Bests & Worsts Reviews from Amazon

I installed these parts on a 03 z71. First thing I noticed is they sent me one upper control arm with a serviceable ball joint and the other was not serviceable. The other thing I noticed was the lower ball joints had grease fitting that pointed straight up so if you have a 4wd you will need to swap out the fitting for a 90deg or you will not be able to service them. Quality??? Only time will tell they seem to all fit ok. Update 12 thousand miles later and these parts are terrible. Ball joints are bad the new tires I put on along with these parts are now cupped and bad. Everything I purchased for the front end from Detroit axle is bad I purchased there hubs too witch I need to replace as well. Best advice I can give do not buy there parts!!!!spend the extra money on quality parts. 8/10/17. Just had the passenger lower ball joint break. Luckily I was just backing a trailer up and going down the highway. Please do not buy these parts, very dangerous. I'm currently changing everything out.
