Re: lil vibration
Always start a vibration diagnosis with wheels and tires. I'd say it's probably the cause 95% of the time. You say you don't drive it much, so make sure the tire pressures are good (at least 35 psi), more if your parking it a really long time. The more pressure you have in the tires when you park it, the less it'll create a flat spot. Just make sure you bleed it back down to normal when you go and drive it. If it is a flatspot, and only a flat spot, it should eventually go away after a good 15-20 minutes of highspeed freeway driving. If it's still there, then I'd recommend getting your tires balanced. While they're getting balanced, they can also be inspected for bent wheels, tire separation, or excessive tire runout. If you really want to check to see if your wheels and tires are good, you can up for a road-force balance. Most Discount Tire Co.'s have a road-force balancer. It measure the variation of stiffness all the way around your tires. And in many cases, they can match mount your tires to your wheels to help eliminate road-force. Make sure if you are getting balanced, that you do it at a shop that your confident they will do it right. What I've noticed with these wheels after balancing a few of them, they don't really want to be mounted straight, square, and true onto the balancer. For some reason, I haven't figured out exactly why, you have to put more consideration in mounting the wheels squarely on the balancer that you would need to on most OEM wheels. Just try to make sure whoever's balancing them, knows what the hell they're doing. BTW, if you see someone throwing the balancer cone on the front of the wheel, instead of behind it, have someone else do it.
