    Does this mean that you are selling the Defender?
    Most 1996 and beyond Surfs have 4h, 4hl and 2l. I believe 4HL is 4 high locked, ie center diff lock. Thats my understanding.
    Let me ask you this, dont most 4x4s have a center diff lock? is that not how 4x4 is engaged?

    Yes its engaged by a central differential, but a center differential with a LOCK is some thing different it tranfers power to other wheels when one is slipping or loses traction.
    There is an article by Janj in great detain about this and other features on the forum.
    I am looking into buying a 2002 Surf with a 1KD engine .

    2002 is a good buy..but why not move on to the new shape patrol model?

    Agreed that the diff lock would actually transfer power 50/50.. front and rear.. what about other 4x4s.. is the differential not locked? they don't transfer power 50/50 front and back? or do they shift ALL power to the wheel that has least traction?

    I always thought that on part time 4x4s, the differential got locked once the 4x4 was engaged...i guess i was wrong?

    Differential lock is independent.
    4X4 when engaged will infact turn the 2 shafts through transfer case.
    Now if vehicle has Rear Diff Lock then the 2 Rear wheels will rotate at same frequency if it is locked, if unlocked then the wheel with less traction will bear the brunt.
    Same is with Front Diff Locks.
    They are ideal in Mud as it will tend to slip the tyre & if it is Diff Locked then the two Rear & Front Wheels will have same frequency rotation

    Yes exactly as baigaqeel put it.
    The newer shape is more expensive and above my budget and correct me if I am wrong , also doesnt have low ratio gears. The 4wd is engaged by a electronic switch.

    Thanks. I clearly understand the rear and front diff lock workings. In fact I have a mechanical locker (aussie locker) installed on my surf.
    Its the center diff lock that i am bit confused about. 4x4 when engaged, ie 2 shafts connected thru transfer case, is that not same as center diff lock being engaged? if not then what is the transfer of power on a normal 4x4 without a center diff lock and what is the transfter of power on a 4x4 with center diff lock ?

    @ Sajidd, (OP sorry to barge in), you are not wrong, in part time 4X4 when 4H or 4L is engaged its essentially same as centre diff locked in fulltime 4X4. So obviously with part time 4X4 you don't get to drive with unlocked centre diff and hence strongly advised not to use onroad where there is high traction, because of risk of wearing out you tyres and transmission quickly because of diffrent tyre rotation on turning the vehicle.
