Lower Control Arm - Front

This procedure covers the removal and replacement of the front lower control arm on a 2012-2017 Toyota Camry with the 2.5L I4 engine.

Warnings

Tools required

Parts

• Front lower control arm × 1 — 48068-06180 or 48069-06180 (left/right specific)
• Ball joint castle nut × 1 — Replace if cotter pin hole is damaged
• Cotter pin × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Loosen front wheel lug nuts while vehicle is on ground (do not remove)
4. Raise front of vehicle with floor jack at manufacturer jacking point
5. Support vehicle securely on jack stands placed at designated lift points on frame rails
6. Remove front wheel completely

Procedure

1. 1

   Inspect and document control arm condition
   Visually inspect the lower control arm for damage, cracks, or excessive corrosion. Check the ball joint boot for tears and the bushings for deterioration. Take photos if needed for reference during reassembly.
2. 2

   Remove ball joint cotter pin and castle nut
   Locate the ball joint where it connects to the steering knuckle. Remove the cotter pin using pliers or a cotter pin removal tool. Unscrew the castle nut from the ball joint stud using a 19mm socket, but leave it threaded on a few turns to protect threads and prevent sudden separation.
3. 3

   Separate ball joint from steering knuckle
   Use a ball joint separator tool or pickle fork to break the taper between the ball joint stud and steering knuckle. Position the tool properly and strike with a hammer or use the screw-type tool to apply pressure. Once taper breaks free, remove the castle nut completely and separate the ball joint from the knuckle.
   ⚠The ball joint may release suddenly under spring tension. Keep hands and face clear of the separation point.
4. 4

   Remove rear control arm mounting bolt
   Locate the rear control arm mounting bolt that attaches the control arm to the subframe. This is typically a large bolt with bushing. Use a 19mm socket and wrench to hold the nut while loosening the bolt. Remove bolt completely and note any washers or spacers for reinstallation.
5. 5

   Remove front control arm mounting bolt
   Locate the front control arm mounting bolt at the forward subframe attachment point. Use a 17mm socket and wrench to remove this bolt. The control arm should now be free from the vehicle. Carefully maneuver it out from the suspension area.
6. 6

   Clean mounting surfaces and inspect hardware
   Use a wire brush to clean the control arm mounting points on the subframe and the ball joint taper seat on the steering knuckle. Remove any rust, dirt, or corrosion. Inspect all bolts for thread damage or excessive corrosion and replace if necessary. Apply penetrating oil to bolt holes if corrosion is present.
7. 7

   Install new control arm to subframe
   Position the new control arm into place. Install the front control arm bolt first, threading it through the bushing and subframe mount. Do not tighten yet. Then install the rear control arm bolt. Thread both bolts by hand initially to ensure proper alignment. Snug bolts finger-tight but do NOT torque at this stage.
   ⚠Control arm mounting bolts must NOT be torqued until suspension is at ride height in Step 10.
8. 8

   Connect ball joint to steering knuckle
   Lift the control arm ball joint into position and insert the stud through the steering knuckle hole. Ensure the stud seats fully into the taper. Install the castle nut and tighten it to specification. The nut slots must align with the cotter pin hole. If necessary, tighten further (never loosen) to align the next slot with the hole. Install a new cotter pin and bend the ends to secure.
   Torque spec

   Ball Joint Nut88 Nm (65 lb-ft)
9. 9

   Load suspension to ride height
   Place a hydraulic jack under the lower control arm or steering knuckle area. Carefully raise the jack to compress the suspension until it is at approximately normal ride height position. The suspension should be loaded and the control arm bushings should be in their natural operating position before torquing the mounting bolts.
   ⚠Ensure the jack is positioned securely and will not slip while torquing bolts.
10. 10

    Torque control arm mounting bolts at ride height
    With the suspension loaded to ride height, torque the front control arm bolt to 137 Nm (101 lb-ft) and the rear control arm bolt to 129 Nm (95 lb-ft). Use a torque wrench and verify proper tightening sequence. Once torqued, lower the hydraulic jack carefully.

11. 11

    Reinstall wheel and lower vehicle
    Place the wheel back onto the hub and hand-thread all lug nuts. Tighten lug nuts in a star pattern to snug them, but do not fully torque yet. Raise vehicle slightly with floor jack to remove jack stands, then lower vehicle completely to the ground.
12. 12

    Torque wheel lug nuts
    With the vehicle on the ground and full weight on the wheel, torque all lug nuts to specification in a star pattern using a torque wrench.

    Wheel Lug Nuts136 Nm (100 lb-ft)

Reassembly

1. Ensure all fasteners are torqued to specification and cotter pin is properly installed
2. Verify no tools or parts were left in the wheel well or suspension area
3. Double-check that control arm bolts were torqued at ride height to prevent bushing damage

Verification

• Test drive vehicle at low speed in a safe area and listen for any unusual noises from the front suspension
• Check for proper steering response and verify no pulling to either side
• After 50-100 miles of driving, re-check ball joint castle nut and control arm bolt torque
• Schedule a professional wheel alignment as soon as possible, as control arm replacement will affect alignment settings
