96 transom with gen II alpha one 5.7l

The boat runs great but when turning to the right it sounds like a ujoint knock but nothing when turning left, weird. I pulled the drive for inspection and motor alignment check. The u-joints look new. I plan to replace the gimbal and ujoints regards of what I find. Some told me the drive can hit the housing and cause the same noise. Has any one experienced the same issue.

Is it only on hard lock or is it when you are just off dead centre? Does it do it out of gear or only under load? and is it engine speed dependent? does it change tone or frequency as the engine speed changes?

It's only under hard lock. Everything looks good. I replaced the gimbal and now the ujoints are a pain. I'm missing something. I do not notice anything under normal operation. I'm not sure if its speed dependent. I only turn when going slow because of the knocking.
