    All D1's have a centre diff lock, it is the D2's that some of them dont have CDL's.

    Try sliding the High Low Lever over to the left and look for the pretty light on the dash which says that it is locked.

    But dont use it on hard surfaces and dont use low range with out enguaging it.

    actually Id like to hear your reasoning behind why you don use low range without it as well...

    I'll offer my suggestions.

    Generally when you need low range (off road) you would already be encountering wheel slip/spin. I feel its a bit kinder on the transmission if it isn't subjected to as much shock loading such as when you lift a wheel and then come back to earth with it unlocked.

    Of course there are plenty of times when low range unlocked is appropriate, ie. slow speed work with a trailer. etc.

    I don't think mcrover was making it compulsory but maybe thats the way it came across.

    When bought TD5 D2 manual gear box it did not have a CDL fitted. The gear box had the cabability of CDL but did not have the linkage in place.

    The linkage was retro fitted.

    Don't know whether it is possible to retro fit the linkage on a V8 auto. Would be worthwhile getting some one to have a quick peep at your box and letting you know if it can be retro fitted.

    Regards

    I put the CDL in when im scared like a little baby.

    Its the "please help me god" gear.

    In actual fact, Ive NFI idea what it does... just makes it harder to steer.

    i know it locks the centre diff, and I know people say its not the same as diff locks. people still fit diff locks to cars with a CDL.

    so what does it do?

    Because it puts too much torque through the cross pin in the centre diff.

    If your backing a trailer up a driveway or the like and only for a short distance it is better to use the CDL as it will take a lot more than that pin.

    It is only a 2 pinion diff centre in the centre diff and I have seen 3 now that have either broken the pin or cracked pinions in non 4wd applications, 2 were backing trailers, 1 car trailer up a steep driveway and 1 caravan through a drain into a site and 1 that was just full noise stupidity taking off from the lights in Low range no CDL and the inevitable happened.

    I didnt do the repairs but I did see the damage done.

    Does that cover it
