Difficulty: Advanced · About 110 min · Cadillac Cts

Replace a front CV axle on a 2008–2014 Cadillac CTS, freeing the outer joint from the hub and inner joint from the differential before reconnecting the steering and ABS components.

Steps

1. Remove the wheel and axle nut

   Loosen the lug nuts and axle nut with the vehicle on the ground, then raise and support it securely. Remove the wheel and axle nut, using a suitable holder to keep the hub from turning.

2. Free the axle from the steering knuckle

   Tap the axle end inward to release it from the hub splines. Unplug and move the ABS sensor lead, free the brake hose bracket, then disconnect the tie rod and upper ball joint from the knuckle.

3. Remove the old axle

   Pull the knuckle outward and guide the outer axle stub from the hub. Use an axle fork or pry bar to release the inner joint from the differential, catching any fluid that escapes.

4. Install the replacement axle

   Apply a light coat of suitable grease to the inner and outer splines. Seat the inner joint fully in the differential, pass the outer end through the hub, and reconnect the upper ball joint and tie rod.

5. Reconnect the ABS and brake brackets

   Tighten the steering fasteners to the vehicle's specifications and secure the brake hose bracket. Reinstall the ABS sensor and route its wire through the original retainers without twisting it.

6. Secure the axle and reinstall the wheel

   Install a new axle nut if required and tighten it to the vehicle's specification. Refit the wheel, torque its lug nuts in a crossing pattern, check transmission fluid level, and verify the ABS wire is clear.

Check your vehicle’s repair manual for exact specifications and fit.
