⚠️ Safety & Precautions

• ⚠️ Work on level ground and support your Highlander with jack stands before removing the wheel.
• ⚠️ Never rely on a floor jack alone. A jack can slowly lower or tip.
• ⚠️ Your Highlander is a hybrid. Do not touch orange high-voltage cables or hybrid components during this repair.
• ⚠️ Battery disconnect is not required for outer tie rod end replacement.
• ⚠️ A wheel alignment is required after replacing a tie rod end, even if you count the turns carefully.

📋 Before You Begin

• Park your Highlander on a flat, solid surface.
• Set the parking brake and place wheel chocks behind the rear wheels.
• Loosen the front wheel lug nuts slightly before lifting the vehicle.
• Spray penetrating oil on the tie rod jam nut and outer tie rod stud nut. Let it soak for 5-10 minutes.
• A jam nut is the large nut on the threaded steering rod that locks the 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

• Use a 21mm lug nut socket and 1/2-inch drive breaker bar to loosen the front lug nuts about half a turn.
• Do not remove the lug nuts yet.
• Loosen lugs before lifting.

Step 2: Lift and Support Your Highlander

• Use a floor jack to lift the front of your Highlander at the front center jacking point.
• Place jack stands under the proper front support points.
• Slowly lower the vehicle onto the jack stands.
• Gently shake the vehicle by hand to make sure it is stable before working underneath or near the wheel opening.

Step 3: Remove the Wheel

• Use the 21mm lug nut socket 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: Mark the Tie Rod Position

• Use a paint marker to mark the position of the outer tie rod end against the inner tie rod threads.
• Use a tape measure to measure from the jam nut to the center of the tie rod stud. Write this measurement down.
• This helps keep the alignment close enough to safely drive to an alignment shop.
• Mark it before loosening anything.

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 1/4 turn only. Do not move it far from its original position.
• If it is rusty, apply more penetrating oil and wait a few minutes.

Step 6: Remove the Cotter Pin

• Use needle-nose pliers to straighten and pull the cotter pin out of the tie rod end stud.
• If the cotter pin breaks, use the needle-nose pliers to pull out all remaining pieces.
• Do not reuse the old cotter pin.

Step 7: Remove the Castle Nut

• Use a 17mm socket and ratchet to remove the castle nut from the tie rod end stud.
• If the stud spins, press upward on the tie rod end by hand while loosening the nut with the 17mm socket.

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

• Install the outer tie rod separator tool between the tie rod end and the steering knuckle.
• Tighten the separator tool until the tie rod end pops free.
• If needed, lightly tap the side of the steering knuckle with a hammer while the separator is under tension.
• Do not hammer directly on the threaded stud if you plan to compare the old part.
• A loud pop is normal.

Step 9: Count the Turns and Remove the Old Tie Rod End

• Turn the outer tie rod end counterclockwise by hand to remove it from the inner tie rod.
• Count every full turn as you remove it.
• Write down the number of turns.
• This turn count helps place the new tie rod end close to the old alignment setting.

Step 10: Install the New Tie Rod End

• Apply a light coat of anti-seize compound to the inner tie rod threads.
• Thread the new outer tie rod end onto the inner tie rod by hand.
• Use the exact same number of turns you counted during removal.
• Line it up with your paint mark and measurement as closely as possible.

Step 11: Connect the Tie Rod End to the Steering Knuckle

• Insert the new tie rod end stud into the steering knuckle by hand.
• Install the new castle nut by hand first to avoid cross-threading.
• Use a 17mm socket and torque wrench to tighten the castle nut to Torque to 49 Nm (36 ft-lbs).
• Continue tightening slightly only if needed to line up the cotter pin hole with the castle nut slot.
• Do not loosen the nut to align the cotter pin hole.

Step 12: Install the New Cotter Pin

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

Step 13: Tighten the Jam Nut

• Use a 19mm wrench to hold the tie rod end steady.
• Use a 22mm wrench to tighten the jam nut against the tie rod end.
• Tighten the jam nut securely to Torque to 74 Nm (55 ft-lbs) if your wrench access allows a torque wrench adapter.
• If using regular wrenches only, make it firmly tight without moving the tie rod end position.

Step 14: Reinstall the Wheel

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

Step 15: Lower and Torque the Wheel

• Use the floor jack to slightly lift your Highlander off the jack stands.
• Remove the jack stands.
• Lower the vehicle until the tire just touches the ground.
• Use the 21mm lug nut socket and torque wrench to tighten the lug nuts in a star pattern to Torque to 103 Nm (76 ft-lbs).
• Fully lower the vehicle and remove the floor jack.

✅ After Repair

• Get a professional front-end alignment as soon as possible.
• Avoid highway driving until the alignment is checked.
• Recheck the lug nut torque after 25-50 miles: Torque to 103 Nm (76 ft-lbs).
