Hello and thanks for using Just Answer.

This knocking sound is most like coming from two places, the ujoints on the front driveshaft or the stabilizer bar links. Let me know if this may be the case.

There is an actual Ford Technical Service Bulletin related to this issue. See below.

ISSUE

Some 1998-2004 F-150 4X4 vehicles with a one piece drive shaft may exhibit a clunking or grunting noise and/or a shudder sensation from the driveline. The condition will typically occur during light to moderate acceleration from a stop and/or braking.

SERVICE PROCEDURE

  1. Road test the vehicle to verify the condition.
  2. Remove the driveshaft per Section 205-01 of the Workshop Manual.

    NOTE: INDEX (MARK) THE DRIVESHAFT YOKE TO AXLE FLANGE FOR REASSEMBLY.

  4. Re-index and reinstall the driveshaft per Workshop Manual.
  5. Check the transfer case fluid level and add MERCON Automatic Transmission Fluid XT-2-QDX if necessary.
  6. Road test to verify the condition is corrected.
