you guys are talking like a rover can't go anywhere off-road when the CDL is un-locked. Remember a DII has traction control that automatically applies brake to the wheel that is slipping so power is sent to the wheel that has traction.

BTW, does anybody know if traction control works in 4hi? mine only seems to work in 4lo.

Land Rover calls the traction control 4ETC. By no means does it replace having the front and rear locked, but it does (most of the time) keep you from having only one wheel with drive. It applies brakes at the wheel that is spinning, thus increasing resistance, and sending power to the other wheels. The intent is that it negates the need for front and rear lockers in most situations.

That's the next question....does traction control or ABS come into play when our Discos need off-road traction?

edit: ah, I just saw the posts above (2nd page!)....so, the ETC applies a brake to the spinning tire. This in essence sends torque to the tire thats not spinning. Interesting. Does that smoke the brake pads? Is this common in other SUVs/trucks? Sounds like this feature is an intermediate between an open diff and an LSD?

you'll see a big improvement off-road but it won't be fun to drive on-road welded.

Just today i was driving in to work and went over pot hole as i was braking and traction control came on. I have experienced it a lot when in 4hi and going in a hole or coming off a curb to fast where the wheel gets to spin faster than the opposite wheel on the same axle.

if you dont have the rave manual handy the brakes section for the DII is loaded on my website which explains how it works together =)

my TC light comes on in 4hi and seems to help some but no where near as much as it helps in 4lo...maybe it's just the increased torque of 4lo that makes it so much more effective.

yes it works in high range. Atleast mine does (maybe a LR gremlin?).

That means if your rear wheels have no traction and your center diff is unlocked all the power goes to the rear wheels and in an off road situation you sling mud everywhere and don't go very far. Lock the center diff (and the front and rears if you have lockers) and the torque will still go to the front axle and pull you through any obstacle that would have gotten you stuck without the CDL.

So, other SUVs with part time 4wd (no CDL) do not have the option to lock the center diff, so they are always susceptible to the above situation.

I don't think there's one specific thing that makes the Disco bad *** though. The CDL and full time 4x4 are huge factors, the 12-14" (or some ludicrous amount) of stock wheel travel helps. They're really just built to be brutal off road machines.
Except when they put out models that dont lock the diff...
