That vent helps allow pressure out that builds up in the rear end from heat,
to keep from blowing seals at your wheels. Blocking this vent or having it
clog with debris would cause this pressure to build up and likely push the
differential fluid thru the axle and into your brakes. This vent is a good
thing.
If you have a wire, (if it is the really stiff kind), it likely goes to your
vent control on your dash so you can operate and regulate your heat.

Subject: DML: Old 1989 Dak and axle vent hose
Thanks Tom and WilieR and Barry for your help. Its great to know I can find
it here. I am still wondering what is the axle vent hose for? If it has
a cap, why bother having a hose? (unless the I guess the cap is vented too).
Any way, I will be getting a new hose.
Also, that gizmo in the heater hose does not have a vacuum line, it only has
one wire that goes to the firewall. Thats why I thought it must be the
sensor
for the instrument panel temp gauge. Does that sound right?
Thanks again for help guys. I'll be bugging you all with lots of questions.
Cary
