🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the wheel

• Use a 21mm socket and breaker bar to loosen the lug nuts 1/2 turn.
• Lift the front corner with a floor jack and place a jack stand under a solid lift point.
• Remove the lug nuts with the 21mm socket and remove the wheel.

Step 2: Mark your starting position (helps keep alignment close)

• Use a paint marker to mark the relationship between the tie rod end and the jam nut.
• Use a tape measure to measure from a fixed point on the tie rod end to a fixed point on the inner tie rod, and write it down.
• This helps the new part go on similarly.

Step 3: Loosen the jam nut

• Hold the inner tie rod area steady with a 19mm wrench if needed, and loosen the jam nut using a 17mm wrench.
• Only crack it loose (do not spin it far yet).

Step 4: Remove the cotter pin and castle nut

• Use needle-nose pliers to straighten and remove the cotter pin from the tie rod stud.
• Use a 17mm wrench to remove the castle nut from the tie rod stud.

Step 5: Separate the tie rod end from the steering knuckle

• Install and tighten a tie rod end puller (specialty) until the stud pops free.
• A tie rod end puller is a clamp-style tool that presses the stud out without damaging the joint.
• Keep fingers clear when it releases.

Step 6: Remove the old tie rod end (count turns)

• Spin the tie rod end off by hand, counting the exact number of turns it takes to remove.
• Write the number down (example: 17.5 turns).

Step 7: Install the new tie rod end

• Thread the new tie rod end on the same number of turns you counted, until it seats near your paint mark.
• Insert the stud into the steering knuckle by hand.
• Install the new castle nut by hand first to avoid cross-threading.
• Tighten the castle nut using a 17mm wrench: Torque to 49 Nm (36 ft-lbs), then tighten slightly more as needed to align the cotter pin hole.
• Install a new cotter pin using needle-nose pliers and bend the ends over securely.

Step 8: Tighten the jam nut

• Hold the tie rod end with a 19mm wrench and tighten the jam nut using a 17mm wrench.
• Torque to 74 Nm (55 ft-lbs).

Step 9: Reinstall the wheel and lower the car

• Reinstall the wheel and hand-thread the lug nuts.
• Lower the car off the jack stand using the floor jack.
• Torque the lug nuts in a star pattern using a torque wrench: Torque to 103 Nm (76 ft-lbs).

✅ After Repair

• Turn the steering wheel lock-to-lock while parked and listen for clunks or binding.
• Test drive slowly and confirm the steering feels normal and the wheel returns to center.
• Recheck that the cotter pin is installed and the jam nut is tight.
• Schedule a 4-wheel alignment as soon as possible to prevent tire wear.
