So I just bought this car last month and heard clunking so I assumed it needed ball joints so I replaced upper and lower on the passenger side and the bottom ball joint immediately starting spitting grease and the knocking started up again. Did rock auto seriously send me a bad ball joint? Is this common? Also I’d like to note that the joint itself only came with one bolt for the mounting hardware. It requires four for the job. Lmk guys thank you!
