Do you lubricate the sway bar bushing mounted to the frame to avoid wear from twisting? Any product recommendations such as Silglyde, dielectric grease or some other rubber safe product? This is a 2001 Windstar van and it has a thumping sound, the link bars are also trash. I was able to push the sway bar side to side through the bushings indicating a loose fitment. I am posting this because there are people here with real experience whom can provide valuable information. I also read a similar thread on the Chrysler Mini Van and their failure prone bushings, the reason I'm going with Moog and not the cheaper parts.
