Thread: When to lock CDL

Probably the difference between a 100inch and 130 inch wheelbase but on long stretches of corrugated dirt I prefer CDL locked for more positive handling and throttle oversteer - plenty of drifting at Cape York fully loaded. Cheers

Just out of curiosity, how does the ATB react when wheels are up in air?

When that happens, I remember reading somewhere that light left foot breaking will make the diffs "lock up" to negate any unnecessary spin and keep you moving.

ATBs and TC are said to be the dream combo! Will probably go this route when I finally get the coin for it.

How many wheels in the air? I think it makes a difference.

But seriously, I lock my cdl on corrugated, soft or wet dirt. I don’t lock it on hard smooth dirt or wet bitumen.

+ 1 saving for ATB

Doesn’t make a difference. If the CDL is unlocked - just one wheel loose (in air) and the whole driveline loses it. With or without ATBs in place.

With an Ashcroft ATB in the centre, the CDL(ock) still works and can be manually locked.

On very slippery surfaces I notice serious understeer with my 110 when the CDL is locked - in some circumstances (usually only when the loud pedal is getting a workout, or the front end is unloaded e.g. uphill).

I tend to modify the wisdom that says “engage CDL as soon as leaving tarmac” to “engage CDL whenever it is possible/likely for wild wheelspin to occur, regardless road surface (“includes wet tarmac)”.

The longer the wheelbase the slower/more stable the reactions with any fore/aft load transfer.

Way out west I found that the short wheel base and round shouldered HT tyres had the rear end in the D2 wanting to climb out of wheel ruts coming up to cattle grids under severe braking. Sideways coming into a cattle grid is, err, interesting.
Too much speed had nothing to do with it.

When it gets a CDL and ATB it'll be interesting to feel the difference, but that's a fair way off.

Would having TC affect the need to lock the CDL, do you think?
