Hi all, not sure if this is in the right place. If not please relocate... I have a Farmall BN that runs and drives great except... When I let out the clutch the left side seems like it jumps around... Almost as if there's a u-joint with bad bearings in there, but I took off the couple caps I could on the left drive and found this bolt a little bit loose. Not sure if that would cause it, but does anybody know the torque for the bolt in the picture or have any other ideas on why the left side of the tractor bounces around on takeoff?
