My 55 series 2 long wheelbase (3200) has a two piece driveshaft and lots of vibration!
After new u joints and a new center support with bearing there is still plenty of vibration. Driveshaft u joints are phased correctly. Truck is stock with only 76,000 miles. 235ci motor with 4 speed. Tires are new and balanced.
Friends have suggested that I go to a one piece driveshaft to get rid of vibes.
Has anyone done this? Is this a recommended cure for the vibration?
Thanks!
