Yes I am having them all replaced on my bus right now
All 8 of the sway bar Bushings are already done The replacements are two piece Nylon or synthetic? so you need 16.
They are replaceing upper and lower Ball joints now, maybe they were not real bad but the rubber was all gone and they were rusted up pretty good I just wanted to get a good 12 yr replacment done and hopfully it will be good for another 10 or 15 yrs with the new style bushings,,,,,,,,,,,,,,,,
I dont like to scrimp on my steering components .)
