Vibration Help

Wert · #1 (**permalink**) 02-22-2011, 08:59 PM

I am new to the powerstroke world and have a vibration that I cant quite identify. Vibration happens during light acceleration after the truck has shifted and is lower in the RPM range, most consistently between 40 & 45 MPH. It feels like it comes from more towards the rear but I cant be sure. It doesn't happen during heavy acceleration.

I examined my driveline u-joints and everything felt good. The Driveshaft carrier bearing was loose in the mount so I replaced it, but this did not fix the problem.

Any advice would be much appreciated.

I have similiar issue, only to find out there is ice stuck on the wheel. I had to break it off. No more vibration, I am not sure about yours. We got tons of snow up here and the weather right now is brutal (-8 degrees).

Nothing to due with Ice... I have had the vibration since I bought the truck last Sept.

Try LOCKING the front hub IN, manually and see if the noise stops....

If not, pull the front driveshaft out to check the Cardan Joint ball&spring, even if the U-Joints are good, that can cause you problems.

Problem persists even with the hubs locked in, I will have to check the Cardan Joint when I get some free time... Until then any other ideas?
