🔧 Highlander - Outer Tie Rod End Replacement

This repair replaces a worn outer tie rod end, which connects the steering rack to the front wheel knuckle and helps steer your Highlander. A bad tie rod end can cause looseness, clunking, uneven tire wear, or poor steering feel.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours per side

⚠️ Safety & Precautions

• ⚠️ Support your Highlander with jack stands before working under or near the front suspension.
• ⚠️ Never rely on a floor jack alone. A floor jack lifts the vehicle; jack stands hold it safely.
• ⚠️ Replace tie rod ends in pairs if both sides show wear, but one side can be replaced if only one is damaged.
• ⚠️ A wheel alignment is required after this repair to prevent tire wear and steering pull.
• ⚠️ Do not hammer directly on the steering knuckle threads or tie rod stud threads.
• ⚠️ Battery disconnect is not required for this repair.

📋 Before You Begin

• Park your Highlander on level ground and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Keep the steering wheel centered before lifting the vehicle.
• Spray penetrating oil on the outer tie rod jam nut and the tie rod end stud nut. Let it soak for 5-10 minutes.
• A jam nut is the locknut on the threaded inner tie rod that holds the outer tie rod end in position.
• A cotter pin is a small bent safety pin that keeps the castle nut 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 about half a turn.
• Do this while the tire is still touching the ground so the wheel does not spin.
• Loosen only, do not remove yet.

Step 2: Lift and Support the Front of the Vehicle

• 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 make sure it is stable.

Step 3: Remove the Front Wheel

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

Step 4: Measure and Mark the Tie Rod Position

• Use a wire brush to clean the threads around the jam nut and outer tie rod end.
• Use a paint marker to mark where the jam nut sits on the inner tie rod threads.
• Use a tape measure to measure from the center of the tie rod stud to a fixed point on the inner tie rod.
• Write the measurement down before removing the part.
• This helps keep the alignment close enough to drive carefully to an alignment shop.
• Counting turns also helps.

Step 5: Loosen the Jam Nut

• Use a 22mm wrench on the jam nut.
• Use a 19mm wrench on the tie rod end flats if needed to hold it steady.
• Turn the jam nut loose about one turn only.
• Do not move it far from your paint mark.

Step 6: Remove the Cotter Pin and Castle Nut

• Use needle-nose pliers to straighten and pull the cotter pin out of the tie rod end stud.
• Use a 19mm socket and ratchet handle to remove the castle nut from the stud.
• If the cotter pin is rusty and breaks, use needle-nose pliers to pull out all remaining pieces.

Step 7: Separate the Tie Rod End from the Steering Knuckle

• Install the outer tie rod end puller over the tie rod end and steering knuckle.
• A tie rod end puller is a small press tool that safely pushes the stud out of the tapered hole.
• Use a ratchet handle or the correct wrench supplied with the puller to tighten the tool until the stud pops loose.
• Do not use a pickle fork unless you are replacing the tie rod end, because it can damage the rubber boot.

Step 8: Unscrew the Old Outer Tie Rod End

• Turn the outer tie rod end counterclockwise by hand to remove it from the inner tie rod.
• Count the exact number of turns it takes to remove it.
• Use a 19mm wrench if it is tight.
• Keep the jam nut near your paint mark.

Step 9: 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 mark and measurement as closely as possible.
• Use a 19mm wrench only if needed, but do not force the threads.

Step 10: Connect the Tie Rod End to the Steering Knuckle

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

Step 11: Install the New Cotter Pin

• Slide the new cotter pin through the castle nut and tie rod stud hole.
• Use needle-nose pliers to bend the cotter pin ends around the nut.
• Make sure the cotter pin cannot fall out.

Step 12: Tighten the Jam Nut

• Hold the tie rod end steady with a 19mm wrench.
• Use a 22mm wrench to tighten the jam nut against the new tie rod end.
• Tighten it firmly while keeping the tie rod end straight.
• Torque to 74 Nm (55 ft-lbs) if using a suitable torque wrench adapter.

Step 13: Reinstall the Wheel

• Put the wheel back onto the hub.
• Install the lug nuts by hand first.
• Use a 21mm lug nut socket and ratchet handle to snug the lug nuts in a star pattern.

Step 14: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack rated 3-ton minimum to slightly lift the vehicle off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower your Highlander until the tire touches 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 to make sure there is no binding or clunking.
• Drive slowly at first and make sure the steering wheel returns normally.
• If the steering wheel is off-center or the vehicle pulls, stop driving except to go directly to an alignment shop.
• Get a professional front wheel alignment as soon as possible after replacing the tie rod end.
• After 25-50 miles, recheck the lug nut torque with a 21mm lug nut socket and 1/2-inch drive torque wrench: Torque to 103 Nm (76 ft-lbs).
