Hi All -
I've been away for 3 weeks and came back to a very low rear end on the 6.9 (left and right).
When idling, it maintains normal height in the front (even left and right) and also responds to the raised H position at the front only.
There's no leak from back struts so I wonder if the back valve has stopped working while unused for that 3 week period? Or is it another easy fix?
Any help on the initial approach to the problem would be appreciated before I insert blocks and tow to...
