Had my first issue this week.Suspension warning light,Actuator stuck open.
At next start up it was gone.I have noticed that truck will sit pretty low after being parked overnight.Put in in off-road and pulled the level fuse.Next morning it lost no height but I have now discovered that the right rear always sits one inch lower no matter what?Possible height sensor?I have purchased a rebuild kit for compresser but a little lost on the height difference.

 

Do you have the nav screen. When my suspension started acting wacky it turned out to be a height sensor. My right rear. My offroad nav screen would show my back wheel dropping and moving all crazy with a red line.

 

I do but it did not show anything on the 4x4 screen. The warning seems to go away about as fast as it appears.

 

What happens if you drive over a curb with one wheel at a time. Does your suspension move slightly on the nav screen or does it bounce around?
