One of the big draw backs to not having a full shop is that sometimes I have to guess rather than diagnose. I have a bad shake which starts around 30MPH and callms down similar to an out of balance wheel. It completely quiets down though if I take my foot off the gas. The 30MPH seems to be "the sign" for u joints or an out of balance shaft from two very serious drivers that I know.

Let me know your thoughts. I hate being a parts changer rather than a mechanic, but having no balancer, it would cost me more to rule out the simple stuff than to take my best guess and hope for the best.

Also, if anyone has any tips or time savers, I would greatly appreciate it.
