So yesterday I was going to work, hit a bump, compressed the front suspension pretty good and I got a vibration. I can feel it on the floor, the steering wheel, the brakes, and the gas pedal. I get it in 2wd, switch to 4wd and it changes how it feels. I removed the front driveshaft and it is gone completely. The U-joints all feel good, could it be my transfer case? With the front driveshaft removed, I stopped, engaged 4wd and it still didn't make any vibrations? One thing skyjacker doesn't do that I read other kits do is re-clock the driveshaft.

Has anyone had issues like this? Why would this start now and not earlier?

I am going to replace 1 u-joint because though it feels good, it is a little tight, maybe it is applying enough force to produce a vibration.

 

Turned out to be the IWE, just happen to fail around the same time as everything else. I am at 37,000 miles, going to the dealer on Monday to see if they will fix this as well as inspect the hubs since I am sure they are toast, even in 4x4 now it continues to make the noise.

 

Sorry to hear your having problems Gerg, but whats the IWE?

 

yea whats iwe?

 

Integrated Wheel End, search...

 

The cause was from a solenoid that actuates the IWE. The solenoid has failed not allowing vacuum to disengage the hubs. There is a TSB out for 2004-2006, this is what I am asking Ford to fix, along with checking out the IWE's to ensure they were not damaged.
