This procedure covers the removal and replacement of the idler arm on a 2012-2017 Toyota Camry with 2.5L I4 engine. Note: Toyota Camrys of this generation use rack and pinion steering and do not have a traditional idler arm.

Warnings

Tools required

Parts

• Idler arm assembly × 1 — Use OEM specification
• Cotter pin (if equipped with castle nut) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Loosen front wheel lug nuts while vehicle is on ground (do not remove)
3. Raise front of vehicle with floor jack and support securely on jack stands at designated lift points
4. Remove both front wheels completely
5. Spray all suspension fasteners with penetrating oil and allow to soak for 10-15 minutes

Procedure

1. 1

   Verify component identification
   Inspect the steering system to confirm which component requires replacement. The 2012-2017 Camry does not use a traditional idler arm. If replacing a tie rod end or steering link, proceed with appropriate steps. If the issue was misdiagnosed, consult a steering diagram for this vehicle model.
2. 2

   Access steering linkage
   From beneath the vehicle, locate the outer tie rod end on the affected side. Remove any splash shields or covers that obstruct access to the tie rod connection at the steering knuckle.

3. 3

   Mark tie rod position
   Before removal, count and record the number of exposed threads on the tie rod end. Mark the tie rod position with paint or marker relative to the adjustment sleeve. This preserves the approximate wheel alignment setting.
4. 4

   Remove cotter pin and castle nut
   Remove the cotter pin from the tie rod castle nut using pliers or side cutters. Unscrew the castle nut from the tie rod stud. Do not fully remove the nut yet - back it off to be flush with the top of the stud to protect threads during separation.

5. 5

   Separate tie rod from knuckle
   Using a tie rod separator tool or pickle fork, separate the tie rod end from the steering knuckle. Position the tool between the tie rod taper and knuckle, then strike with a hammer or tighten the screw-type separator. Once the taper releases, remove the castle nut completely and remove the tie rod end from the knuckle.
6. 6

   Remove tie rod end from rack
   Hold the flat surfaces of the tie rod with a wrench to prevent rotation. Loosen and unscrew the tie rod end from the steering rack or center adjustment sleeve by turning counterclockwise. Count the rotations needed for removal to aid in reinstallation alignment.
7. 7

   Install new component
   Clean the threads on the steering rack or adjustment sleeve with a wire brush. Thread the new tie rod end onto the rack the same number of turns counted during removal, aligning with the reference marks made earlier. Verify the exposed thread count matches the original component.
8. 8

   Connect tie rod to knuckle
   Insert the tie rod stud into the steering knuckle taper. Install the castle nut and tighten to specification. Ensure the cotter pin holes align. If they do not align, tighten the nut slightly more (never loosen) until holes align.

9. 9

   Install new cotter pin
   Insert a new cotter pin through the castle nut and tie rod stud. Bend the ends of the cotter pin in opposite directions to secure it in place. Ensure the pin cannot work loose.
10. 10

    Reinstall protective covers
    Reinstall any splash shields or covers removed for access. Torque all cover screws to specification.

    Reinstall wheels
    Install both front wheels and hand-tighten lug nuts in a star pattern. Lower the vehicle to the ground, then torque lug nuts to specification in a star pattern.

Reassembly

1. Double-check that all fasteners are torqued to specification
2. Verify the cotter pin is properly installed and secured
3. Ensure no tools or parts were left in the wheel well or under the vehicle

Verification

• Start the engine and turn the steering wheel lock-to-lock while stationary to check for binding or unusual noises
• Test drive the vehicle at low speed in a safe area and verify steering response
• Schedule a professional wheel alignment as soon as possible - alignment will be affected even with careful measurement
• Re-check all fastener torque after 50-100 miles of driving
