Tools:
* Jack and jack stands: Essential for safely lifting the vehicle. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheel.
* Torque wrench: Crucial for tightening bolts to the manufacturer's specifications. Improper torque can lead to premature failure or damage.
* Sockets and ratchets: A variety of sizes will be needed, depending on the specific bolts and nuts involved. Check a repair manual for the correct sizes.
* Hammer: Possibly needed to break loose stubborn parts.
* Pry bar or a ball joint separator: May be required to separate the ball joint from the control arm. A pickle fork is generally discouraged as it can damage the ball joint.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized bolts and fasteners. Apply generously and let it soak for a while before attempting to remove anything.
* Wheel alignment tool (optional but recommended): After replacing the hub assembly, a wheel alignment is almost always necessary. You may need to have it done professionally.
Parts:
* New front wheel hub assembly: Make sure you get the correct one for your specific Grand Am model (check your VIN or parts diagrams).
* New wheel bearing: Sometimes sold separately; check if the new hub assembly includes it. It's a good idea to replace the bearing if the old one shows any signs of wear.
* New cotter pin: To secure the castle nut.
* New lug nuts (optional but recommended): Although not strictly necessary, replacing the lug nuts ensures they're in good condition.
Additionally:
* Repair manual: A service manual specific to your 2003 Pontiac Grand Am is highly recommended. It will provide detailed instructions, torque specifications, and diagrams. You can find these online or at auto parts stores.
* Safety glasses and gloves: Protect yourself from flying debris and potential injuries.
* Clean workspace: Makes the job easier and less frustrating.
Important Notes:
* This is a moderately challenging job requiring some mechanical aptitude. If you're not comfortable working on your car, it's best to take it to a qualified mechanic.
* Failure to follow proper procedures can lead to serious injury or damage to your vehicle.
* Always refer to your repair manual for specific instructions and torque specifications. Torque specifications are critical for safety and component longevity.
Remember to consult a repair manual for your specific vehicle before attempting this repair. Improper installation can lead to serious consequences.
