Bought rear air bags for my 98 lincoln town car about 1 and half yrs ago also bought air ride compressor at the same time one air bag is leaking and has caused compressor to start making all kinds of noise just don't understand how original air bags lasted for 20 yrs and these lasted less then 2 yrs never a number to call for help here. I have dealt with rock auto for awhile but not sure I'm going to keep dealing here if u can't supply a number for someone to talk to about this problem .
