people are gonna talk up the Moogs i do believe.
i'm not a fan of 100$/piece ball joints. i saw Pooks 'moogs' grenade themselves in a year on a stock cherokee. they are life time warranty though.
i am running the cheap ones from autovalue. was like, 100$ for all four........ that said, i carry a spare set with me on the trail. so far though, they're holding up......... if i had the coin at the time i probably would have done moogs cause many people swear by them........ but i also did bearings, ujoints etc at the time. it got costly quick.
