Leaking from abc valves
Airmatic leaks off and the car is to low when you start it sometimes.
Right front sits down after 3 days sitting idle. Filtered fluid and changed filters several times. Finally notice leak from Steering pump with needed to be replaced at a cost of $4000. After repair, shop stated that it still sits down and may require additional valve block replacement, and additional $2800.
