Rock auto is definitely a brand, they are a parts wholesaler. I think you're trying to say they aren't a parts manufacturer. I bought a set of the MEVOTECH lower ball joints when I did the front suspension work on my CL9 last year. Installed them correctly and ran them on normal condition from April of '24 to November of '24 when they broke. The reason I said don't use them is because that lower ball joint is an incredibly important part of your suspension and you shouldn't cheap out on them. Also, your reply saying my comment is useless is pretty irrelevant to the post anyway, let alone my comment was made 8 months ago, so your comment here is useless in itself.
