Air Step

[Ralph L. Fullenwider]

Ernie:

The control valve could be passing air through the exhaust muffler, meaning
the spool is not seating fully or shifting fully. Of course an o-ring on
the spool or chamber could be bad too. Lots of stuff down there that can
leak. Another leaking point is the small cylinder that locks the step in
the out position. The cylinder rod gets bent and causes wear on the gland
nut and seals.

Safe travels,
