I noticed today that my rear axle vent tube is just hanging there. Appears to be a clip on it, but I have no idea what it clips too. Could someone tell me why the rear axle has a vent and where it might clip back to?

My truck is a 2001 Ford Ranger 4x4 4.0 V6 Thanks, Mike

 

hooks to the cross member or frame right above it

 

I would imagine it's there built up pressure doesn't blow the seals out. It doesn't really matter where it's clipped up to as long as it's as high as possible and there is enough slack in it for rear suspension travel.

 

Rip that crap off, put on a longer hose and run it to the top of the cab... Or atleast the highest point you can reach with the stock one while flexed if you want...

 

I yanked mine and ran it up to the top of the bad behind the cab to keep the water out
