Usually it's front if you have a good Lim in the rear.
But if it's totally open or a Toyota put it in the rear - even better both :cool:

Though with a 40 that has an open rear..... and knowing the weakeness in the front diff of a 40 id definately go a rear first.....

Also, a locker is most useful when climbing. There's very little weight on the front end when climbing so a locker can only provide a limited amount of assistance. All the weight is on the rear so that's where it makes sense to maximise the traction on the end that's loaded up.

However, as soon as you have a rear locker you'll want a front. :D

Whether i had a lsd on the rear or not be it Nissan or the Toyota 1, i'd be putting it in the rear as when you lock it you'll always have 3 wheel drive, it's harder to steer with the front in so you might not get to use it on some tight knarly tracks

however with a tight lsd and a front locker you will have 3.5 wheel drive :twisted:

I normally advocate front first, but generally I'm talking to Paj owners who have decent rear LSDs. In a Toyota, I'd go rear first. :P

For the record, I don't agree with the "rear for climbing" argument either.

On a steep climb, with all the weight on the rear, the front is lightly loaded and less likely to flex well. Once one front wheel lifts, all front drive goes to that wheel - so the front wheel on the ground is getting no torque, it's doing nothing, and you're in 2 wheel drive, not 3.

Put the locker in the front and the front is at least pulling a little. The rear end, with all the weigh, is more likely to flex & keep both wheels firmly on the ground, so you're more likely to be a 2.x wheel drive.

At the end of the day you will buy one, doesnt matter which, and 2 months later and a dozen tracks and you will buy the other one....

Lockers are only good in pairs :twisted:

Front first if you've got a decent rear LSD. Unfortunately you've got a Toyota so it's got a terrible LSD so you'll need it in the rear.

cheers

Yep it's called a Diff lock!

The comment about Nissan LSD's
A mechanic once told me the ultimate truck would be a Toyota with Nissan Diffs - maybe there is something in this :?

Plus Nissan gearbox and transfer case. MAYBE a Toyota turbo diesel motor, but TD42T with some wise mods makes as much power, and more reliable. However, std Toyota motor better than std Nissan.

Not unless you are prepared to change diffs which will mean change widths which will mean change front diff !!!!!!!!!
Locker rear & as Screwy said front will follow 12mths down the track.

Just my 2 cents.

I would go front locker.

I find when climbing hills a front locker helps to climb over steps / ledges. Having a rear locker, while good, only seems to push the front wheels harder into the ledge or step.

I have had various combinations in various cars (40 series, 60 series and now 80 series - rear only in the 80 at present only because I pulled one of the lockers from the 60 before selling it) and found the front locker to make the biggest difference.

Tom.
