EZ Locker/Lockrite in the front only.

Front lockers are fine as long as both front wheels are turning at the same speed if your off roading and going round a corner it will be hard to turn
In my apinion front lockers should only be used when needed with the wheels straight

fully agree

we only use our front locker in a straight line - the co pilot flicks it off if there is a need to steer :ohmy:

our rear locker is a lock right which is pretty much fit and forget as it automatically disengages if you do sharp steering

don't know of any one with a lock right in the front that is also used on the road

So am i correct that a lockrite locks both 1/2 shafts together and will release one shaft if either wheel trys to exceed the speed of the other sort of the reverse of a LSD ?????

If you jack up 1 side you can spin the wheel and hear a light clicking as the locker releases. If you turn the prop it locks up.

On the road in 2wd the front diff isn't even turning so a locker makes no difference. A quick google suggests that fitting lock right on the front is fairly common in SJs as well as other 4x4s for this reason.

Yes that is correct, but only when accelerating. Simply put, it alway sends drive to the slowest wheel. If both wheels are turning at the same speed they lock.

When you are turning it drives the inside wheel. If this wheel starts to spin, as soon as it matches the speed of the outside wheel the diff will lock and both wheels will drive.

Where it differs from an ARB, though, is that as soon as inside wheel re-gains traction it *should* unlock. So you are only ever turning with a locked diff when traction is low enough to allow a wheel to spin. To me this suggests that you have a much lower likelihood of breaking things, and steering ability is largely unaffected.

The only downside I can think of is that you are doubling the amount of torque sent through the halfshafts compared to the standard open diff, but then any locker will do that.

If the surface was slippy enough you could turn full lock with a front locker locked and both wheels will turn at the same speed as a result which will allow the truck to turn to some extent but it will want to go straight on as a result of them going at the same speed.

The trouble is having a surface slippy enough to not put too much strain on the Jimny's already weak front drive line. Most people who have a front locker have extreme mud terrains which find grip well. Even normal mud terrains will likely find enough grip to break a CV.

If you're not running mud terrains, perhaps you should and then you probably will get a lot further without a locker at all!

A rear locker is probably more effective than a front one anyway and will take the pressure off the weak front transmission by maintaining momentum and preventing the need for lots of throttle to keep momentum, which causes breakages when the grip suddenly returns.
