🔧 Focus - Outer Tie Rod End Replacement

The outer tie rod end connects your steering rack to the front knuckle. Replacing it restores tight steering and helps prevent uneven tire wear, but you’ll need a wheel alignment afterward.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours (one side)

⚠️ Safety & Precautions

• ⚠️ Support your Focus on jack stands before working underneath.
• ⚠️ Keep the steering wheel centered and the key off so the wheel doesn’t turn while parts are loose.
• ⚠️ Do not reuse a damaged self-locking nut or cotter pin (if equipped).
• ⚠️ Plan for an alignment after replacement to avoid tire wear and wandering.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the wheel lug nuts

• Use a 19mm socket with a breaker bar to loosen the front wheel lug nuts 1/2 turn (do not remove yet).

Step 2: Raise and support the front corner

• Lift the front corner with a floor jack at the proper jack point.
• Set the car onto jack stands and gently shake the car to confirm it’s stable.
• Remove the wheel using the 19mm socket.

Step 3: Mark and measure for a close “starter” alignment

• Use a paint marker to mark the position of the jam nut on the threaded inner tie rod.
• Use a tape measure to measure from the center of the tie rod end stud to a fixed point on the inner tie rod (or count turns in Step 6). Write it down.
• This helps you drive to the alignment shop.

Step 4: Loosen the jam nut

• The jam nut is the nut that “locks” the tie rod end position on the threads.
• Hold the tie rod end body with an adjustable wrench (10-inch).
• Use a 21mm open-end wrench to crack the jam nut loose (only loosen it, don’t move it far).

Step 5: Remove the tie rod end nut from the knuckle

• If your tie rod end uses a cotter pin, straighten and remove it using needle-nose pliers and diagonal cutters.
• Use an 18mm socket to remove the tie rod end nut.

Step 6: Separate the tie rod end from the knuckle

• Install a tie rod end puller (specialty) and tighten it until the stud pops free.
• Don’t hammer the threaded stud.

Step 7: Remove the old tie rod end (count turns)

• Spin the tie rod end off the threads by hand and count the exact number of turns it takes to come off.
• Use a wire brush to clean the exposed threads on the inner tie rod.

Step 8: Install the new tie rod end

• Apply a light coat of anti-seize compound to the inner tie rod threads.
• Thread the new tie rod end on by hand the same number of turns you counted in Step 7.
• Line up the stud with the knuckle and push it fully into the tapered hole.

Step 9: Tighten the tie rod end nut and secure it

• Install the new nut and tighten using an 18mm socket.
• Torque to 35 Nm (26 ft-lbs) + 90°
• If equipped with a castellated nut: continue tightening only as needed to align the slot, then install a new cotter pin using needle-nose pliers.

Step 10: Tighten the jam nut

• Hold the tie rod end body with an adjustable wrench (10-inch).
• Tighten the jam nut using a 21mm open-end wrench.
• Torque to 55 Nm (41 ft-lbs)

Step 11: Reinstall the wheel

• Reinstall the wheel and hand-thread the lug nuts.
• Lower the car off the jack stands using the floor jack.
• Torque lug nuts in a star pattern using a torque wrench: Torque to 135 Nm (100 ft-lbs)

✅ After Repair

• Start the car and turn the steering wheel lock-to-lock while parked to confirm nothing binds or clunks.
• Road test at low speed first. Steering should feel smooth and centered.
• Get a front wheel alignment as soon as possible (recommended the same day).
• Recheck the lug nut torque after 25–50 miles using a torque wrench.
