i replaced mine with moog balljoints from a parts website for about 40 bucks a piece. i remember it was pricey to get them installed tho.

the thing about balljoints is even if you look for ways to cut cost local shops are gonng get ya for it, but at least balljoints dont need to be replaced often.

i dont have a tire carrier but i believe it has a cert for grease? someone else can confirm this tho.
if it has one just buy a grease gun and do it in 10 minutes. or next time you need work on your truck, just ask them to do it complimentary. i get my certs greased all the time by shops and iv never paid for it.
