Replace Cam gear, Thrust plunger, and spring.
Bet your "bearing knock" goes away.
Went through this on my '28 Coupe last summer. Replaced the ancient & failed Fibre gear with an aluminum cam gear, plunger, and spring from Bratton's. No more "bearing knock".
Also no excessive noise from metal cam gear.
