Thread: Puma diff lock not engaging

Has anyone put back or front lockers on as a separate way of locking just one diff?

The dmax has a fair bit of torque and if it is an auto it'll fly up sand with the dsc off. Thats the only time a defender will come second...😎

Lots of info here and elsewhere about locking front & rear diffs. I have an Ashcroft locker in the front and an ARB locker (unfortunately, thanks to previous owner) in the rear of my 130. Not much will stop it.

Exactly right. Don't wait til you are in strife at, or in, an obstacle before engaging the CDL. Once you find yourself unable to continue before you engage the CDL - you may have to do a bit of back&forth etc. sometimes you'll be lucky and it will go in first time.

Better alternative is to just ease the selector over, while driving along, before you find you cannot proceed, and hold it there until the light comes up.

Ah, I was waiting until i stopped to engage the CDL. I will definitely do it now as I am moving, probly at slower speeds though. I dont know that it should/could be done at more than, say, 10-15 kph.
We are going down south this weekend starting at Lake Navarino, and I know there are some gorges down there. Will be a good test, not that it needs testing, just perfecting.

Engaging while moving is fine. Just make sure you are travelling relatively straight line and not spinning any wheels at the time.

I engage CDL on the move....at what ever speed I hit the dirt at

Am I reading it right that you are asking engage a locker instead of CDL? You won't gain anything, CDL first than axle lockers after that.
