the bags leak when they get old.they sure as hell do ,and just try and buy a replacement set at a fair price. as a matter of fact the part number must be a closely guarded secret because no matter how many times anyone ask's around here you never get a response. I need a set for my 03 and even with my discount the price is too high.and I can't find who makes them for GM. and there are no after market bags yet. GM parts direct doesn't list them . I buy bags for ford expiditions for $145 a pair all the time . some times I think I might just put coils in .
