Recently I have noticed a thumping noise I believe coming from the front drivers side the most noticeable between 30 to 40 mph. This is in 2WD or 4WD. It resembles the sound of a flat spot on a tire; yet all the wheel weights are in place. I have not noticed any vibration or steering issues; just the noise that seems to go away around 40mph. Please advise.
Do you
have the same problem?

Check the tires for shifted belts. Also, make sure the tire is balanced. Even though the weights appear to be fine, you may have lost one.

Finally, does the sound change when you make turns?

Let me know.

The tires look fine; I don't see any belts shifted. I can't tell if I am missing any wheel weights. Turning does not affect the noise. I just road around with a mechanic from the local Ford dealership( where I bought the truck new) so he could hear what I was refering to. He could definately hear it at 30mph but couldn't tell exactly where it was coming from. I am leaving it with them tomorrow(Wed. 13th) so they can find it. I'll let you know what they say.

I just got the diagnosis from the dealer mechanic about my low speed thumping noise. As you had suspected; it was a front tire wearing ununiformly causing the thumping. He recommended a tire rotation which put the problem tire at the rear. He said that initially there will still be some noise but will eventually go away as the tire wears down. Thanks for your response; I think your diagnosis was right on the money; especially not being able to see the vehicle and just going off my description of the problem!
