Sounds like control arm gone or front disc brake warping.Normally steering rack if leaks u just send it for overhaul, that is changing the seals, bushings and necessary machining if required, theres also a set of steering rack overhaul kit sold at spare part shop. Unless it still leaks after overhauling it then you should resort to used rack. Do keep in mind mechanical parts are repairable unless they are seriously damaged.
