My 2000 SE 4X4 Xterra had an intelligent ABS that could detect the surface material so that it could be used in 4WD. In fact, it was one of the only SUVs that had 4WD ABS as most other's ABS deactivated in 4WD.

I would expect that ABS technology would go forward instead of backward, maintaining 4WD ABS in our Titans.

Have a good one.

***If you have a 4X4 model, you have the ABLS front and rear. ALL 4X4 models have it standard, regargdless of options. If you have a 4X2 model, the ABLS comes only in the Off-Road pkg on SE models.
Yes, you either have VDC or the E-lock, not both. ABS works in 4WD as well as 2WD.
Again, ALL Titans have open differentials.

Batman,

"You get one wheel in the air or pretty much unweighted dont gas the crap out of it the system wont work, the power of the truck will jsut overide the amount of force the brake can apply causing the unwieghted wheel to still spin uslessly or dig a deeper hole."

I'm not sure just how you tested your truck but, I've not found that to be the case at all. Nor will the system not work during a turn. The system doesn't allow too much wheelspin before kicking in. I've had it work in a corner while on wet pavement myself. With one wheel on solid ice (same as in the air) power is distributed to the wheel on solid ground (Did this one and NOT on purpose!). I'd also bet that no two people will get the same exact results in each situation because there are probably too many variables involved.
As for an open differential, any open diff will spin both rear wheels for a short stint until one wheel overpowers the other (one will always lose traction over the other eventually), then you'll get just one black line. The double black line won't last much more than a few feet before this happens. However this can also vary depending on the surface.

You're the first person I've heard that thought the LSD rear in the Xterra/Frontier (same) did anything worth a damn. I've spun many a right rear with no intervention from Nissans "LSD" rear.

SHORTY,

I'm not surprised by his answer. Many saleman have no idea about the VDC/E-lock delima, or why you can't have both. I asked in the beginning because the brochure (the 04 brochure) showed BOTH the VDC and E-lock buttons on the dash in one of the pics. TOGETHER! As it turns out, it was a misprint, and you can have one or the other but not both on the same truck. The only reason I can see is that the electronics don't work together.

I did this with my Xterra and it's LSD saved my @ss. It finally found a spot without ice and pulled out of it.

I've had nothing but good luck with it. After I drove a Mitsubishi Montero Sport in 4WD without LSD, I really started to appreciate the Xterra's LSD.

Have a good one.

onebadse- When you come around a corner and nail the gas once in the turn, not before the turn, your power gets distibuted to the outside wheel, or both? I have not yet been able to make this happen, the inside wheel just rips. I enjoy putting my truck sideways but can only do so in the dirt or certain pavement types in the rain. Also do you know anything about the e-brake not locking up the rear wheels? Where is the fun in that!

It depends on how fast you're going and how sharp a turn obviously. But in normal cases, one wheel will slip slightly, the "SPIN" light on the dash blinks, and power is directed to the other wheel. I've noticed this a few times because we had an early snow a week or so ago, and they sanded the roads. Well at some intersections, there is excess sand so when I make a turn under power, the one whel slips a bit, the light blinks, and power is redirected.

The E-brake is mechanical meaning it's not part of the hydrolic system. Therefore it's not part of the antilock system either. If you push the pedal hard enough, it should lock the rear wheels.

Its some kind of saftey feature or something the rear wheels not locking up. Last night I smacked it into nuetral and slammed the brake on some leaves. The truck quickly and safely came to a stop, no skidding. Cars are becoming less and less fun.

With a clutch pack or Torsen Limited slip differential power should go to both wheels in this instance. With an open differential, detroit locker or a brake activiated limted slip system the inside tire should go up in smoke. I would think the ABLS would defeat its purpose if it intervened at speeds above 30 mph, the VDC system however would step in and make the inside tire stop roasting if you stayed in the gas in the case of the titan. I'm no expert but I assume the benefit of the ABLS system comes in more so when starting from a stop, or off roading when you have a wheel off the ground. With a wheel off the ground I don't think unless you had a chattery tight clutch pack diff. that you would be able to get the grounded tire to recieve torque and you might as well have an open diff. Of course with abls the grounded tire will get the power, i've tested and confirmed this. Another disadvantage IMHO of a clutch pack lsd in a pickup truck or any rear drive vehicle comes on slippery road when entering a corning, you let off the gas entering the apex of the turn, because there is friction between both wheels the inside tire will make an attempt to keep up with the outside tire, there is not enough traction for the tire to over come the friction of the LS and with the limited traction it spins to fast making the rear end step out and you have done a 180 before you know it. The tighter you set up the differential via friction modifier or lack there of will compound the problem. The biggest weekness of the ABLS in my mind would be its staight line pavement acceleration, since it has to cut back engine power to accomplish its mission, it will slow acceleration down compared to a typcial LSD.

import2nr, i was thinking of doing that exact same thing, but was hoping someone might know to save me the trouble. i will do that over the Thanksgiving weekend and let everyone know.

yes, you have an open differential, until you engage your sweet e-locker, ment for off roading or on boat launches (slow speeds)

a real meachanical LSD would a nice, better than a E-ALSD Brake that the non-E-Locker Titans have, like mine. Corvettes, S2000s and some trucks/SUVs come with real LSD.

