2021 - 2025 Chevrolet Trailblazer Rear Axle Shaft - Front Right (Passenger) (OEM)

What to Look For When Buying a Rear Axle Shaft

• Compatibility: Ensure the axle shaft is designed for the right (passenger) side of your specific vehicle model and year.
• Condition: Carefully inspect the axle shaft for any signs of damage, such as cracks, bends, or corrosion.
• Material: Look for an axle shaft made from high-quality steel for strength and durability.

Quality Indicators

• OEM (Original Equipment Manufacturer) Markings: OEM parts are made to the same specifications as the original part in your vehicle.
• Testing and Inspection: Ensure the part has been thoroughly tested and inspected to meet quality standards.
• Warranty: A warranty can provide peace of mind and protection against defects.

What's Included

Typically, a rear axle shaft assembly includes:

• The axle shaft itself.
• Sometimes includes the wheel studs.
• May or may not include the axle bearing and seal. Check the product description carefully.

Difficulty Level and Estimated Time

Replacing a rear axle shaft is generally considered a medium-difficulty repair. Estimated time: 2-4 hours.

Special Tools Needed

• Jack and jack stands
• Wheel chocks
• Socket set and wrenches
• Torque wrench
• Hammer
• Punch or chisel
• Axle puller (may be required)
• Bearing press (may be required)

Critical Steps and Tips

1. Safely lift and support the vehicle.
2. Remove the wheel and brake components.
3. Disconnect the ABS sensor (if applicable).
4. Remove the old axle shaft, possibly requiring an axle puller.
5. Install the new axle shaft, ensuring proper alignment.
6. Reassemble the brake components and wheel.
7. Torque all fasteners to the manufacturer's specifications.

DIY or Professional Installation?

While it's possible to replace a rear axle shaft yourself, professional installation is recommended if you lack experience or the necessary tools. A professional can ensure the job is done correctly and safely.

There are several options when buying a replacement rear axle shaft: Used OEM, Refurbished OEM, and New Aftermarket. Each has its own advantages.

Used OEM: Offers the best value. You get a genuine factory part that has been tested and inspected, at a significantly lower price than new.

Refurbished OEM: A good option if you want a factory part that has been professionally restored with new components.

New Aftermarket: Provides a brand new part built to OE specs, ensuring proper fit and function.

• Wheel Bearings: These support the axle shaft and allow the wheels to rotate smoothly. Worn wheel bearings can cause noise, vibration, and premature axle shaft failure.
• Axle Seals: These prevent oil leaks from the axle housing. Damaged seals can lead to lubrication problems and axle shaft damage.
• Brake Components: Inspect brake pads, rotors, and calipers. Problems here can cause uneven wear and stress on the axle.

Replacing these parts at the same time can prevent repeat failures and save you time and money in the long run.

A rear axle shaft can last for many years, often exceeding 100,000 miles or more.

Factors Affecting Longevity

• Driving habits (aggressive driving can shorten lifespan).
• Road conditions (rough roads can cause damage).
• Maintenance (proper lubrication is crucial).
• Towing or carrying heavy loads (puts extra stress on the axle).

• Used OEM: $100 - $300
• Refurbished OEM: $200 - $400
• New Aftermarket: $150 - $350

Labor Cost Considerations

Professional installation can add $200 - $500 to the total cost, depending on the shop's labor rate and the complexity of the job.

Total Job Cost Estimates

• DIY (Used OEM): $100 - $300 (plus the cost of any needed tools)
• Professional Installation (Used OEM): $300 - $800
• Professional Installation (New Aftermarket): $350 - $850

Some 2020-2025 Buick Encore GX and Chevrolet Trailblazer models have experienced issues with premature rear wheel bearing failure, which can put extra stress on the axle shaft. Regularly inspect the rear wheel bearings for any signs of wear or play. Check for any applicable Technical Service Bulletins (TSBs) related to the rear axle or wheel bearings on these vehicles.

How to Confirm Proper Operation

1. Visual Inspection: Check for any leaks around the axle seals.
2. Test Drive: Drive the vehicle at various speeds and listen for any unusual noises coming from the rear axle area.
3. Steering Check: Ensure the vehicle tracks straight and there is no excessive play in the steering.

What to Look/Listen For

• No clicking, popping, or grinding noises when turning or accelerating.
• No vibrations felt in the vehicle.
• Smooth and quiet operation of the rear axle.

FAQ

Q: How do I know if my rear axle shaft is bent?
A: A bent axle shaft can cause vibrations, uneven tire wear, and difficulty steering. A visual inspection may reveal the bend, or a mechanic can use specialized tools to check for runout.

Q: Can I drive with a damaged rear axle shaft?
A: It is not recommended to drive with a damaged rear axle shaft. It can be dangerous and lead to further damage to other components.

Q: What is the difference between an axle shaft and an axle bearing?
A: The axle shaft is the rotating rod that transmits power from the differential to the wheels. The axle bearing supports the axle shaft and allows it to rotate smoothly.

Q: How often should I replace my rear axle shaft?
A: There is no set replacement interval for a rear axle shaft. It should be replaced when it shows signs of damage or wear.

Q: Will replacing the axle shaft fix my noisy rear end?
A: Replacing the axle shaft may fix a noisy rear end if the noise is caused by a damaged axle shaft. However, other components, such as the wheel bearings or differential, could also be the source of the noise.
