Question about Ford Freestar
My problem is this. I have been getting vibration and hesitation like it looses power momentarily with a ****/bump/clunk ate the end of the hesitation while driving. The vibration and hesitation do not always happen simultaneously. This happens at speeds above 45 MPH. The vehicle seem to shift normally and does not have any knocking or engine noise. I was thinking Drive/half shaft or related issues but am no mechanic. What could this be?
Check the drive shaft "U" joints and slip joint for bad wear . If you have a centre bearing check it for serviceability. pull the plug in the diff and check the magnet for metal bits.

Move it to 3rd instead of drive and see if you still have the noise. May be transmission related since you have replaced everything else.

SOURCE: Clunk/rattle noise and vibration
Could be a loose exhaust hanger or a suspension issue. You will need to raise the vehicle up on a rack and visually inspect the truck for the problem. Start by using your fist or a rubber mallet to bang on the exhaust system and suspension to see if you can simulate the noise and identify the problem. Definently inspect it or have it inspected because if something is broken/loose it could come apart on you while you are driving.

I would check the driveshaft universal joints and the play in the yolk joints where the driveshaft exits the transmission and where it enters the differential.
It could be the preliminary vibration caused by the deterioration in a universal joint, forewarning you that it's on the way out. Good Luck Vern

Testimonial: "Your answer was right-on. I took my truck to the shop the next day, and it is driving perfectly."
If its 2wd, there are no driveshafts. check the sway bar links/ and bushings,
