well if the rubber grommet, or boot or whatever the tech. term is is busted. i would change it. bc it can get dirt, sand, or water in there and causes rust/wear down and cause it to pop out when you hit a bump or turn. if you have your car slammed out you might want to look into the extended ball joints; buddy club, m-factory, spoon, few more i think. but some of them have grease fittings in the that allows you to grease them for a longer life
