Wheel Studs

This procedure covers the removal and replacement of wheel studs on the rear axle of a 2015-2020 Ford F-150 with 5.0L V8 Coyote engine.

Tools required

Parts

• Wheel stud(s) × 1 — Ford M-1107-A or OEM equivalent

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Loosen lug nuts on the wheel with the damaged stud(s) while vehicle is on the ground
3. Raise rear of vehicle with floor jack at designated jacking points
4. Support vehicle securely on jack stands rated for vehicle weight
5. Remove wheel completely and set aside

Procedure

1. 1

   Access the damaged wheel stud
   Inspect the hub and identify the damaged or broken wheel stud. Rotate the brake rotor/hub assembly as needed to position the damaged stud for easiest access. On some positions, you may need to rotate the hub to clear brake caliper or suspension components.
2. 2

   Remove the damaged wheel stud
   Use a ball peen hammer or brass hammer to drive the damaged stud out from the front (wheel side) of the hub. Strike the stud firmly at the threaded end to force it through the hub bore. The stud should push out toward the brake side of the hub. If the stud is severely damaged or corroded, you may need to use a chisel to break it free.
   ⚠Avoid striking the hub face or brake rotor. Use controlled hammer strikes on the stud only.
3. 3

   Clean the hub bore
   Once the old stud is removed, use a wire brush to clean the stud bore in the hub. Remove any rust, corrosion, or debris from the hole to ensure the new stud seats properly. Inspect the bore for damage or cracks.
4. 4

   Install the new wheel stud
   Insert the new wheel stud into the hub bore from the back side (brake side). The stud should slide through with the serrated shoulder facing outward. Push the stud in by hand as far as it will go. Apply a small amount of anti-seize to the serrated shoulder if desired, but keep it away from the wheel mounting face.
5. 5

   Seat the wheel stud
   Use a wheel stud installer tool or create a makeshift installer using a stack of washers and a deep socket that clears the stud threads. Thread a lug nut onto the stud backward (flat side out), place washers and socket over the stud, then tighten the lug nut. This will pull the stud through the hub until the serrated shoulder seats firmly against the back of the hub. You should feel solid resistance when fully seated.
   ⚠Do not over-tighten during installation. Stop when the stud shoulder is fully seated to avoid damaging the hub or stripping the stud.
6. 6

   Verify stud installation
   Remove the installation tool, washers, and lug nut. Inspect the stud to confirm it is fully seated with the serrated shoulder flush against the hub. The stud should not move or rotate when pulled by hand. Verify that sufficient thread length extends beyond the hub for proper lug nut engagement.
7. 7

   Reinstall the wheel
   Clean the hub mounting surface and wheel mounting surface with a wire brush. Position the wheel onto the hub, aligning all lug holes. Thread all lug nuts onto studs by hand, including the newly installed stud. Tighten lug nuts in a star pattern to ensure even seating.
   ℹ️Hand-tighten all lug nuts before using any tools to ensure wheel is properly centered on hub.

   Wheel Lug Nuts140 Nm (103 lb-ft)
8. 8

   Lower vehicle and perform final torque
   Carefully remove jack stands and lower the vehicle to the ground. With the vehicle weight on the wheel, torque all lug nuts to specification using a star pattern. Start at 50% of final torque, then go to 100% in a second pass to ensure even clamping force.

Reassembly

1. Ensure all lug nuts are torqued to specification in a proper star pattern
2. Verify wheel is secure with no wobble or looseness
3. Store damaged stud as a reference if ordering additional replacements

Verification

• Test drive vehicle at low speed and verify no vibration or unusual noises from the wheel
• Re-torque lug nuts after 50-100 miles of driving to confirm proper retention
• Visually inspect the new stud after test drive to ensure it remains properly seated
