So after taking apart the torque tube on my 51 3100, to try and address a leak at the slide on the torque tube, the speedometer not working ,a leak on the bottom of the rear bearing retainer and a leaking PTO cover the truck has developed a vibration after I put it all back together. It only seems to be under load at higher rpms in fourth gear. Prior to taking it apart it ran and drove perfectly fine. I took it back apart and everything looks to be in good condition. When I took it apart the first time I did see the trunnion was in backward. I'm basing that on the slots in the trunnion were facing to the rear of the truck in stead of the front. Am I correct that the slots should be to the front to better pick up lubrication from the transmission? The only part that I was not sure of after taking it apart the first was the position of the rear trunnion bearing and bushing. I disassembled the trunnion from the front yoke and reinstalled it correctly facing the slots towards the front. My question is which picture with trunnion bushings installed Is correct picture #1 or picture #2. When I reassembled it I did it as in picture #1. Seemed to move around alot and only stay center by the torque tube ball. Thanks for any help.
