Differential Locker?

Took my ML for a camping trip and got stuck in some lose sand. Luckily I got winched out by a friendly Tacoma driver. It was pretty sad that I got stuck on such a small gradient sandy incline. I recently got brand new Michelin defenders mud/snow tires. So not much help there. Low range didn't help either. So of course I checked the search function for anyone installing a rear diff locker and seems like no one has? Is there a reason why this hasn't been done yet?

Probably because it's in the same category as adding a turbocharger to a gasoline-powered ML. Expensive, unnecessary and ill-advised. Yet there are dreamers who want to do this stuff, just because.

Modern electronic traction-control systems have made diff lockers obsolete.

Did you deflate your tires, to under 21 psi?

Not sure that will help you. The traction control will give you the same effect, but if all 4 wheels are spinning on ice or sand, it’s winch time.

Should of turned off the ESP in sand. Probably would of come out. As DrX said tyre pressure is also important in sand I use to run about 15psi.

Unless you're obstructing traffic, on soft sand there are other strategies before deploying the winch.
  • Deflate your tires - if you have the balls you can go down to 12 psi for tubeless. Make sure ESP is off.
  • Dig from around the bogged tires, insert sticks or firewood for traction.
  • Jack up one corner, putting wood under the jack. Fill in the hole, add water to compact the sand. Repeat on opposite corner.

There are some sand driving tips translated from German at this link:

For next time.

Obsolete? I beg to differ. I'd much rather know I have power going 50/50 front/rear like the old school t-cases. And a rear locker will get you over some obstacles in 2wd that you cant do in 4wd. These aren't rock crawlers but I'd be ashamed if I got stuck like that LOL. I'm working on a fix because that will not be me.

The ML will be awesome in snow with independent front and rear suspension. I'd blaze trail for SAS rigs because all they'd do was bulldoze snow up front and I only had my rear axle dragging.
