slip yoke problem / TF 727

The seal isn't leaking it's just enough play it's the only place I can see a vibration coming from. I measured outside diameter 1.68 . Driveshaft Specialist of Texas built the shaft used a SONNAX yoke for trans end . Hard for me to measure vertical play but close as I can get is around .06 of play. Pinion angles are only 2 degree difference.
