50/50 and I'm somewhat turned off by some of the sounds that come out of them. Tell me something good about your experience with them, maybe something to consider with more info. Definitely an easier, lower cost option. I'm limited on funds but I understand buy once, cry once.
