Vibration

[DIESEL FOOL]

Any guys with a stock truck or lift installed having trouble with driveline vibration, have the shop check the rear differential flange for side to side runout. Acceptable is .005" but mine was .060" and had to be replaced. My flange was never touched from the factory, just a shitty part.

Intakes fault for sure

Nope, I only have an S&B, not one of those high powered AFE intakes.

ive got the vibration at 80 mph+ and only with my boat behind me, and my vibration is VERY evident.

If your boat is heavy, then it is most likely the steady bearing. I have a heavy toyhauler and the steady bearing rattled which is why I put in a one piece driveshaft. then discovered the bad flange on the differential. The driveline guys say it is quite common.
