Can you fill us in on that? Is it just used to purge the line of oil if its gets any one there before it gets to the Solenoid?

Well, long story - short. I didn't get the result I was looking for.
I put the Purge Valve in. When I press the locker switch compressor pump the air in, and the locker ...... doesn't engage (at least imideatelly, will need to check how long it takes to get it engaged properly). When I push the switch off I'm getting air release from both: the solenoid and the drain line on the locker. I'd have to check where I get the oil going to (if its passing the purge valve).
Bad thing that we don't have ARB service center anywhere in East Coast. I'd of prefer to send the locker to ARB for complete check and re-build. All local shops are saying that they can order parts and change, but its my decision of what to change as they only instructed to change O-rings.
Another option would of been to take it apart myself, but I can't find any repair manual for ARB locker RD132. Any ideas of where I can get any?
If I do take the locker out and re-build, would I need to re-set the gears after assembling all back? Ring is bolted to the locker, while pinnion still sits in the 3rd member. I hope I don't have to take it off or remove the pinion nut, etc, as it sets with shims and crash sleeve.
How do I find if the issue is something worn out or its manufacture defect which apeared now?
Too many questions....too little solutions...

Bummer!
You don't have to touch the pinion to do a locker overhaul, but the carrier bearing pre-load and backlash/gear interface will need to be addressed and reset. The lockers themselves are not very hard to overhaul, just make sure you have all the needed parts in hand and it can take under an hour once you have it loose from the differential and ring gear. Good luck!

I'd guess that shipping the locker from Canada to ZUK is a no-go due to weight and Customs fees

If you do pull the locker, pay attention to how "tight" the locker feels coming out of the third, if the preload is too loose on the side bearings it can cause an ARB to leak, especially in a Toyota 8" (8.4") rear end. This is a very well known issue with Toyota rear axles and ARB's due to axle housing deflection.

That may be what is wrong with mine. I've had a problem where the locker is venting air out into the axle and then it is released through the axle's breather. Do you have any pointers to this well known issue as I'd like to read up on it. Thanks!

I don't have any off hand, but remember reading about it somewhere, I'll see what I can find. I learned this from experience, and by working with ARB's tech to diagnose what was going on with mine.
