I converted my buddies Montero Sport XS from the open diff to the air locker out of a full size Montero. Had a little compressor that went under the rear seat specifically for the air locker. Had no issues with it. It's not like a semi truck where you have a big compressor and air tanks lol

the stock montero air locker is extremely reliable. i was actually a bit surprised mine still worked after sitting 10 years.aaronatstate wrote: ↑Thu Jul 09, 2026 12:39 pmI converted my buddies Montero Sport XS from the open diff to the air locker out of a full size Montero.

I've pulled several Montero air pumps. Saw 2 pumps fail. Its just a pump and hold system with little line pressure.
The bladders in the diff tend to outlive them, but there is no replacement, so honestly a traditional LSD or Hybrid LSD is a better choice for most people.

Why can’t they be like the manual one? That seemed best of everything. Why did we complicate it?

Everything fails. Especially something this complicated.
You could always just install a "spool" and be done with it. Then again you create another issue further down the line.
Buy a new E-Hummer and be done with it.
