FAQ

Q: How long does it take for poly bushings to break in?

A: Regardless bushings don't have a break in period like other parts and shouldn't make noise after having them replaced.

Q: Do you need to lube poly bushings?

A: Polyurethane bushings are a great upgrade from rubber and plastic bushings, but you need to care for them properly. You do have to grease polyurethane bushings if you don't want them to squeak a lot. In addition, greasing the bushings sooner rather than later will help your bushings last longer.
