pulley squeek ?
I have an '05 f350 sd 4x2 with the v10. i have 4300 miles on it and a few weeks ago i noticed a high pitched squeek coming from the belt, so i used belt dressing on it and it went away, but 2 days ago it came back, no amount of belt dressing is making it go away this time. I think i have narrowed it down to the tensioner on the lower right of the belt assembly. I heard the bearings go quickly on this setup. still under warranty so have an appointment next week at the stealership, but anyone else with this problem?

Belts can need replacement as early as you rs. First, I hate belt dressing. Temporarilly it helps but it just makes things worse in the long run. I find this to be most true with serpentine belts. V belts appear to be less prone to belt dressing problems.
With a serpentine, the better fix is to thoroughly clean the belt to remove the gummy residue of the dressing. I use a rag with rubbing alcohol and wipe until the belt is clean. The belt has to be off to do this properly. Next I clean all the pulley surfaces so there is no residue. Then I rough up the shiney/smooth pully surfaces with some coarse sand paper. THis usually fixes the problem unless the belt itself is glazed, ie has a shiney smooth appearance. If the belt is glazed I use a new one and toss the old one in the trunk as a "road emergcency" spare.
If it is a pulley, sometimes you can find a replacement bearing. Bearings are easy to replace if you have a puller, they are relatively cheap. If you can't find a proper bearing, you may have to spring for the entire pulley assembly(seems Ford doesn't like to sell components) and this can get expensive, upwards of $100.
Good Luck,
