That's great info, thanks! How might one go about finding out if a very knowledgeable person was not sharing what they knew? ;-) I'm a curious one—w/o much 4x4 experience to add.

I have a 9.5” 3rd member with SR air locker and 4.63 gears in it for sale if that helps you? Pm me for details.

Thanks, I'll keep you in mind. I'm still trying to find out exactly what I have so I can figure out exactly what I'd need. I think I'm also not 100% sure which part is 9" or 9.5". I was reading into it being driver's side axle (drive shaft), but you're saying 9.5" 3rd member. What exactly is 9" or 9.5"? Thanks!

For the assembly I'm selling, the Ring Gear is 9.5" in diameter. I don't know anything about the axles or driveshafts though so can't help you there.

I have 4.875 ratio gears, it’s stamped on the metal plate in the engine bay. What size gears would that put my SR at? Confused I am.

 

[jeep-N-montero]

All of the 3.0 SR's had a 9 inch ring gear as I stated, and the 9.5 inch will not fit the housing or axle shafts.

 

[d*rock]

Ah, okay. This all helps me know what to look for. Thanks, guys!

So the arb locker does fit in a 96 ls rear (9inch) ??? I have a front locker already ... having the rear one would make it just about unstoppable ...

Sorry I haven't check the forum for awhile. It turned out great. I was able to do some black diamond trails here in California.

The gen2.5s are prewired for rear diff lock. You just need the following parts from a 98-99 gen2.5 with lockers:

-Locker (get the whole pumpkin for ease of swap)
-Rear axle shaft (Drivers side, pick the whole thing for ease of swap)
-air pump (underneath middle passenger seat)
-Locker ECU (inside rear panel on the drivers side)
-Switch (lower center console next to the cig lighter)

Just run your own vacuum lines and viola!!

Hello. Can I run an after market pump like the ARB ones and locate my own switch? Thanks

Factory Mitsubishi locker? Not really straight forward with an ARB compressor. Mitsubishi locker uses 6 to 8 psi, the ARB locker uses around 90 psi. So using a straight ARB compressor setup on a Mitsubishi stock locker would blow out the locker diaphragm. Might be able to externally regulate (and buffer) it down somehow, have not looked into that.

If you can't find a Mitsu locker air pump you can use the vacuum pump from a Montero cruise control, it's the same assembly with a different bracket and a hose on the suck side instead of the blow side.

And much easier to find

SMART!! I tested my cruise control while driving a few days ago and it didn't seem to work. i need to see what's up. I would be able to just locate it, test if the pump portion works i can just make my own switch from it, ya?

Did you ever find out what was wring with your cruise control? Mine is also not working. Thanks
