This procedure covers the removal and replacement of the rear axle seals on a 2014-2019 Toyota Corolla with 1.8L I4 engine, which requires removing the rear axle shafts to access the seals.

Warnings

⚠️Vehicle must be properly supported on jack stands. Never work under a vehicle supported only by a floor jack.

⚠Axle nuts require very high torque (250 Nm). Ensure proper tools and technique to prevent injury.

⚠Differential fluid will drain when axles are removed. Have drain pan ready and dispose of fluid properly.

ℹ️This procedure assumes a rear beam axle design with sealed bearing hubs common to FWD Corollas. Some fluid loss is inevitable when removing axle shafts.

Preparation

Park vehicle on level ground and engage parking brake
Loosen rear wheel lug nuts while vehicle is on ground (do not remove)
Raise rear of vehicle and support securely on jack stands at manufacturer-recommended lift points
Remove both rear wheels completely
Place drain pan under differential area to catch gear oil
Clean area around axle nuts and differential to prevent contamination

Procedure

1
Remove axle nut
Have an assistant apply brakes or use a pry bar to prevent hub rotation. Use a breaker bar or impact wrench to remove the 30mm axle nut. If nut is staked (common), it must be replaced with a new one. Remove and discard the axle nut and any cotter pin or locking washer if present.
2
Disconnect brake components if necessary
If brake drum or disc prevents axle removal, remove the brake drum (drum brake models) or brake caliper mounting bolts (disc brake models). For disc brakes, support caliper with wire - do not let it hang by the brake hose. Remove rotor if equipped with rear disc brakes.
3
Remove axle shaft from hub
Pull the axle shaft outward from the hub assembly. The shaft should slide out of the hub bearing. If resistance is encountered, tap gently on the end of the shaft with a soft mallet or use a hub puller. Be careful not to damage the ABS sensor ring if equipped.
⚠Do not damage the ABS sensor or tone ring during axle removal.
4
Remove axle shaft from differential
Carefully pull the inner end of the axle shaft straight out from the differential carrier. Differential gear oil will drain out at this point - ensure drain pan is positioned properly. Use a pry bar if needed, being careful not to damage the differential housing or internal components. Remove axle shaft completely from vehicle.
⚠Gear oil will spill when axle is removed. Keep drain pan in position.
5
Remove old axle seal
Using a seal puller or pry bar, carefully extract the old axle seal from the differential housing. Work carefully to avoid gouging or scratching the seal bore in the housing. Note the orientation and depth of the seal for installation reference. Clean the seal bore thoroughly with brake cleaner and a shop towel.
6
Inspect and clean components
Inspect the axle shaft splines and seal contact surface for wear, scoring, or damage. Check the differential housing seal bore for any damage. Clean the axle shaft thoroughly with brake cleaner, paying special attention to the seal contact area. Inspect hub bearing for excessive play or noise (replace if necessary, though not part of this procedure).
7
Install new axle seal
Lightly coat the outer diameter of the new seal with differential gear oil. Position the seal squarely in the differential housing bore with the lip facing inward (toward the differential). Using a seal driver or appropriately sized socket that contacts only the outer edge of the seal, carefully drive the seal into the housing until it is flush or seated to the same depth as the original seal.
⚠Do not drive seal in crooked or strike the seal face directly as this will damage the seal.
8
Install axle shaft into differential
Coat the axle shaft splines and seal lip with fresh differential gear oil. Carefully align the inner end of the axle shaft with the differential side gear and push it straight in until it fully seats. You should feel it engage with the side gear splines. Ensure the axle shaft is fully inserted and properly engaged.
9
Install axle shaft into hub
Align the outer end of the axle shaft with the hub bearing and push it through until it is fully seated. The shaft should slide smoothly through the bearing. If equipped with rear disc brakes, install the rotor at this time.
10
Reinstall brake components
If brake components were removed, reinstall them now. For disc brakes, install the caliper and torque mounting bolts per specification. For drum brakes, install the brake drum. Ensure all brake components are properly secured.
11
Install and torque axle nut
Install the new axle nut onto the axle shaft. Have an assistant apply brakes or use a pry bar to prevent hub rotation. Torque the axle nut to specification. After torquing, stake the nut into the shaft groove using a punch and hammer, or install a new cotter pin if that style is used on your vehicle.
⚠Axle nut must be properly staked or pinned to prevent loosening. Follow the specific retention method for your vehicle.
Torque spec
Axle Nut250 Nm (184 lb-ft)
12
Repeat for opposite side
Perform steps 1 through 11 for the opposite rear axle seal if replacing both sides (recommended).
13
Refill differential gear oil
Locate the differential fill plug (typically on the front or side of the differential housing). Remove the fill plug and add Toyota Genuine Differential Gear Oil 75W-85 GL-5 until it reaches the bottom of the fill hole (oil should just start to run out). Install and tighten the fill plug. Clean any spilled oil from the differential housing.
14
Reinstall wheels and lower vehicle
Install both rear wheels and hand-tighten the lug nuts. Lower the vehicle until the wheels just contact the ground (to prevent rotation). Torque the wheel lug nuts in a star pattern to specification. Fully lower the vehicle and remove jack stands.
Torque spec
Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

Ensure both axle nuts are properly torqued and secured with staking or cotter pins
Verify differential is filled to proper level with correct gear oil
Double-check that all brake components are properly reinstalled and secured
Confirm wheel lug nuts are torqued in proper star pattern

Verification

Test drive vehicle at low speed and verify no unusual noises from rear axle area
Check for any gear oil leaks around the new axle seals after test drive
Verify proper brake operation during test drive
Re-check differential fluid level after test drive and top off if necessary
Inspect axle nut staking or cotter pin installation to ensure proper retention
After 50-100 miles, re-check for any leaks and verify axle nuts remain tight
