Still, thanks for helping me, and DSM thank you too!! IM SO HAPPY!

 

Ok, Splain to me why a rear axle has to breathe. Edumicateme.

 

Cuz it's kind of hot and stuffy under there *gasp*

 

A differential breather is a vent to the outside air, covered by a cap that helps keep debris out. This breather is usually in the top of the axle housing, above the differential. The breather is necessary to relieve pressure in the axle housing caused by temperature changes. Without a breather, or if your breather is clogged, the pressure that builds up inside the axle housing will most likely push gear oil past your pinion or axle seals.

Since the breathers are located right on the axle housing, it is possible that they could be submerged if you were crossing a creek, deep puddle, or mud hole. The potential for a problem arises when you submerge the axle for more than a few seconds. The temperature inside the axle drops which causes the pressure inside the axle to also drop. This pulls whatever is on the other end of your differential breather into the axle housing. If you're axle is under water, it will be pulling in water. If you've pulled in water, you need to chage the gear oil soon, or down the road you'll most likely be looking at some damage.

The old girl has to have a gas relife valve, huh? Then stop feeding her chili and enchiladas.

Thanks for that google, Mark. Good info.

 

I had never heard of one before either so I googled to see if DSM and dodgestang were pulling our legs
