🔧 Escape - Front Lower Ball Joint (Control Arm) Replacement

On your Escape the front ball joint is built into the lower control arm, so you replace the entire control arm instead of just pressing out a joint. You’ll do this on each front corner where the ball joint is worn.

Difficulty Level: Intermediate | Estimated Time: 2–3 hours per side

⚠️ Safety & Precautions

• 🛑 Always support the vehicle with jack stands. Never work under a car held only by a jack.
• 🛑 Wear safety glasses when working under the car and when using any hammer.
• 🛑 Chock the rear wheels so the Escape cannot roll while the front is in the air.
• 🛑 Suspension bolts are tight; use proper tools and body position to avoid injury.
• 🛑 Do not pry directly against the brake rotor or rubber brake hose.
• 🛑 After this repair, a professional wheel alignment is strongly recommended.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen front wheel lug nuts

• Use the 21mm socket and 1/2" drive breaker bar to loosen (but not remove) the front wheel lug nuts on the side you’re working on.
• Crack each lug nut loose about one turn while the tire is still on the ground.

Step 2: Raise and support the front of the Escape

• Position the floor jack under the front subframe crossmember (solid metal structure under engine).
• Lift until the front wheel is off the ground.
• Place jack stands under the factory pinch weld points or subframe as specified in the owner’s manual.
• Slowly lower the Escape onto the stands and gently rock the car to make sure it is stable.

Step 3: Remove the front wheel

• Use the 21mm socket and 1/2" drive ratchet to remove the lug nuts completely.
• Remove the wheel and set it aside in a safe place.

Step 4: Inspect the area and mark bolt positions

• Use a shop light to clearly see the lower control arm, ball joint connection at the steering knuckle, and the two rear control arm mounting points at the subframe.
• Use the paint marker to mark the position of the control arm mounting bolts relative to the subframe. This helps keep alignment close
• Spray penetrating oil on the ball joint pinch bolt and the control arm mounting bolts. Let it soak a few minutes.

Step 5: Disconnect front sway bar link from strut (if needed)

• On many Escapes, it’s easier to move the control arm if the sway bar link is free.
• Use an 18mm socket and ratchet to remove the nut holding the sway bar link to the strut, while holding the link stud with a wrench or internal hex if required.
• Move the sway bar link out of the way.

Step 6: Remove the ball joint pinch bolt at the steering knuckle

• Locate the pinch joint where the lower ball joint stud goes into the bottom of the steering knuckle.
• Use a 15mm socket and ratchet to remove the nut from the pinch bolt.
• Use a 15mm socket and breaker bar if the bolt is tight, then slide the bolt out of the knuckle.
• If stuck, gently tap the end of the bolt with a hammer while supporting the knuckle.
• Torque for reassembly later: 70 Nm (52 ft-lbs) on the pinch bolt nut.

Step 7: Separate the ball joint from the steering knuckle

• Insert the ball joint separator fork between the control arm ball joint and the steering knuckle.
• Tap the fork with a hammer until the ball joint pops free from the knuckle.
• If you do not have a fork, you can carefully use a pry bar under the control arm and pry downward while tapping the knuckle ear with a hammer.
• Keep fingers away from pinch points

Step 8: Remove rear control arm mounting bolts

• Locate the two main mounting points of the control arm at the subframe (one large front bushing, one rear bushing).
• Use an 18mm socket and 1/2" drive breaker bar to break loose the bolts.
• Then use an 18mm socket and ratchet to remove both bolts completely while supporting the control arm with your other hand.
• Note any shims or washers and keep them in order.
• Torque for reassembly later: front control arm bolt 135 Nm (100 ft-lbs), rear control arm bolt 135 Nm (100 ft-lbs).

Step 9: Remove the control arm from the vehicle

• With the rear bolts removed and the ball joint free, pull the control arm out toward you.
• You may need to twist and wiggle the arm around the subframe and driveshaft.
• If needed, gently lever with a pry bar to free the front bushing from its seat.

Step 10: Prepare the new control arm

• Compare the new control arm to the old one to ensure shape, mounting points, and ball joint orientation match.
• Use a wire brush to clean the subframe mounting surfaces where the bushings sit.
• Apply a light film of anti-seize compound to the shanks of the mounting bolts (not on the threads if the manufacturer advises dry threads).

Step 11: Install the new control arm into the subframe

• Position the new control arm into the subframe, inserting the front and rear bushing ends into their brackets.
• Insert the new or cleaned mounting bolts by hand to avoid cross-threading.
• Use the 18mm socket and ratchet to snug the bolts but do not fully torque them yet. The final torque should be applied at normal ride height.

Step 12: Insert ball joint stud into steering knuckle

• Use a floor jack under the outer end of the control arm (near the ball joint) and gently raise it to line up the ball joint stud with the knuckle opening.
• Guide the ball joint stud fully into the knuckle.
• Reinstall the ball joint pinch bolt through the knuckle and ball joint slot.
• Install the nut and tighten with a 15mm socket and ratchet.
• Final torque: 70 Nm (52 ft-lbs) with the 3/8" drive torque wrench.

Step 13: Torque control arm bolts at ride height

• Support the Escape with the jack stands but also place the floor jack under the outer ball joint area and raise the control arm until the hub center is close to normal ride height (roughly where it would sit with the wheel installed and on the ground).
• Use an 18mm socket and 1/2" drive torque wrench to torque the front and rear control arm bolts.
• Front control arm bolt: 135 Nm (100 ft-lbs).
• Rear control arm bolt: 135 Nm (100 ft-lbs).
• Tighten slowly and steadily to avoid slipping

Step 14: Reattach the sway bar link

• Reinstall the sway bar link stud into the strut bracket.
• Use an 18mm socket and ratchet to tighten the nut while holding the stud as required.
• Tighten to 75 Nm (55 ft-lbs) with the 3/8" drive torque wrench.

Step 15: Reinstall the wheel

• Put the wheel back on the hub and start all lug nuts by hand.
• Use the 21mm socket and ratchet to snug the lug nuts in a star pattern.

Step 16: Lower the Escape and torque lug nuts

• Use the floor jack to lift the Escape slightly, remove the jack stands, then lower the vehicle fully to the ground.
• Use the 21mm socket and 1/2" drive torque wrench to torque each lug nut in a star pattern.
• Lug nut torque: 135 Nm (100 ft-lbs).

Step 17: Repeat on the other side

• Repeat Steps 1–16 on the other front side if you are replacing both control arms (recommended).

✅ After Repair

• 🚘 Take the Escape for a short, gentle test drive on a smooth road. Listen for any clunks, pops, or unusual noises over bumps and during turns.
• 🎯 Check that the steering wheel is centered and the car does not pull strongly to one side.
• 🔍 After the test drive, visually inspect the control arm bolts, ball joint area, and sway bar links to ensure everything is still tight and seated correctly.
• 📏 Schedule a professional four-wheel alignment as soon as possible to prevent uneven tire wear and to restore proper handling.
