SE North Dakota | Last week posted about vibration in truck at 68 mph. This is what all have been done
1. All new u joints in both front and back driveshaft. Also spun balanced them twice.
2. New front differential.
3. Air suspension set to right ride height.
4. New tires and balanced tires.
5. Removed axles and now have been just running the truck in the shop. Vibration still there with axles removed.
6. Removed rear drive shaft. Vibration still there.
7. Removed front drive shaft vibration gone.
8. So now with vibration gone wouldn't you think it's either in that front driveshaft or that front diff?? Had driveshaft rebalanced. Vibration seems worse now. Guy that did driveshaft says it's true and issues in that front differential so replaced that. Vibration still there so now I am fed up and took it to him and now he says injectors are bad?? Wtf.

Thanks. | |
