Bought a rack and pinion, it came to be defective and spent I 700 for install. Called rock auto they said I'd have to buy another one or take that one of which it worked just leaked like no other and being it was my only form of transportation I just bought another one. Well after I bought another I got deployed and didn't have it installed I came back and the car was stolen, so I called rockauto and they refused to take it back after explaining what happened. Also I requested a manager and I got refused that also!!
