About 10 years ago, a well-respected suspension guru taught me a little trick to stop polyurethane bushings from squeaking and binding for a very long period of time. It's so bizarre and effective that I had to make mention of it. Here it is, in all its simple glory:
So who is this mystery suspension guru? It's actually none other than Mike Kojima of MotoIQ.com. He actually taught this to me when we were both active members in the Nissan community. Those days are long past, but I use this method to this day.
All I can say is that you should check out his site. And to extend my gratitude to the man who stopped that annoying noise coming from my wheel wells - Thanks Mike!
See you at the track.
