Few weeks ago, I was under my truck and squeezed the driver side rear shock bellow. Hissing noise. I assumed, shock bellow is leaking air, called it warranty and received replacement shocks FOC Thursday. Yesterday, I started replacing it - shock is only 8 mths old - and found, that air comes out of the nipple attachment. More specifically, from a plastic elbow, where air line comes out and bends at 90.
I did further investigation and could not determine anything that, actually, seals air on the nipple.
Even if line attachment was made snug on the nipple, air still bleeds from where the line enters into the elbow. There is no seal, O-ring, etc, neither on the nipple nor in the elbow itself. It just loosely clips onto the nipple and that's it.
I work professionally with vacuum sockets and know, what it takes, to seal air bladder.
I sealed that line for good but I have question now. What exactly seals the line connector to the nipple and, it has to be an AIR TIGHT seal, what is, by far, not easy to accomplish on anything, least to say - on an up and down moving shock?
I'll check on the pass side one too but, last time I did it, there was no hissing noise coming out of that one.
