This same thing just happen to me a few days ago. It's my 96 4runner (hunting rig) with the ARB in the rear - when flipping the compressor on it's good and turns off after pressure builds. Flip the locker on and it starts pissing air out of the diff breather and the compressor starts back up...
Do you need to use the FJZ80 hardware on the rear shocks? (metal plates that hold the bushings) and do the stock FJZ80 bottom shafts mount up to the lower 4runner stock shock posts?
Thanks!
