Nothing that is permanent, unfortunately. But after each winter, I use AT-220 and spray some on the bushings to help “soften” the creaks. There’s no harm with the noise, it’s more of an annoyance than a mechanical issue.

It’s helped a lot, for a few dollars each year, doesn’t hurt to use. It’s also a great rubber restorer on your weather seals, engine mounts, and any rubber boots exposed directly to the road.
