Polyurethane bushing squeak

Bewy said
The factory 'knew best' when it came to using rubber bushes in Mopar suspension systems.

If you want to race your car on a race track that does not have potholes/speed bumps etc, by all means use poly.
Rubber bushes [ for the factory ] are only cheaper because of the volume produced, compared to poly.

The factory used whatever the bean counters told them to use so the car would get past the warranty and that was IT.

It‘s unreal how people think rubber is all that. It’s JUNK. It starts to degrade from day 1.

Just like an elastomer damper, rubber is cheap.

I’ll take good over cheap any day.
