Replace the lower ball joint on a 2018-2024 Toyota Camry 2.5L I4 by removing the wheel, disconnecting steering/suspension components, and installing a new ball joint assembly.

Warnings

Tools required

Parts

• Lower ball joint assembly × 1 — Use OEM specification or equivalent quality
• Cotter pin for ball joint × 1 — Use OEM specification
• Lower control arm pinch bolt (if required) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Loosen wheel lug nuts 1/2 turn while vehicle is on ground
4. Raise front of vehicle with floor jack at designated jacking point
5. Support vehicle securely on jack stands under frame rails
6. Remove wheel and tire assembly completely

Procedure

1. 1

   Access lower ball joint
   Inspect the lower ball joint location on the steering knuckle. The ball joint stud passes through the lower control arm and is secured with a castle nut and cotter pin. Clean the area around the ball joint with a wire brush to remove debris and corrosion.
2. 2

   Remove ball joint cotter pin
   Straighten the cotter pin legs using needle nose pliers, then pull the cotter pin out from the castle nut. Discard the old cotter pin as it must not be reused.
3. 3

   Remove ball joint castle nut
   Using a 21mm socket, remove the castle nut from the ball joint stud. Keep the nut accessible as you may need to thread it back on partially during separation to protect the threads.
4. 4

   Separate ball joint from control arm
   Use a ball joint separator tool or pickle fork to break the taper connection between the ball joint stud and the lower control arm. Position the tool carefully to avoid damaging the control arm or knuckle. Thread the castle nut back on 2-3 turns to protect threads, then strike the separator tool or use the tool's forcing screw to separate the joint. Once separated, remove the castle nut completely.
   ⚠Pickle fork tools may damage ball joint boots. Use a proper ball joint separator if reinstalling the same joint.
5. 5

   Support steering knuckle
   Support the steering knuckle and brake assembly using a bungee cord or wire hung from the strut spring or frame. This prevents stress on the brake hose and ABS sensor wire when the ball joint is disconnected.
6. 6

   Remove ball joint from knuckle
   If the ball joint is bolted to the knuckle, remove the retaining bolts (typically 3-4 bolts accessed from behind the knuckle). If the ball joint is pressed or riveted into the knuckle, use appropriate removal tools or drill out rivets. For this Camry, the ball joint is typically an integrated part of the lower control arm assembly. If replacing ball joint only, remove the pinch bolt securing the ball joint to the knuckle if equipped.
7. 7

   Install new ball joint
   Clean the mounting surfaces on the steering knuckle thoroughly. Install the new ball joint assembly into the knuckle. If using bolts, start all bolts by hand before tightening. Ensure the ball joint seats fully into the knuckle taper. If a pinch bolt design, install new pinch bolt and torque immediately.

8. 8

   Connect ball joint stud to control arm
   Position the steering knuckle so the ball joint stud aligns with the hole in the lower control arm. Push the stud through the control arm. The taper should start to seat with hand pressure. Thread the new castle nut onto the ball joint stud by hand initially.
9. 9

   Torque ball joint nut and install cotter pin
   Torque the ball joint castle nut to specification using a torque wrench. If the castellations do not align with the cotter pin hole, tighten the nut further (never loosen) until the nearest castellation aligns. Insert a new cotter pin through the castle nut and ball joint stud, then bend the legs over to secure. Ensure the cotter pin cannot back out.
   ⚠Never loosen the castle nut to align cotter pin holes. Only tighten additional amount needed for alignment.

10. 10

    Reinstall wheel and lower vehicle
    Remove the support holding the steering knuckle. Reinstall the wheel and tire assembly. Thread all lug nuts by hand first. Snug lug nuts in a star pattern but do not torque yet. Lower the vehicle so the tires just touch the ground but most weight is still on jack stands.
11. 11

    Final torque wheel lug nuts
    Lower the vehicle completely to the ground. Torque the wheel lug nuts to specification in a star pattern using a torque wrench. Make at least two complete passes in the star pattern to ensure even torque distribution.
    Torque spec

    Wheel Lug Nuts136 Nm (100 lb-ft)

Reassembly

1. If control arm was loosened, final torque of control arm bolts must be performed with vehicle weight on suspension
2. Verify all fasteners are properly torqued and cotter pin is securely installed
3. Double-check that no tools or parts were left in the wheel well area

Verification

• Test drive vehicle at low speed and verify no unusual noises from front suspension
• Perform steering inputs while driving to confirm ball joint operates smoothly
• Check for any looseness or clunking when going over bumps
• Recheck wheel lug nut torque after 50-100 miles of driving
• Schedule a front end alignment as suspension geometry may have changed
