Slight vibration in turns

[Schouty]

Hey, so I finally got my drive back on and took my boat for a test drive. And I still have a vibration in turns. It has new u joints and I checked the engine alignment and it's good. As soon as I straighten out it stops. I'm going to try another prop just to eliminate it. I also hear a light groan when it's turning. The boat it's a 16 Donzi with a 350 and a volvo 280. Any help would be great, thanks.

Did you replace the PDS bearing when you did the crosses?

Yes, I replaced the bearings last year. I have the Borg and Warner extension box with the two bearings.

Although I doubt that it would contribute to your vibration, the engine alignment involves using the triangulation procedure.
Is that how you checked this?

I realize that you replaced these..... but from what you describe, this is symptomatic of PDS bearing failure.
