    Air suspension leaning

    Driver rear is leaning. Think the air spring is shot. Going to go ahead and replace them as well as the shocks. Any suggesstions?

    Is the pump running more often?

    Might try to "load" trunk with a few 100 lbs... Drive around block a few times, and unload.

    Two of mine "lean" a little every now and then. I've never seen or heard of a way to "equalize" or level them. I am dieing to hear of a way to do this. My pumps don't run too often.

    And I only weigh 200... So it can't be my fault!

    I originally thought my car was un-level in the very first place I parked it after purchase - gravel with grass. Spot wasn’t anything close to level. Parked Marauder on a close by concrete pad that was dead level (checked it) and Marauder sits level. Pump often runs when I first start Marauder, then rarely afterwards. Marauder typically sits for weeks between driving cycles - recent 5 week trip to Florida being the exception to date.

    Original springs are still available from Ford. Tasca sells reasonable. You need to diagnose though. Likely a spring but also could be a bad solenoid.

    Please please let me know if this works, and how much it cost.

    Now that you brought it up... My Red leans. Had new front springs and shocks installed... And while one shock was a little soft, rear still leans.

    If you don’t get new solenoids, at least get new o-rings for the solenoids. Springs should come with new o rings but just in case.....

    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    I bought Ford brand NOS on Amazon from Lasco parts for cheaper the 375. 375 sounds pricey to me.
