Try it without the thesaurus.

OEM torque arm suspensions, much like OEM triangulated 4 links, use large bushings for NVH. That's noise, vibration and harshness.

In a handling setup, this is the handling forum isn't it, NVH is irrelevant. You'd use delrin for the bushing to minimise unwanted movement. To further minimize unwanted movement, the u joint and the pivot need to line up.

Do some research on torque arm suspensions.
