I make precision fit pins and delrin bushings. I purposely did not gun drill them for grease as I didn’t want to weaken the pin. A majority of the suspension load is on the lower arm, so this isn’t a place to experiment. I’ve even gone as far as Rockwell testing the originals and using the same material. This ensures safety in an impact causing the pin to bend not break. The material is more expensive to do this.
I’ve also made sure there is a degree of interference fit to compensate for temperature changes and break in wear. Delrin lasts longer than any Indian or Chinese rubber bushing and offers precision movement. I’ve installed many sets besides selling them and never experienced vibration in the steering wheel. Pushing the t bars all they way forward and drilling the socket for a set screw may satisfy some of people’s concerns. This is one mod that’s a nice upgrade from all the low quality rubber parts on the market. However, I respect the fact that upgraded handling is not everyone’s goal.
