⚠️ Safety & Precautions

• ⚠️ Always support your Highlander with jack stands before working underneath or near a wheel.
• ⚠️ Do not rely on a floor jack alone. A floor jack lifts the vehicle; jack stands safely hold it up.
• ⚠️ Wear safety glasses and gloves. Rust and dirt can fall when loosening steering parts.
• ⚠️ Count the turns when removing the old tie rod end. This helps keep the alignment close enough to drive to an alignment shop.
• ⚠️ A professional wheel alignment is required after this repair to prevent tire wear and steering pull.
• ⚠️ Battery disconnect is not required for this repair.

📋 Before You Begin

• Park your Highlander on level ground.
• Set the parking brake.
• Place wheel chocks behind the rear wheels.
• Straighten the steering wheel before lifting the vehicle.
• Spray penetrating oil on the tie rod jam nut and tie rod end stud nut. Let it soak for 5-10 minutes.
• A jam nut is the lock nut on the inner tie rod that holds the outer tie rod end in place.
• A castle nut is a slotted nut that uses a cotter pin to keep it from loosening.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Lug Nuts

• Use a 21mm lug nut socket and 1/2-inch drive breaker bar to loosen the lug nuts on the side you are repairing.
• Only loosen them about 1/2 turn while the tire is still on the ground.
• Loose first, lift second.

Step 2: Raise and Support the Front of the Highlander

• Use a floor jack rated 3-ton minimum to lift the front of your Highlander at the front center jacking point.
• Place jack stands rated 3-ton minimum under the approved front support points.
• Slowly lower the vehicle onto the jack stands.
• Gently shake the vehicle by hand to confirm it is stable before removing the wheel.

Step 3: Remove the Front Wheel

• Use a 21mm lug nut socket to remove the loosened lug nuts.
• Remove the wheel and set it flat under the vehicle as an extra safety backup.

Step 4: Mark and Measure the Tie Rod Position

• Use a paint marker to mark the exposed threads where the outer tie rod end meets the jam nut.
• Use a tape measure to measure from the center of the tie rod end stud to a fixed point on the inner tie rod.
• Write down the measurement.
• This helps keep the steering close enough for a short drive to the alignment shop.
• Alignment is still required.

Step 5: Loosen the Jam Nut

• Hold the outer tie rod end with a 19mm wrench if needed.
• Use a 22mm wrench to loosen the jam nut by turning it slightly away from the outer tie rod end.
• Do not spin the jam nut far down the threads. Just break it loose.

Step 6: Remove the Cotter Pin

• Use needle-nose pliers to straighten and pull out the cotter pin from the tie rod end stud.
• If the cotter pin is rusty, use the needle-nose pliers to work it back and forth until it comes out.
• Discard the old cotter pin. Do not reuse it.

Step 7: Remove the Castle Nut

• Use a 19mm socket and 3/8-inch drive ratchet to remove the castle nut from the tie rod end stud.
• If the stud spins, press down on the tie rod end by hand while loosening the nut with the 19mm socket.

Step 8: Separate the Tie Rod End from the Steering Knuckle

• Install the tie rod end puller over the tie rod end stud and steering knuckle.
• Tighten the puller with the correct wrench from your puller kit until the stud pops free.
• If using a ball joint separator fork, place it between the tie rod end and knuckle, then tap it with a hammer 16 oz.
• The separator fork may damage the old boot, which is acceptable because the tie rod end is being replaced.
• The pop sound is normal.

Step 9: Remove the Old Outer Tie Rod End

• Use your hand to unscrew the outer tie rod end from the inner tie rod.
• Count the exact number of turns it takes to remove it.
• Write down the turn count.
• Keep the jam nut in the same position as much as possible.

Step 10: Install the New Outer Tie Rod End

• Thread the new outer tie rod end onto the inner tie rod by hand.
• Use the same number of turns you counted during removal.
• Line it up with your paint marker mark and measurement from the tape measure.
• Make sure the tie rod end points downward into the steering knuckle hole.

Step 11: Seat the Tie Rod End Stud

• Insert the new tie rod end stud into the steering knuckle.
• Install the castle nut by hand first to avoid cross-threading.
• Use a 19mm socket and 1/2-inch drive torque wrench to tighten the nut.
• Torque to 49 Nm (36 ft-lbs).
• If the cotter pin hole does not line up, tighten the nut slightly more until the hole lines up. Do not loosen the nut to align the hole.

Step 12: Install the New Cotter Pin

• Slide the new cotter pin through the hole in the tie rod end stud.
• Use needle-nose pliers to bend the cotter pin ends around the castle nut.
• This locks the nut in place.

Step 13: Tighten the Jam Nut

• Use a 19mm wrench to hold the new outer tie rod end steady.
• Use a 22mm wrench to tighten the jam nut against the new tie rod end.
• Torque to 74 Nm (55 ft-lbs).
• If using hand wrenches only, tighten it firmly without twisting the inner tie rod boot.

Step 14: Reinstall the Wheel

• Place the wheel back onto the hub.
• Thread the lug nuts by hand first.
• Use a 21mm lug nut socket and 3/8-inch drive ratchet to snug the lug nuts in a star pattern.

Step 15: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack rated 3-ton minimum to lift the vehicle slightly off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower your Highlander to the ground.
• Use a 21mm lug nut socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Torque to 103 Nm (76 ft-lbs).

✅ After Repair

• ✅ Turn the steering wheel left and right while parked. Listen for binding, popping, or scraping.
• ✅ Take a slow test drive around the block. Keep speed low if the steering wheel is off-center.
• ✅ Get a professional wheel alignment as soon as possible.
• ✅ After 25-50 miles, recheck the wheel lug nut torque with a 21mm lug nut socket and 1/2-inch drive torque wrench.
• ✅ If your Highlander pulls hard, the steering wheel is crooked, or the tires squeal, do not keep driving except to reach an alignment shop safely.
