1959 Fiat 1200 TV Driveshaft Vibration

Hi All
I seem to be having a problem with driveshaft vibrating when I shift into 3rd or 4th gear. I am on my third flexjoint. It seems from the vibration it is eating up the rubber. Any suggestions? Thrust bushing? Mis alignment?
Thank you

I’d probably suggest finding a specialist who can balance it for you, they could also check it is true as well, a very slight bend can cause a very significant imbalance once you get the speed up
