Noise after using 4 wheel drive
I just bought my first Ford truck and am the first one in a family of Chevy owners to do so. I could not be more happy with the truck with one exception.
After I engage the four wheel drive I get a soft squeaky/clicky noise with each rotation of the tire. If I put the truck back in 2wd and drive it for a mile or so the noise will go away. If I put the truck back into 4X4 the problem comes back. The truck only has 35k miles. I would greatly appreciate any help.
Thanks.
Joe

Not likely, the drive shaft is going to spin about 4 times for every full rotation of the tires.
I think it may be a lack of lubrication. Try running it in 4wd for a few minutes to get the parts moving and oil to everything. If the noise doesn't go away, feel the hubs for heat.

You have ESOF with the **** on the dash?
With the truck in 2WD, reach around the back of the front wheels, and spin the u-joint with your hand. It should be somewhat hard to move, but once moving, should be smooth and not ratchety or gritty.
The noise you hear might be the needle bearings (inner spindle bearing) where the axle rides inside the wheel bearing. They are NOT spinning in relation to the axle when in 4WD. When you go back to 2WD, they might be dry and make noise for a period of time.
This WILL get worse, and cost big $'s to fix if not taken care of right away.
If you spin the u-joint behind the wheel and it IS gritty or ratchety, LOCK THE HUBS MANUALLY until you get it fixed (you will notice a mild thumping when making tight turns but it's not a big deal).

If they move smoothly, and not gritty or ratchety (or not at all if they are bad enough), they are OK.
