..............When I run the rear locker the cab of my 4runner smells like gear oil and I can hear it in my vent tube coming off the third. Also the compressor will run nonstop. This doesn't happen when I run the front one. here's my questions for you guys. The other day I was out playing around in the rocks and got hung up pretty good. my buddy's said that it looked as if neither of my lockers where working. #1 Could this be because my compressor is running nonstop because of the rear that I'm not getting enough air to engage them? The steering felt difficult as if the front was engaged but both tires where not spinning. Neither where both rears. #2 Any ideas what's going on with the rear that's causing the smell in the cab and the compressor to run nonstop? I keep hearing possibly a bad seal or Oring. Last but not least #3 where is the best place to get the seals/parts to fix this?................
With the comp running non-stop you either have a leak in the rear air lines, chewed through the copper tube w/the ring gear, or a blown seal.
An o-ring issue would be at the diff housing, it would cause the comp to run non stop since the line wont pressurize, the extra air around the diff could cause the smell inside. However if you have can feel the air coming out the diff vent line, then the leak is inside the diff, either a blown seal or you somehow chewed through the copper air line that runs close to the ring gear. If you have both the front and rear ARB's plumbed off of the same airline, neither will engage with an air leak.
I would call all ARBUSA, and talk to the tech department, they may have an idea of what the issue is depending on the production date of the locker, they will have all the parts needed.
