Hello all.
Finally have Shaun (the 2001 Dodge Ram) on the road. I replaced the U-joints and centre support bearing (CCB) because there was a bit of vibration at highway speeds. Also the CCB rubber was loose. Upon inspection, the U-Joints were brinneled on the load side of the bearing surface... 135K, and with a 5th wheel, who knows what loads they were put under. Figured it was time to swap them out.
Not the first time with U-joints by a long shot, and I was careful to make sure all the yokes went back together the way they came apart; orientation is the same.
BUT...
At around 70 mph+, there still is a harmonic vibration that gets worse as speed increases...
The splines from the front section do not have a master spline, not to mention getting the damn thing back together again was a real PITA. I am wondering if I have somehow indexed the two shafts incorrectly. Does anyone have any info on this? The Factory manual is pretty lame on info... Thanks... JK
