Personally, I prefer a locker you have some control over like the ARB.

It's nice to be able to choose when they go in and out... an auto-locking diff can be a nightmare in snow for example.

I know people that run auto-lockers without too much trouble, but I went for an ARB in the back and a Limited Slip in the front.   Does me OK, and it's controlable.

ARB was from Devon 4x4, LSD was from QT services.

Hi,

I have Tru-Tracs in Piglet front and rear - once you get used to them, they are fine. The first 30 seconds though.....<shudder>

<grin>

IMHO, the best is LSD locker in rear,KAM, and a Truetrac in front. The problem with lockers in front, is you cant steer when locked in very well, if at all.
Not heard of problems in snow with truetracs, but i think we are in for some snow this year, so i will be forced, purely for testing purposes, go for a little drive. :lol:

Lofty,

The problem I've found with auto-locking diffs on the rear (in a similar vain to the front) is that if they lock up, it makes steering a little interesting... since it just wants to go straight on.  Hence my preference for something with a positive action in the rear.   I find the LSD in the front (no full locking) works well as a compromise on and off road, and doesn't hurt the steering much.

Ah, i believe muddy and i are talking at cross perposes, i am talking about a truetrac diff, which is a torque biased diff, which balances drive automatically through worm gears, rather than a auto locking diff, which is also made under the Detroit name, which i believe you should never put in the front axle.
The truetracs are the same as a quaife design diff used in rally cars, this helps traction, and removes a lot of the torque steering in front wheel drive rally cars.
Another thing which Ashcroft dont normally tell you untill you buy a truetrac, is you must have a metric diff housing, and you also need a spacer for the crown wheel, oh and what spline type on your half shafts.
I love them to bits, you know you got max traction, and can still steer full lock. :P

You might be right Lofty..

To clear things up....    I run a TruTrac torque biasing diff in the front which provides a pretty good limited slip action... and an ARB air operated full locker in the rear.
