anybody have any tips on driving with an aussie locker.sometimes at low speeds (parking lots) in turns it bucks and grabs.what causes it to engage or disengage?

Sounds like pretty normal behavior. Usually if you are light on the gas while turning, that will help. Also, avoid getting on and off the gas in turns. Why? On the gas, the outside wheel unlocks in a turn and the inside wheel drives. Off the gas and the inside wheel unlocks and the outside wheel locks up. It is those transitions between inside and outside wheel that causes the bucking, since the wheels are rotating at different speeds. So if you can coast into a turn then apply the gas smoothly one time as you come out of the turn, that will help to minimize the bucking.

You can use the clutch if you have a stick, that or keep constant gas or coast in, only real ways to do it imho.

thanks guys,just what I was looking for

I find that if I try to clutch in and coast through a turn it bucks from start to finish but if I give light gas and drive through it it's smooth as silk.

if I clutch before it starts bucking not too bad but if I clutch after it starts it gets worse

How long have you had it in?

got about a thousand miles on it
