The Rear E-Locker

[The Mack]

Just go done extending the F/R difs, transfer case, transmission vents to higher level.

Does anyone know where the vent is for the rear e-lock is located at and could someone a pic?

I ask because I still have water getting into the rear diff after going through a water crossing. The water was only to the bottom of the rocker panels. The end of the vent tube above the rear tail lights. All lines are tight and dry at both ends.

Don't have a pic but if you crawl under your rig and look at the e-locker actuator you should see the small diameter vent hose coming out of it (it might be under the plastic wiring protector...take it apart to access the hose).

Could it be possible to get water into the diff though this vent tube on e-locker?

I have looked and don't see a rubber tube, but I do see a plastic tube coming off of it going to the under side of the drivers rear q panel.

So, is this plastic tube the breather tube? If so where does it end up at?

Did a search, not much info on the e-locker breather.

If its OEM then its probably like mine was: Hard plastic breather line. I replaced it with rubber fuel line hose. The actuator shaft does not vent to the diff/axle housing; actuator rod is sealed. So if you're getting water in the diff/axle housing its coming from: The position sensor, the breather or the axle seal(s).

I can only assume the breather is apart of the actuator...I assume it gets hot/cold quickly too otherwise no need for it...dunno for sure. When you blow on the breather line on the actuator no air passes.


Related: Here's what I know from experience: The rear diff breather was too small diameter for adequate air exchange on my '99 100 for how/where I drive; I've got $$$ receipts to prove it. As soon as I drilled & tapped it out to...I think 3/8" NPT with 1/2" ID clear hose run vertically up to a terminus at the rear tailgate upper/lower junction...all my axle seal issues, water in the diff, etc. ceased.

IMO you can not have too large a breather line...a desert racer clued me in to it. You'd be shocked how much oil, on say a 50mph run across miles and miles of washboard/undulating terrain, gets slung up in the breather tube. Ditto for seemingly copious amount of air volume that is exchanged hot to cold scenarios. So if the ID is too small that thick diff lube will sit there...especially if the breather line is run frontward along frame rail (horizontal) to the firewall like most of the 80 guys do it. I had diff lube clear up under the line sitting under my driver's seat...completely plugged.

When the clear tubing I used for the breather was new I'd see diff lube residue 4-5" above the breather port after a good hot run across the desert. Since there's a good 18" or so vertical before the line transitions to a short horizontal stretch its alleviated my issue. Proof enough for me.

Don't ask my why the 80 guys don't experience the same...dunno. It just solved my issues and that's all I cared about.

Thanks for this info. On my LC the hard plastic line goes to the drivers side rear bumper up into the body (where the jack tools are) with a wire loom.

Have looked for the other end of it, have not been able to find it. I guess if it goes up to the rocker panels I should not worry too much I guess. I don't plan to submerge my LC so water comes inside it.
