This procedure covers removal and installation of the front lower control arm on a 2018-2024 Toyota Camry with 2.5L I4 engine, including ball joint separation and proper ride height torquing.

Warnings

Tools required

Parts

• Lower control arm assembly × 1 — OEM or equivalent for 2018-2024 Camry
• Cotter pin for ball joint × 1 — Use OEM specification
• Control arm bushing bolts (if corroded) × 2 — Use OEM specification

Preparation

1. Park vehicle on level ground and set parking brake
2. Loosen wheel lug nuts 1/4 turn while vehicle is on ground
3. Raise front of vehicle with floor jack and support securely on jack stands at manufacturer-specified jacking points
4. Remove wheel completely
5. Spray penetrating oil on control arm bolts, ball joint nut, and sway bar link connections. Allow to soak 10-15 minutes

Procedure

1. 1

   Remove ball joint cotter pin and nut
   Locate the lower ball joint where it connects to the steering knuckle. Use cotter pin puller or needle-nose pliers to remove and discard the cotter pin. Using a 22mm socket, remove the ball joint castle nut completely. Do not reuse the old cotter pin.
2. 2

   Separate ball joint from knuckle
   Install ball joint separator tool between the lower control arm and steering knuckle. Tighten tool to apply pressure, then strike the knuckle boss area sharply with a hammer to shock the taper loose. Alternatively, use a pickle fork pressed between the joint. Once separated, support the knuckle to prevent stress on the brake hose and ABS sensor wire.
   ⚠Ball joint will separate suddenly. Keep hands clear and ensure knuckle is supported to prevent damage to brake lines and ABS wiring.
3. 3

   Disconnect sway bar link (if necessary)
   If the sway bar link interferes with control arm removal, disconnect it from the lower control arm. Use a 17mm wrench to hold the ball stud and a socket on the nut to remove. Note the orientation of washers and bushings for reinstallation.
4. 4

   Remove rear control arm bolt
   Locate the rear control arm mounting bolt at the rear bushing connection point to the subframe. This is typically a 19mm bolt. Support the control arm with a jack or by hand. Remove the bolt completely. The control arm will now pivot on the front bolt only.
5. 5

   Remove front control arm bolt
   Locate the front control arm mounting bolt at the front bushing connection to the subframe. This is typically a 19mm bolt. Remove this bolt completely. The control arm is now free and can be removed from the vehicle. Inspect the bolt holes in the subframe for damage or corrosion.
6. 6

   Inspect and prepare new control arm
   Compare the new control arm to the old one to ensure correct fitment. Check that ball joint dust boot is intact and ball joint has no play. Clean mounting bolt holes in subframe with wire brush. Inspect subframe bushing mounting points for cracks or damage.
7. 7

   Install new control arm loosely
   Position new control arm into place. Insert front control arm bolt finger-tight first, then insert rear control arm bolt finger-tight. Do NOT torque these bolts yet - they must be torqued at ride height. Hand-tighten both bolts just enough to hold the control arm in position.
   ⚠️Do NOT torque control arm bolts at this stage. Bolts must be torqued with vehicle weight on suspension at ride height to prevent bushing bind and premature failure.
8. 8

   Connect ball joint to knuckle
   Guide the ball joint stud into the steering knuckle. Install the castle nut and tighten to specification using a torque wrench. The nut should align with the cotter pin hole. If necessary, tighten further (never loosen) to align the castle nut slots with the hole. Install new cotter pin and bend ends to secure.

9. 9

   Reconnect sway bar link (if disconnected)
   If sway bar link was disconnected, reconnect it to the lower control arm ensuring all bushings and washers are in correct position. Torque the sway bar link nut to specification while holding the ball stud with a wrench.

   Sway Bar Link61 Nm (45 lb-ft)
10. 10

    Install wheel and lower vehicle to ride height
    Install the wheel and thread all lug nuts by hand. Lower the vehicle from jack stands so that the full weight of the vehicle is on the suspension (ride height). The vehicle should be on level ground. Do not let vehicle bounce or roll before torquing control arm bolts.
11. 11

    Torque control arm bolts at ride height
    With vehicle weight fully on the wheels at 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). These bolts must be torqued in this loaded condition to properly preload the bushings. Do not allow the vehicle to be driven or moved until these bolts are properly torqued.
    ⚠️Control arm bolts MUST be torqued at ride height with suspension loaded. This is critical for bushing longevity and vehicle handling.

12. 12

    Torque wheel lug nuts
    Torque all wheel lug nuts to specification in a star pattern to ensure even seating of the wheel. Make multiple passes, gradually increasing torque until final specification is reached.

    Wheel Lug Nuts136 Nm (100 lb-ft)

Reassembly

1. Control arm mounting bolts must always be torqued at ride height, not with suspension hanging
2. Always use a new cotter pin for the ball joint - never reuse the old one
3. Verify sway bar link bushings are properly seated if link was disconnected

Verification

• Verify ball joint cotter pin is properly installed and bent to prevent nut loosening
• Confirm all fasteners are torqued to specification, especially control arm bolts at ride height
• Test drive vehicle at low speed and verify no clunking, knocking, or unusual handling
• Recheck all fastener torque after 50-100 miles of driving
• Schedule alignment check within one week - control arm replacement affects alignment settings
