So I tinkered with the Spring properties with no luck. Then I moved onto "config joints" and learned a ton. So riht. These offer WAY more flexibility... Literally actually :-) So learned a ton but it still didn't fix the issue. Then i started figuring it may be a latent issue updating the variable that was the cause. Regardless i kind fo started from scratch, started with a couple cylinders connected, moved them around a bit to see the joint was working fine. Attached the top one back to my wheel and now it's working fine... I kind of essentially created a ball bearing and it's now working. Don't know what it was but sometimes wiping the slate clean gets it done I guess. Regardless thanks for the hook-up on Config Joints. WAY BETTER!
