04 driveshaft squeak?

[jerryelo]

Have an 04 fx4 levii which has a weird squeaking noise coming from what I believe is the driveshaft slip yoke. 40,000 miles. The squeak happens during light acceleration and quits at about 15 to 20 mph. During harder accel no noise at all and when I let up during light accel the squeak stops. I am debating about getting re-greasing the slip yoke but was wondering if anyone has had this problem.

I believe my friend had a similar squeaking problem on the exact same year and model truck. If I'm not mistaken it was the bolts for the bed.

I would check the U-joints on the drive line.
