i got all new UPR suspension waiting to go on after i fix my quarter. part of the new suspension upgrades are the UPR uppers and lowers with urethane bushings, but i still need to get axle bushings for my uppers. i was thinking about getting spherical bushings, but heard they can be pretty harsh for a daily driver, as well as noisy. but then i've heard otherwise. what is everyone's opinions on these for a somewhat daily driver?
