I know this has all ready been done but oh well whats alittle more information on the subjects...

Items Used:
(8') of 3/8" Air hose ( like what you use for a air compressor)
(2) 3/8" hose clamps
(1) 1 1/2" Nipple
(4) 10" zip ties

2) 6" zip ties
(1) factory rear diff breather ( you should all ready have one)
(1) tube of sillicone


1- Un-screw the factory breather from the diff tube, and screw in the 1 1/2" nipple after applying a bit of sillicone and tighten.( i used sillicone to be on the safe side you could also use pipe sealent)

2- I then installed the air hose over that nipple and looped the hose around so that there would be enough slack that the suspension could drop without fear of pulling it off. After I thought i had enough I zip-tied the hell out of it to a rear cross bar, and headed toward the right rear tail light. I figgure that if the breather went under up there we would have more problems then just the axle.

3- I then removes the right rear tail light and fed the hose up towards the tail light housing, and zip-tied it as need be. I then cut the extra hose off and re-installed the factory breather on the hose and clamped it.

4- before i buttoned everything up I did a sag test to make sure everything would work the way I wanted. It appeared I had plenty of hose it never even thought about binding.

I ran the tube to the right rear taillight. it's the highest point to get it without being seen. plus if you get your taillight under water, draining your rear diff will be the least of your problems.
