Lowering the tyre pressures gives you more traction/floatation and lessens the wheel spin considerably and helps to reduce the damage done to tracks by running on hard road pressure tyres.
The same goes for engaging 4WD or CDL.

I have driven a lot of tracks, with zero wheel spin. I would consider lowering tyre pressure in perhaps 5% of cases. For comfort, more than anything else.

is it just me,,
or is there something wrong with a car that needs a big right foot to engage traction control,, yet aparently breaks the transfer case if you do it without the cdl engaged??

IMO nothing will happen to the transfer box cos TC was conceived to work instead of the CDL that's why on early modells when CDL is engaged TC is inhibited and on the late ones with the uprated SLABS the TC is addapted to the CDL and rarely comes on so if you want to lock the CDL dont expoect too much from the TC or if you want the TC to work well dont lock the CDL, keep constant rpm around 2500 and it will do it's job

I think that it has to be argued that way, Rick. I reckon Dave Ashcroft knows more about the LT230 than any ten people on here, He says they fail, and yet they survived with only TC. Of course, we don't have any figures on actual failures. Can't see LR releasing those.

I have to say that IMHO it is spinning a front wheel which is the typical situation that kills centre diffs . It affects cars without traction control more but you can still do it by being an idiot and keeping your foot in it, or going 4wd with the 3 amigos and keeping your foot in it.

I bought a transfer in bits to get the nose with the selector, and the thrust washers were all stuffed and there was a heap of brass swarf in the little sump casting . So the only circumstance that I could see that happening is excessive wheelspin and /or failing to change the oil .

My Centre diff at 170KK had pristine thrust washers and no swarf which to me indicated the PO had never taken it off road which I believe from talking to the PO..

So I think it is still possible to kill a centre diff in a D2 but you have to be a bigger tool than in a D1 or RRC.

Hey guys,

I fitted the selector mechanism without much difficulty. Had to cut a bigger (square) in the top black cover plate (to accomodate the sideways movement of the lever, as per the link someone posted on this thread, thank you) . Adjustment of the cable was easy enough.

However, I looked for the CDL switch but could not find it (or maybe one beer too many). I have a bunch of loose connectors but no switch (beer and whisky don't mix). That however is not a problem to me, as I prefer no interference from the traction control electronics. When I engage CDL I have no indication on the dash (obviously because of the missing switch) which is also fine. I struggle a bit to go from HR to LR (even before I hooked up the CDL) and back but that is normal as I have experienced the same difficulty with my Toyota's.

Here is my question: Because I have nothing telling the traction control that the CDL is "active" (in my case it is a purely a mechanical selection), I take it that the traction control would want to "interfere" while CDL is engaged?

Also, my 3 Amigo's are permanently lit up, does this mean that the traction control by default is not "active" because of the 3 Amigo's?

Lastly, can someone point me to where I can get quality wheel speed sensors to try and kill the 3 Amigo's permanently (I have rplaced the shuttle valve and solenoids allready).

Thank you guys.

The tracks you drive on must be a walk in the park.
