Symptoms
A clunk from the front end, or nothing at all: a missing or loose upper ball-joint nut or lower control-arm bolt may give no warning before the arm separates.
The fix, step by step
- Four campaigns cover this (24V-770, 25V-260, 25V-310 and 25V-308).
- For 25V-260 and 25V-308, Ford told owners not to drive the truck until it was repaired.
- The remedy is to inspect and, if needed, tighten or replace the fasteners, ball joint and knuckle.
- On any lifted or modified truck, check the torque on the upper ball-joint nuts and the lower control-arm pivot bolts after installation and again after the first trail run.
Tools & part numbers
- Torque wrench
