About a month ago I got new front air struts and rear bags from Westar. The car road great and it was nice not having the check air ride message come on at free way speeds.but over the last few weeks I've noticed my compressor running occasionally at traffic lights or when getting off the highway. I thought it was just because the car lowered itself, then I noticed that when I park the car and come back after about 3 or 4 hours the car is leaning to the drivers side. I checked and the drivers front strut is leaking down. Considering the strut is new but came with a used looking solenoid, I'm thinking either the solenoid it's self is leaking or when I removed the solenoid to hook it to the air line then put it in the strut maybe I caused the O rings to leak. I've heard of guys using A/C o rings to replace them. Does anyone know what size they are? Paying $20 for 6 O rings from one of the air strut companies seems stupid when I can get them all from the Autoparts store for a dollar or 2.
