300SD AC Leak

[Fuzzball]

Well, I finally got a general idea where my AC leak is on the 84 SD.

I can hear the gas leaking from the front of the car.

Last year I went without air...not gonna do it again this year....

One day it just quit working and it turned out it was out of 134a. Added full load and it lasted a single day (but made a big difference on that trip!).

I can't imagine what happened. No wrecks...nothing slashing into parts, just started leaking. Now I can hear it coming out when I add some.

Anyone got an idea what might be leaking? Is there something that is known to just start leaking?

Sure would like to fix this without having to pay triple digits just to identify the source.

We've already had triple digits here...it's really time to get this done.

thanks in advance!