I waiting and waiting for: mechanical Detroit Locker, ARB, or E-locker to install in my Titan's real axle differential.

In addition, I plan to add an ARB or an E-locker on the front axle differential.

I am NOT going to lift my truck, as i rarely ford across rivers or deep creeks, and the stock 11.5x33 tires would perform fine with such traction aids lockers on both axle differentials. Lifted truck, while looking very cool, tends to flip over more on highways and off-roads.

oh looks like i am rambling

My E-ALSD Brake kind of works on snow & ice, but the feeling's wierd... aint goning to be right about it untila i get real locker on BOTH axles (and a big winch).

Right, the ABLS will not lock the wheels together, which is a GOOD thing. The arse end would be all over the place if it locked. That's what the E-LOCK is for! In all actuality though, I've owned truck with 4WD and only open diffs front and rear. It's not easy to get it stuck or have it behave scary in bad weather unless you're driving like a loon...lol.

It's my understanding from speaking to a couple friends who are Nissan techs, that the VDC does not do a thing in a straight line. It must detect a difference in wheel speed (more wheel speed difference than a normal turn)while the yaw sensor (G-sensor if you will) detects a certain lateral G, meaning it knows the truck is about to go all sideways on you by the lateral Gs and the fact that there's a wheel slipping. The ABLS would take care of straight line wheelspin otherwise.

Lets just hope all this stuff works as claimed. Then we don't give a rats butt HOW it does it....so long as it does it!

Just want to ask about the VDC. Is it an option on the 4x4? I have a 4x4 LE with no elock. I know i have abls but i've searched through out the manual and couldn't find an answer. if anything it reads that it is an option.

[Batman229]

How does Chevys auto locker work? They have them on there pickups. Also dodges limited slip works very well. I drove a hemi around for a week and left 2 strips every where I went and could put it sideways with ease on dry pavement. The E-brake also locked up on the dodge. Also does the rear locker stay engaged after you take the truck out of 4lo without turning off the button? This may be how I could get 2 patches when I power brake. Anyway see any harm being done to my truck this way?

If you have the BIG TOW package w/o the OR package, you have the VDC (Will be on your window sticker). However, if you also have the OR package, you'd have thr E-LOCK in place of the VDC (depending on build date).
In any case, if you don't have any of those packages, you don't have either VDC or E-LOCK.

Yep, it's called a "G-sensor". It reads the terrain and adjusts the ABS system to allow more or less lock-up before intervention sets in. The Titan has the same exact system. But the Titan, unlike the Xterra & Frontier, have a true 4 channel ABS system as opposed to the 3 channel (2 front one rear) setup in its' younger siblings. The new Frontier, Xterra and Pathfinder have the newer systems found on the Titan from what I've read.

Chevy has used a variety of limited slips over the years most recently on pick-ups they have used whats called the "eaton locker" it funtions like an open differental allowing the rear wheels to turn at different speeds while going around courner, how ever if one wheel spins at to high rate a speed compaired to the other flyweights engage the clutch packs forcing both axles(wheels) to turn at the same speed. Older chevies (60's) used whats called an "eaton posi" which uses a preloaded clutch pack to limited the different in spead of the one axle shaft from the other, the more load the is applied from the engine the harder the clutch packs are applied from force from the side gears. This type of limited slips is still avalable on the aftermarket and is a very ruggid piece, it is also very similar in function and behavour to the auburn limitedslip with exception of using a clone instead of clutch packs.
-The detroit lockers fuction completely differently again they use big clock gears that rachet while going around a corner (assuming to much trottle isn't applied) they operate on the principal that the outside is allowed to turn faster than the carrier around a corner but the inside wheel can never turn slower. Detroit lockers are extremely ruggid and offer very good traction how ever their paved road behavour leaves a bit to be desired.
-Air lockers and the e-locker fuction as an open differenental until they are activiated which then acts as a spool (holding both axle shafts together). In theory you should get the best of both worlds.

Hi All,
This Is My First Post. I Have Been Reading For About Three Weeks.
Thats When I Bought My Titan. So Far I Love The Truck!!!! Only Problem So Far Was Gas Gauge, And I Thought E-lock Problem. E- LOCK IS NOT WHAT I THOUGHT.my Dealer Told Me That The E-lock Only Works In 4-low Up To 19 Mph. I Have Since Tested This And Thats How My Truck Works. It Took them 2 Days To Find This Out. I THOUGHT E-LOCK WORKED IN 2 WHEEL DRIVE ALSO. Does Every One Else Find This To Be True. I Was Dissapointed!!!! Love The Site . Will Respond To Other Threads Soon.
