While removing the hubs to take in for new bearings, i finally had a look at my ball joints/control arms... i realize they should be able to spin freely, but im wondering how much play is considered ok when talking about ball joints. i will replace my drivers side control arm as the ball joint boot is torn, but the passenger side isnt torn just older looking, and has cracks in the boot, again not torn. im wondering about up and down play vs side to side. any idea whats ok and whats not?
