Seems you have not the faintest idea how a Detroit works.

I have an 80 with part time 4wd and put a lock right locker in the front and it is great. They are actually automatic unlockers when the hubs are locked so you can't forget to disengage them but you can still get windup. They are much cheaper than other lockers and mine have been in for 130 k kms without the slightest problem. Highly reccommended gear.

I went with the Pro locker in the rear, been in for two years and not one problem. I think you are spot on with thinking that manual would be better than auto locker. Yes it would be good not to have to think about when to put the locker in, however I was in a mates Hilux that had auto locker in front and we got caught out by rain on a desert track which turned it slippery to boggy quite quickly. In 4wd he couldn't keep it straight due to front being locked and no way of unlocking it due to not enough load to cause the unlocking action when turning due to the slippery mud. We had to go back to 2wd which meant lots of driving until stopped and then reversing a bit and having another go at ploughing through. We were both pretty sure we woulldn't have had the problem if we could unlock front without disengaging 4wd.
PS: His next vehicle has ARB lockers front and rear and he has had no end of trouble with the O rings failing which is why I went the Pro lockers. Sometimes its good to learn from other peoples problems.

I had front and rear Detroit lockers in my part time 4wd 80 series, they worked perfect.

Cheers Steve.

80seriescruiser,

If you are going to fit a locker to the 80 Series fit it to the back. You will get more use out of it going up and down steep hills and still allow you to steer and drive where you want.

A locker in the front will hardly be used and the vehicle was never designed to have the primary drive on the front, if it did they would have a LSD in the front as standard.

Thanks for the replies.

With a Lock-Right fitted to the front diff only on the 80 series, when I haven't locked the hubs in, the Lock-right's wont be turning will they?

ie. The Lock-Right is only being used when I lock in 4WD mode?

So when I am driving around in 2WD I will notice no difference in the steering performance etc?

Apologies if this sounds a novice question but trying to understand how it works.
