New X owner and Air Suspension ?

[jus4kixx]

Hello all, new to forum and owner of an 04 4.8is (160K). Passed through family (we'll see if that tells if I am liked in my family)

I know the air struts were recently replaced by previous owner 15K miles ago, and last week the front driver side is sagging. In NJ and have already ate two major potholes on that side of the car.

I was getting ready to do the soap and water test but wanted to ask a quick question. The bag doesn't appear to be leaking. If I raise the car to the highest, it raises just doesn't go as high as the other three areas of the car. I left it high over night, came back out this morning still at height it was last night. Listened to the pump work this morning, came on for a few like normal and then off. I didn't keep running like was trying to get the front driver bag to stay up.

I think I read that if leaking, likely bags, if not leaking but sagging likely electrical. Just looking for a little direction.

I have an indy if needed, but also interested in absorbing cost when I can, not afraid to do my own work with guidance. Just completed my first project of replacing LCD screen in Nav unit. That was fun.
