    How many very fast 2wd rally cars you see these days?
    CDL locked on any loose or slippery surface without a doubt improves the handling and predictability.
    Even can be used on patches of wet tar as required if it's slippery enough. Especially those on muds eh? [which in some very small way also slightly offsets windup thru tread squirm]
    On gravel etc, it will help alleviate tramping on corrugations and allows predictable traction. With an unlocked the power transfer fore and aft gives unpredictable handling.
    Mind you, popping the bonnet must be a PITA. Sounds like you want to look at a new mod to it to bring it inside the cab

    I use my cdl only when things get muddy or very loose, as far as wind up is concerned if it takes more than half a metre then its time for a service. I've driven long distances (60 to 80km at freeway speeds) at high speed with cdl on, once the transfer linkages were jammed the second i snapped the rear drive axle and both times i only had to reverse about a metre. as far as wear is concerned, better to wear out than rust out dude! If ur still worried, get diff locks man, ull never have to worry bout a cdl again aka YouTube - mudsloth's Channel

    if it takes more than a coupla meters to "unwind" then its time for a service or ur possibly ur linkages are jamming, i have driven with cdl engaged for long periods of time at freeway speeds twice, once when the selector was jammed and again when i broke the rear drive axle. both times the cdle disengaged within half a meter of reversing. As far as when to use it, well, do u think ur going to get stuck? Hehe...get front and rear diff locks and never worry about the cdl again aka YouTube - mudsloth's Channel

    Correct. It's time to get dirty.

    that's as long as you don't let things get too slippery, hey mick?

    if you chock your wheels before you jack it up, like you should, then stick it in neutral and take off the handbrake, this will relieve the tension in the drive train and you will not get any spinning of the wheels. if you are on a big slope then you may need to reapply the handbrake before jacking, but in most cases you should be right.

    usually only takes about 50m at highway speed to disengage (vacuum CDL), i just back off the power for a sec so there is no torque working through the drive train and out she pops!

    The centre diff pinions are steel on steel and their thrust washers are copper alloy. These suffer wear from poor lubrication if there is appreciable wheel spin with the centre diff unlocked.

    The centre diff is not particularly robust and is intended for on road (relatively smooth, high traction) use - hardly suitable for off road.

    On loose surfaces or uneven terrain where any wheel becomes lightly loaded, any torque wind-up will release when the centre diff is locked - no different to 4x4 with no centre diff.

    IMHO there is nothing to loose, and everything to gain from locking the centre diff offroad.
