⚠️ Safety & Precautions

• ⚠️ Support your Tucson with jack stands before working under or near the vehicle. Never rely on a jack alone.
• ⚠️ Replace tie rod ends in pairs if both sides show wear, but one side can be replaced if only one is loose or damaged.
• ⚠️ The vehicle will need a front wheel alignment after this repair, even if you count the turns carefully.
• ⚠️ Do not hammer directly on the steering knuckle threads or the tie rod stud.
• ⚠️ Battery disconnect is not required for this repair.

📋 Before You Begin

• 🚗 Park your Tucson on level ground with the steering wheel straight.
• 🅿️ Shift to Park and set the parking brake.
• 🧱 Place wheel chocks behind the rear wheels.
• 📏 Measure from a fixed point on the inner tie rod to the center of the outer tie rod stud before removal. This helps keep the alignment close enough to drive to the alignment shop.
• 🖊️ Mark the current tie rod position with a paint marker before loosening anything.
• 🔎 A castle nut is a slotted nut that uses a cotter pin to lock it in place.
• 🔎 A tie rod end puller is a small press tool that separates the tapered tie rod stud from the steering knuckle without damaging the rubber boot.

🔨 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 front wheel lug nuts 1/2 turn while the tire is still on the ground.
• Do not remove the lug nuts yet.
• Loosen before lifting the vehicle.

Step 2: Raise and Support the Front of the Vehicle

• Use a floor jack to lift the front of your Tucson at the front center jacking point or the correct side pinch weld area.
• Place jack stands under the front side support points.
• Lower the vehicle gently onto the jack stands.
• Use your hands to lightly shake the vehicle to confirm it is stable.

Step 3: Remove the Front Wheel

• Use the 21mm lug nut socket and ratchet handle to remove the 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 wire brush to clean the threads where the outer tie rod end meets the inner tie rod.
• Use a paint marker to mark the jam nut position on the inner tie rod threads.
• Use a tape measure to measure from the jam nut to the center of the tie rod stud.
• Write the measurement down before removing the part.
• This keeps steering close, not perfect.

Step 5: Loosen the Jam Nut

• Spray the jam nut and tie rod threads with penetrating oil.
• Use a 19mm wrench on the jam nut.
• Use a 17mm wrench on the inner tie rod flats if needed to keep the inner tie rod from twisting.
• Loosen the jam nut about 1/4 turn only. Do not spin it far from your paint mark.
• The jam nut locks the outer tie rod end in place on the threaded inner tie rod.

Step 6: Remove the Cotter Pin and Castle Nut

• Use needle-nose pliers to straighten and pull out the cotter pin from the outer tie rod stud.
• Use a 19mm socket and ratchet handle to remove the castle nut from the tie rod stud.
• If the stud spins, press upward on the tie rod end by hand while loosening the nut with the 19mm socket.

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

• Install the tie rod end puller over the steering knuckle and tie rod stud.
• Tighten the puller screw with the correct wrench from the puller kit until the tie rod stud pops loose.
• Remove the outer tie rod stud from the steering knuckle.
• A sharp pop is normal.

Step 8: Unscrew the Old Outer Tie Rod End

• Use your hand to spin the old outer tie rod end counterclockwise off the inner tie rod.
• Count the exact number of turns as you remove it.
• Write down the number of turns.
• Do not move the jam nut from the paint mark.

Step 9: Install the New Outer 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 using the same number of turns counted during removal.
• Line it up with your original paint mark and measurement.
• Do not tighten the jam nut yet.

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

• Insert the new tie rod stud into the steering knuckle by hand.
• Install the new castle nut by hand first to avoid cross-threading.
• Use a 19mm socket and torque wrench to tighten the castle nut to Torque to 34-44 Nm (25-33 ft-lbs).
• If the cotter pin hole does not line up, tighten the castle nut slightly more until the slot lines up. Do not loosen it to align the hole.
• Use needle-nose pliers to install and bend the new cotter pin securely.

Step 11: Tighten the Jam Nut

• Hold the outer tie rod end steady with a 17mm wrench if needed.
• Use a 19mm wrench to tighten the jam nut against the outer tie rod end.
• Tighten the jam nut firmly to Torque to 50-60 Nm (37-44 ft-lbs) if your torque wrench and crowfoot setup can fit.
• If using a crowfoot adapter, keep it at 90 degrees to the torque wrench handle for the most accurate torque.

Step 12: Reinstall the Wheel

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

Step 13: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack to lift the vehicle slightly off the jack stands.
• Remove the jack stands.
• Lower the vehicle fully to the ground.
• Use the 21mm lug nut socket and 1/2-inch drive torque wrench to tighten the wheel lug nuts in a star pattern to Torque to 88-107 Nm (65-79 ft-lbs).

✅ After Repair

• ✅ Turn the steering wheel left and right while parked. Listen for binding, popping, or scraping.
• ✅ Take a short, slow test drive. Keep speeds low until alignment is checked.
• ✅ Get a professional front wheel alignment as soon as possible. Tie rod length directly affects toe angle, which controls tire direction.
• ✅ Recheck the cotter pin, jam nut, and lug nut torque after the test drive.
• ✅ If the steering wheel is badly off-center or the vehicle pulls hard, do not continue driving except directly to an alignment shop.
