Greetings,
I am replacing my ball joints on my 1988 F150 4x4. My manual does not give any torque specs for the nuts, could someone please tell me what they are?
Thanks much!
This is a fairly critical procedure found in Ford factory service manuals that you must follow to ensure proper ball joint "preload" and good steering return. If not done correctly the ball joints may wear prematurely.
1. Torque lower nut to 40 ft-lbs.
2. Torque upper nut to 85-100 ft-lbs. If you cannot install the cotter pin, continue tightening to align the nearest hole in the stud with the castellation in the nut.
3. Final torque the lower nut to 95-110 ft-lbs.
