ORANGE! Saw one at my local "dealer" in New York. Well tricked out WITH cdl linkage and seats that look like a cross between fabric and tent material. Only had the in dash CD stereo and was short other extras my 99 D2 has...but the paint job looked real nice and this car had Michelin XPCs on 16" rims...anyone got $39K loose?....:-)

for $39k ill sell you my '00 and paint it orange for ya. Oh and itll kick the crap out of a '04. Does this mean that the dealerships can no longer bitch about adding CDL to D2's? thatll be nice. or does the orange paint somehow make it work ok and not kill the abs pump?

I never really thought about it, but if you installed CDL linkage on a D2, wouln't the TC constantly activate whenever there is slippage, therefore negating the CDL and wearing out your breaks prematurely, or do you bypass TC with a CDL installed? Presumably, if you have one wheel spinning due to the CDL, and without the CDL it would otherwise not have power going to it, wouldn't TC apply brakes to that wheel? Probably a newbie question, but i'm curious.

ETC definitely does not activate as frequently with CDL engaged, given the same/similar conditions. My guess is that ETC is predjudiced towards same-axle wheelspin, though it reacts to alt-axle wheelspin as well.

If you think about how a locker works and then consider the front and rear to be single units (even though there's an open diff at each end), it would follow that ETC would have less work to do, if I'm right about the above.

Anyway, I'm over-analyzing it....real world conditions are hard to argue with.

Keep in mind, with all open diffs and no ETC, you can jack one wheel off the ground, put it in gear, and hit the gas.

Why would it make any difference? The ETC measures (and responds to) slippage at the wheels, that is how it is possible to have a 4 channel system. Your diff lock is in the center only, it is stopping differentiation of the front and rear prop shafts only, it has nothing (directly) to do with what individual wheels are doing. Your wheel will slip on the same ice in a '94 as it would on a '00 or '04 - it's the ability to stop spin that makes ETC so effective - but the ability to work inspite of electronic failures that makes center diff lock so desireable.

If that is the case, then it follows that the ETC system in an '04 with diff lock, is better than the same truck with only diff lock, or only ETC; and not only because the ETC in the '04 is 2 generations ahead of the ETC in a 00'.

Again, if you put a diff lock in the center of an otherwise open truck with ETC, all you are doing is stopping the diffentiation between front and rear axles, not the slippage of the wheels individually - which is exaclty what an ETC system does. If you go off-road in mud, with the diff locked you are more likely (25%) to cause one or more wheels to spin - the truck with ETC or lockers on individual axles is the only way to attempt to overcome this.

ETC = Electronic Traction Control
CDL = Center Differential Lock

When CDL is enabled the CDL position sensor reports back to the SLABS ECU. SLABS is aware. The caveat is that you must have CDL disabled prior to rebooting the ECUs otherwise ABS and ETC functions will be disabled entirely.

All 03 Australian cars have the lock fitted and I haven't heard any complaints. The early D2 cars without the diff-lock tend to loose momentum in soft sand and mud from what I've seen.

Thats all bollocks. I have taken my 02DII manual v8 through the most crap beach/bull dust conditions. I have no CDL only ETC. I have towed a dual axle 2.5 tonn van through some awefull beach sand. I have attempted to bog the bloody thing in thick heavy beach sand and so far the ETC has worked well - the secret (not so secret to some) is use the throttle like there is no tomorrow. Where it can be a little less solid is up steep slippery slopes and then usually it just ends up spinning more than a CDL equiped 02; overall CDL helps, but there is fuck all in it.

Scottie I think the admins might come down on your language pretty hard, so put on the kevlar
TC like ABS works best when you hammer it, but the mechanical sympathy side of me hates the idea of doing that....hate to suddenly gain traction and hear a loud crack as a driveshaft pops.....
