I was told by the shop I go to that my rear air compressor was blown, I could hear it running but it wasn't going up much. I bought springs but had to next day air the shock's. so I went back to get the truck until I get the shock's, but the bag's are up and riding fine. is the shop just out to make money now or what? I've been going to this shop for 4 years but there's a different service writer than usual. I was supposed to take it back today but I'm not sure what to do.
