🔧 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)
  • Wheel chocks
  • 19mm socket
  • Breaker bar (1/2" drive)
  • Torque wrench (20-150 ft-lbs range)
  • 17mm combination wrench
  • 19mm combination wrench
  • Needle-nose pliers
  • Side cutters
  • Tie rod end puller (specialty)
  • Wire brush
  • Penetrating oil
  • Paint marker
  • Tape measure
  • Nitrile gloves
  • Safety glasses

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Outer tie rod end - Qty: 1
  • Cotter pin (new) - Qty: 1
  • Anti-seize compound - Qty: 1

📋 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.

💰 DIY vs Shop Cost

Shop Cost: ₹4,500-₹9,000 (parts + labor, not including alignment)

You Save: ₹3,300-₹5,500 by doing it yourself!
