2021 - 2025 Chevrolet Trailblazer Rear Stabilizer Bar - Front (OEM)

Before you buy a replacement rear stabilizer bar, consider these points:

• Check the Bushings: Are new bushings included? If not, factor in the cost of buying them separately.
• Inspect for Damage: If buying a used part, carefully inspect it for rust, cracks, or bends.
• Verify Compatibility: While this part fits specific Buick and Chevy models from 2020-2025, double-check that it's the correct part for your exact year and trim level.
• Consider the Links: Stabilizer bar links often wear out at the same time as the bar. Think about replacing them together.

Quality indicators:

• Solid Construction: The bar should be made of strong, durable steel.
• Good Bushings: The bushings should be made of high-quality rubber or polyurethane.
• Clean Finish: The bar should have a clean, rust-resistant finish.

What's typically included:

• The stabilizer bar itself.
• Sometimes, new bushings are included. Check the product description.
• Stabilizer bar links are usually sold separately.

Replacing the rear stabilizer bar is a moderately difficult job.

• Difficulty Level: Medium
• Estimated Time: 1-2 hours

Special tools needed:

• Socket set
• Wrench set

• Penetrating oil
• Torque wrench

Critical steps and tips:

1. Loosen the lug nuts on the rear wheels.
2. Jack up the rear of the car and support it with jack stands.
3. Remove the rear wheels.
4. Spray penetrating oil on the stabilizer bar link bolts and bushing brackets.
5. Remove the stabilizer bar links from the stabilizer bar.
6. Remove the bushing brackets.
7. Remove the old stabilizer bar.
8. Install the new stabilizer bar, bushing brackets, and links.
9. Torque all bolts to the manufacturer's specifications.

DIY or professional installation?

• If you have experience working on cars and have the necessary tools, you can probably do this job yourself.
• If you're not comfortable working on cars, it's best to have a professional install the stabilizer bar.

Here's a comparison of your options when buying a rear stabilizer bar:

• Used OEM: These are genuine factory parts taken from used vehicles. They offer excellent value because they're tested, inspected, and priced lower than new parts.
• Refurbished OEM: These are factory parts that have been professionally restored. They may have new bushings or other components.
• New Aftermarket: These are brand new parts made by third-party manufacturers. They are designed to meet or exceed OE specifications.

Used OEM:

• Pros: Lowest price, genuine factory part, typically inspected.
• Cons: May have some wear and tear.

Refurbished OEM:

• Pros: Restored to like-new condition, may include new components.
• Cons: More expensive than used OEM.

New Aftermarket:

• Pros: Brand new, readily available.
• Cons: May not be as durable as OEM parts.

All three options can be a good choice depending on your budget and needs.

Consider replacing these parts at the same time as the rear stabilizer bar:

• Stabilizer Bar Links: These connect the stabilizer bar to the suspension. They often wear out at the same time as the bar.
• Stabilizer Bar Bushings: These hold the stabilizer bar in place. They can dry out and crack over time.
• Rear Shocks or Struts: If your shocks or struts are worn, they can put extra stress on the stabilizer bar.

Replacing these parts together can prevent repeat failures and improve your car's handling.

A rear stabilizer bar typically lasts for 75,000 to 100,000 miles.

Factors that affect longevity:

• Driving Conditions: Driving on rough roads or in areas with salt can shorten the lifespan of the stabilizer bar.
• Maintenance: Regularly inspecting and lubricating the stabilizer bar bushings can help extend its life.
• Accidents: Even minor accidents can damage the stabilizer bar.

Here's a general idea of what you can expect to pay for a rear stabilizer bar:

• Used OEM: $50 - $100
• Refurbished OEM: $75 - $150
• New Aftermarket: $100 - $200

Labor costs:

• If you choose to have a professional install the stabilizer bar, expect to pay $100 - $200 in labor.

Total job cost estimates:

• DIY (Used OEM): $50 - $100 (plus the cost of any needed tools)
• Professional Installation (Used OEM): $150 - $300
• Professional Installation (New Aftermarket): $200 - $400

Some 2020-2025 Buick Encore GX and Chevy Trailblazer models have been known to experience premature wear of the stabilizer bar bushings. This can lead to clunking noises and reduced handling performance. Regularly inspecting and lubricating the bushings can help prevent this issue. There are no specific TSBs (Technical Service Bulletins) related to the rear stabilizer bar itself, but check for any suspension-related TSBs that might apply to your vehicle.

After installing the new rear stabilizer bar, check the following:

• Test Drive: Take the car for a test drive and listen for any noises.
• Handling: Pay attention to how the car handles in turns. It should feel more stable and controlled.
• Visual Inspection: Double-check that all bolts are tightened to the correct torque specifications.
• Noises: Listen for any clunking or squeaking noises coming from the rear suspension.

If you notice any problems, re-inspect the installation and make sure everything is properly installed and tightened.

Q: How do I know if my stabilizer bar links are bad?
A: Bad stabilizer bar links can cause clunking noises, especially when going over bumps. You may also notice loose steering or poor handling.

Q: Can I drive with a broken stabilizer bar?
A: It's not recommended. A broken stabilizer bar can make your car unstable and difficult to control, especially in turns.

Q: Are aftermarket stabilizer bars as good as OEM?
A: Some aftermarket stabilizer bars are very good quality and can perform as well as or even better than OEM parts. However, it's important to choose a reputable brand.

Q: Do I need to replace the bushings when I replace the stabilizer bar?
A: Yes, it's highly recommended. The bushings are often worn out by the time the stabilizer bar needs replacing. New bushings will ensure proper performance and prevent future problems.

Q: How often should I grease my stabilizer bar bushings?
A: It depends on the type of bushings you have. Some bushings are self-lubricating, while others need to be greased periodically. Check your vehicle's service manual for recommendations.
