U joints in outdrive bad, gimble bearing or something in outdrive is bent

What are the proper steps to determine if ujoints or gimbal bearings are bad or to eliminate what is good???

You'll need to pull the drive and take a look at the u-joints and gimbal bearing. Also a good time to thoroughly inspect the u-joint bellows.​
