I would opt for a big-ass rubber or plastic mallet.....

Air/vacuum systems can be problems to diagnose as there are diaphragms and seals that can be damaged in testing.

As there is a switch that depends on physical position, does it have correct actuator movement?

As something is supposed to move within the diff, is it moving??


I figured if the diaphragm in the actuator were torn, it would leak (easier to spot on the 80+ psi air lockers, though). Didn't seem to be leaking.

No idea if it's moving or not. I don't hear anything, but I did feel a tangible difference when it was pressurized...unfortunately, it felt like it simply stayed open, but was more directly engaged.

Check my last post, though...now all of a sudden, it seems locked...with no air pressure. I'm baffled. I need a <img src="/forums/images/graemlins/cheers.gif" alt="" />.

EDIT: Seems like I may have the same issue as this guy...http://www.4x4wire.com/forums/showflat.php?Cat=11558501155821&Number=1264868&page=0&fpart=6&vc=1 ...but it's hard to tell for sure. At this point I'm planning to pull the diff chunk tomorrow.

Can anyone confirm...it is, in fact, possible to leave either the brakes and/or e-brake connected, and pull the axles out far enough to release the diff? At least one person made mention that this was possible, but I'd love confirmation if possible. It would save me 30 mins at least. <img src="/forums/images/graemlins/kewl.gif" alt="" />
