This procedure covers the removal and replacement of the outer tie rod end on a 2014-2019 Toyota Corolla, requiring an alignment after completion.

Warnings

Tools required

Parts

• Outer tie rod end × 1 — Use OEM specification or quality aftermarket
• Cotter pin × 1 — 90179-04127 or equivalent

Preparation

1. Park vehicle on level surface and apply parking brake
2. Loosen wheel lug nuts while vehicle is on ground
3. Raise front of vehicle and support securely on jack stands at the frame jacking points
4. Remove wheel completely
5. Spray penetrating oil on tie rod lock nut and castle nut threads, allow to soak for 10-15 minutes

Procedure

1. 1

   Remove cotter pin from castle nut
   Locate the castle nut on the outer tie rod end where it connects to the steering knuckle. Straighten the cotter pin legs with needle nose pliers, then pull the cotter pin completely out and discard it. Clean any rust or debris from the castle nut.
2. 2

   Mark tie rod position
   Before loosening anything, use a paint marker to mark the exact position where the outer tie rod end threads onto the inner tie rod. Count and record the number of visible threads. This reference mark will help maintain approximate alignment during installation and minimize post-repair alignment adjustments.
3. 3

   Loosen tie rod lock nut
   Using a 17mm wrench, loosen the lock nut that secures the outer tie rod end to the inner tie rod. Do not remove it completely yet - back it off several turns until it is against the outer tie rod end body. This nut is located on the threaded shaft between the inner and outer tie rod ends.
4. 4

   Remove castle nut
   Using a 19mm socket, remove the castle nut from the tie rod end ball stud where it connects to the steering knuckle. Remove the nut completely and set aside.
5. 5

   Separate tie rod end from knuckle
   Install a tie rod end separator or pickle fork between the tie rod end and steering knuckle. Strike the separator tool firmly with a hammer to pop the ball stud taper free from the knuckle. Alternatively, use a ball joint separator tool. Once separated, pull the tie rod end ball stud completely out of the knuckle.
6. 6

   Remove outer tie rod end
   Hold the inner tie rod with a 21mm wrench to prevent it from spinning. Unscrew the outer tie rod end counterclockwise by hand, counting the number of turns. The lock nut will slide along with it. Remove both the outer tie rod end and lock nut completely.
7. 7

   Clean threads and install new tie rod end
   Clean the threads on the inner tie rod with a wire brush. Thread the lock nut onto the new outer tie rod end first (it should slide freely along the shaft). Apply a light coat of anti-seize to the inner tie rod threads. Thread the new outer tie rod end onto the inner tie rod clockwise, using the same number of turns counted during removal and aligning with your reference mark.
8. 8

   Install tie rod end into knuckle
   Insert the ball stud of the new outer tie rod end into the steering knuckle hole. Ensure the stud is fully seated and the taper is properly engaged. Thread the castle nut onto the ball stud by hand first, then tighten to specification using a 19mm socket and torque wrench.
   Torque spec

   Tie Rod End Castle Nut55 Nm (41 lb-ft)
9. 9

   Install new cotter pin
   Align the castle nut slots with the hole in the ball stud. If necessary, tighten the castle nut slightly (do not loosen) until the slots align with the hole. Insert a new cotter pin through the hole and bend the legs in opposite directions to secure it. Ensure the cotter pin cannot come loose.
10. 10

    Reinstall wheel
    Position the wheel onto the hub and thread all lug nuts by hand. Lower the vehicle until the tire just touches the ground to prevent wheel rotation. Torque the lug nuts in a star pattern to specification.
    Torque spec

    Wheel Lug Nuts129 Nm (95 lb-ft)
11. 11

    Final tightening and alignment preparation
    Lower the vehicle completely to the ground. Do not tighten the tie rod lock nut yet. Note that the lock nut must only be torqued to specification AFTER the vehicle has been professionally aligned. Mark the vehicle for immediate alignment service.

Reassembly

1. After professional alignment is completed, torque the tie rod lock nut to 64 Nm (48 lb-ft) while holding the inner tie rod with a 21mm wrench
2. Verify the cotter pin is properly installed and secure
3. Test drive the vehicle at low speed in a safe area to verify proper steering operation before normal use

Verification

• Verify the outer tie rod end ball stud moves freely without binding when the steering wheel is turned
• Check that the cotter pin is properly installed and secure
• Confirm there is no play or looseness in the tie rod connection by attempting to move the tie rod end by hand with the wheel on the ground
• Schedule and complete a professional front end alignment immediately - verify toe, camber, and caster are within specification
• After alignment, verify the tie rod lock nut has been torqued to 64 Nm (48 lb-ft)
• Test drive and verify steering feels normal with no pulling or unusual feedback
