So I am chasing another vibration

2003 KR SD 6.0 early build

156 Inch wheel base

VIN
1FTNW21P93EB53110

225,xxx

Replaced ball joints last fall, replaced wheel bearing (Timken) had rotated tires last week when I did the bearing so I went after the obvious thinking the tires were causing the vibration, put the tires back to the original position, still vibration.

The vibration is at different speeds during acceleration and deceleration, while towing 5th wheeler or not towing.......

Since carrier bearing and 2 of the u joints appear OE, I am going to replace the bearing and u joints.......want to use Dana/Spicer.

So I am trying to save a headache and get the right ones avoiding down time I am not coming up with the correct part number.....for my truck.

 

I may have located a Tech line for Dana Spicer, 877-777-5360, option 1, option 1, 8-5 EST.

I will be contacting them tomorrow.
