A swing and a miss on this one... The centering yoke came in last night's Amazon delivery, including the driver tripping and falling on the porch in front of the Ring camera. Everything matched except the center post diameter was wrong. I thought I checked that, but the new is 1/2" and the old is 5/8", so must be I didn't.
The center pin in question.
I tried the two driveshaft shops in town today and no parts... I could order a new centering ball for $100 from one, but I wasn't confident that it would be correct... and $100 for this centering ball is a bit ridiculous. T
So, keeping with my track record of learning some things the hard way... I left the driveshaft at the better (of the two) driveshaft shop and they are going to weld on a new double cardan joint and I'll be done. That will take care of any balance or phasing issues at the same time.
Yep, should have done that in the first place and I'd be done with this.
