Steps

Replace the outer CV boot on a 2012-2017 Toyota Camry 2.5L I4 to prevent dirt and moisture contamination of the CV joint.

Warnings

⚠️Vehicle must be securely supported on jack stands before working underneath. Never rely on a floor jack alone.

⚠The axle nut is torqued to 250 Nm (184 lb-ft) and requires significant force to remove. Loosen while vehicle is on the ground with wheels chocked.

⚠CV grease can cause skin irritation. Wear nitrile gloves during boot installation and packing.

ℹ️Verify whether your specific VIN uses a cotter pin or staked axle nut design before beginning work.

Parts

Outer CV boot kit (includes boot, clamps, and grease) × 1 — Use OEM specification or aftermarket equivalent for 2AZ-FE engine
Axle nut (if staked type) × 1 — Use OEM specification
Cotter pin (if applicable to your VIN) × 1 — Use OEM specification

Preparation

Park vehicle on level surface and chock rear wheels
Loosen (but do not remove) the front axle nut on the side being serviced while vehicle is still on ground with brakes applied
Loosen wheel lug nuts 1/4 turn while vehicle is on ground
Raise front of vehicle and support securely on jack stands at manufacturer-specified lift points
Remove wheel and tire assembly completely
Clean the work area around CV joint and axle with wire brush to prevent contamination

Procedure

1
Remove axle nut and wheel components
Completely remove the previously loosened axle nut. If equipped with a cotter pin, remove and discard it first. If staked, use a chisel to unstake the nut before removal. Remove the axle nut washer and set aside.
Torque spec
Axle Nut250 Nm (184 lb-ft)
2
Disconnect lower ball joint
Remove the lower ball joint pinch bolt and nut. Use a ball joint separator or pickle fork to separate the lower control arm from the steering knuckle. Apply penetrating oil if joints are stubborn. Be careful not to damage the ball joint boot if reusing components.
3
Remove axle shaft from hub
Pull the steering knuckle outward while pushing the axle shaft inward to disengage the splines from the wheel hub. If the shaft is stuck, use a brass drift and hammer to tap it free from behind the hub. Support the axle shaft to prevent it from hanging on the inner CV joint.
⚠Do not allow the axle shaft to hang unsupported as this can damage the inner CV joint.
4
Remove old outer CV boot clamps
Use side cutters or a clamp cutting tool to cut and remove both the large and small clamps securing the outer CV boot. Slide the old boot toward the center of the axle shaft to expose the outer CV joint.
5
Clean CV joint and shaft
Wipe away all old grease from the CV joint housing, balls, cage, and axle shaft using shop towels. Inspect the CV joint for any wear, pitting, or damage. If the joint shows wear, the entire axle assembly should be replaced rather than just the boot. Clean the boot seating area on the axle shaft thoroughly.
ℹ️If CV joint shows clicking, popping, or visible wear damage, replace the entire axle assembly as the joint cannot be rebuilt economically.
6
Install new outer CV boot (small end)
Slide the new boot onto the axle shaft with the small end first. Position the small end of the boot in the groove on the axle shaft. Install the small clamp but do not fully tighten yet - leave it loose enough to allow adjustment.
7
Pack CV joint with grease
Pack the CV joint with the grease supplied in the boot kit. Distribute grease evenly into the CV joint housing, between the balls and cage. Use approximately half the grease packet for the joint itself. Place the remaining grease inside the new boot cavity.
ℹ️Use only the grease supplied with the CV boot kit. Different grease types are not compatible and can cause premature boot failure.
8
Position and secure boot
Slide the large end of the boot over the CV joint housing and seat it in the groove. Ensure the boot is not twisted and sits evenly in both grooves. Adjust the boot length to match the specification (boot should not be stretched or compressed). Tighten the small clamp using CV boot clamp pliers until secure. Install and tighten the large clamp in the same manner.
⚠Ensure no air is trapped inside the boot. Insert a small flat tool between boot and joint to equalize pressure before tightening large clamp.
9
Reinstall axle shaft into hub
Guide the axle shaft back through the wheel hub, ensuring the splines align properly. Push the shaft through until it seats completely. The splines should engage smoothly - do not force.
10
Reconnect lower ball joint
Reposition the lower control arm ball joint into the steering knuckle. Install the pinch bolt and nut, ensuring proper engagement. Tighten the ball joint pinch bolt to specification.
Torque spec
Mounting Bolts27 Nm (20 lb-ft)
11
Install axle nut
Place the axle nut washer onto the axle shaft. Thread on the axle nut by hand as far as possible. Do not torque yet - this will be done with the vehicle on the ground.
12
Reinstall wheel and lower vehicle
Install the wheel and tire assembly. Thread lug nuts by hand to prevent cross-threading. Snug lug nuts in a star pattern but do not fully torque yet. Lower vehicle until tire just contacts the ground but vehicle weight is still on jack stands.
13
Torque axle nut
Apply brakes (or have assistant apply brakes). Torque the axle nut to 250 Nm (184 lb-ft). If using a cotter pin style nut, install new cotter pin and bend ends. If using staked style nut, use a punch and hammer to stake the nut into the axle shaft groove.
⚠Never reuse a cotter pin or previously staked nut. Always use new hardware as specified.
Torque spec
Axle Nut250 Nm (184 lb-ft)
14
Final wheel installation
Completely lower vehicle to the ground and remove jack stands. Torque wheel lug nuts to 140 Nm (103 lb-ft) in a star pattern to ensure even seating of the wheel.
Torque spec
Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

Ensure all clamps are properly tightened and positioned in their grooves
Verify axle nut is properly staked or cotter pin is installed and secured
Double-check that all fasteners have been reinstalled and torqued to specification

Verification

Test drive vehicle at low speed and listen for any clicking or popping sounds from the CV joint during turns
Visually inspect the new CV boot for proper seating and ensure no grease is leaking
Turn steering wheel lock-to-lock while stationary and verify smooth operation without binding
After 50-100 miles, re-inspect boot clamps and check for any grease seepage indicating improper installation
