I recently took my 03 F250 6.0 to the dealership to have the slip joint lubricated. When I got it back it had developed a loud hum and vibration beginning about 40 and gets progressively worse up to about 52mph. Took it up to 60 turned the key off and bumped into neutral. Still had the hum and vibration as the truck decelerated until it dropped below 40. Took it back to the dealer and they reported that the drive shaft was 180 out. Called and said it was fixed. Drove off the lot and there was no difference. This was not happening before I took it in for slip joint lube. Had the xmission checked, no problem. Had the driveshaft balanced, no difference. Carrier bearing was good. Had the tires checked for belt separation and wheels balanced. No change. Changed both u joints, no change..I am about out of options short of putting a bullet into the damn thing. Could this be shocks, motor mounts, bent wheel? I sure don't want to take it back to the dealership so that they can throw parts at the thing until they find one that works and charge me for all of them...IF they can find a solution in the first place.
