I think nearly all aftermarket sway bars use poly bushings. The RRM/Progress ones are black so they might be graphite impregnated?KuroNekko wrote:I don't recall the RRM sway bar bushings being polyurethane. I thought they were rubber just like the OE ones. Regardless, I did some research on the best lube and found that Super Lube is most recommended for the reasons you stated. I live really close to a Home Depot so I'll pick it up there. I just really hope this is the cause of the noise.
From Progress:
Update: I gave my sway bar bushings a much needed lubing. See here: http://www.kizashiclub.com/forum/viewto ... 396#p36396Our Sport-tuned Sway Bars replace skinny OEM bars and rubber bushings with larger diameter alloy steel bars and polyurethane bushigs.
