just replaced both of my swaybar links.. wow, what a difference!! The one on the drivers side had started to make a little noise, but I didnt really notice a difference in handling... until i replaced them and WOW much tighter. with lots of VXs hitting 100k, a lot of them could probably stand to be replaced. pretty easy job too, i didnt even take my wheels off (but would be easier if you did..)

all you need is..

14mm crescent wrench and a 14 mm socket/ratchet.
penetrating oil helps too
i needed a helper to hold one side of the link in place while i loosened the nut, but probably not even necessary if you take your wheels off

i got the set for $57 bucks from my local napa
