if the sway bar end links are original, time for those to go as well as the inner pivot bushings.
the end links are sort of hard to feel looseness at a stand still, as they are almost always in a sort of binding condition.
get them off, and you can REALLY feel and see how bad they are.
most new ones also have grease fittings to keep them lubed. i have used those as well as the sealed factory types, and both worked well.
as said, the hardest part is getting the retaining nut off, especially if rusted.
you can do it DoC. we got faith in ya !
