🔧 Legacy - Outer Tie Rod End Replacement
The outer tie rod end connects your steering rack to the steering knuckle. Replacing it fixes looseness, clunking, or uneven tire wear caused by a worn ball-and-socket joint.
Difficulty Level: Intermediate | Estimated Time: 1-2 hours (plus alignment)
⚠️ Safety & Precautions
- 🛑 Support your Legacy with jack stands before working under/near the suspension.
- 🧤 Wear safety glasses; rust and cotter pins can snap.
- 🔥 If you use penetrating oil, keep it off brake rotors/pads.
- 🧭 Plan for a professional alignment after replacement; even small changes affect tire wear.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 2-ton minimum)
- Jack stands (pair, rated 2-ton minimum)

📋 Before You Begin
- 🅿️ Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
- 🔎 Decide which side you’re replacing (left or right) and inspect the tie rod end nut for a cotter pin.
- 🧼 Use a wire brush and penetrating oil on the tie rod threads and jam nut 10 minutes before loosening.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Loosen the wheel lug nuts
- Use a 19mm socket and breaker bar to crack the front wheel lug nuts loose (about 1/4 turn) while the tire is still on the ground.
Step 2: Lift and support the front corner
- Use a floor jack to lift at the front pinch weld/jacking point.
- Set the car onto jack stands and lightly shake the car to confirm it’s stable.
- Remove the wheel using the 19mm socket.
Step 3: Mark the current position (helps get you to the alignment shop)
- Use a paint marker to mark the relationship between the outer tie rod end and the threaded inner tie rod.
- Use a tape measure to note a quick reference measurement (example: from the jam nut to the end of the threads).
- These marks are not a “real alignment.”
Step 4: Remove the cotter pin and loosen the tie rod end nut
- Straighten and remove the cotter pin using needle-nose pliers and side cutters if needed.
- Use a 17mm combination wrench to loosen/remove the tie rod end nut from the steering knuckle stud.
Step 5: Separate the tie rod end from the steering knuckle
- Install a tie rod end puller (specialty) on the joint and tighten it to pop the tapered stud free. (A puller is a clamp-style tool that presses the stud out without hammering.)
- Once it “pops,” remove the nut fully with the 17mm combination wrench and lift the tie rod end out of the knuckle.
Step 6: Loosen the jam nut
- Hold the inner tie rod (or the flats just behind the outer tie rod end) with a 19mm combination wrench as needed.
- Use a second 19mm combination wrench to loosen the jam nut (turn it counter-clockwise).
Step 7: Unscrew the old outer tie rod end (count turns)
- Spin the old outer tie rod end off by hand once loose.
- Count the exact number of turns it takes to remove it, and write it down.
Step 8: Install the new outer tie rod end
- Apply a very light coat of anti-seize compound to the threads.
- Screw the new outer tie rod end on using the same number of turns you counted during removal.
- Position the stud into the steering knuckle.
Step 9: Torque the tie rod end nut and install a new cotter pin
- Thread the nut on by hand first to avoid cross-threading.
- Use a torque wrench to tighten the nut: Torque to 45 Nm (33 ft-lbs).
- If the cotter pin hole doesn’t line up after torque, tighten the nut slightly more until it lines up (do not loosen to align).
- Install a new cotter pin and bend the ends using needle-nose pliers.
Step 10: Tighten the jam nut
- Hold the outer tie rod end with a 19mm combination wrench.
- Tighten the jam nut with a 19mm combination wrench: Torque to 70 Nm (52 ft-lbs).
Step 11: Reinstall the wheel
- Reinstall the wheel and hand-thread lug nuts.
- Lower the car using the floor jack and remove the jack stands.
- Use a torque wrench to tighten lug nuts in a star pattern: Torque to 120 Nm (89 ft-lbs).
✅ After Repair
- 🧪 Start the car and turn the steering wheel lock-to-lock while parked; listen for clicking/clunking.
- 🚗 Road test at low speed first; confirm the steering wheel is close to centered.
- 🧭 Get a 4-wheel alignment ASAP (same day if possible) to prevent tire wear.
- 🔍 Recheck for any looseness and visually confirm the cotter pin is installed.
