A common issue for this generation of Buick Regal is a clunking or thumping noise from the front suspension, especially when the suspension extends after hitting a pothole. A General Motors Technical Service Bulletin (TSB #12-03-08-001) points to leaking fluid from the original struts as the cause. This oil contaminates the jounce bumper, causing it to slam against the upper spring seat, creating the noise. If you hear this sound, inspect your front struts for any signs of oil leakage. While there are no specific recalls for the front struts, a recall was issued for rear suspension toe links on 2012-2013 models in certain states due to corrosion concerns.
Symptoms of a Failing Strut Assembly
Watch for these common signs that your Regal's struts need attention:
- Bouncy or Unstable Ride: The vehicle bounces excessively after hitting bumps and feels less stable on the road.
- Clunking or Knocking Noises: You may hear clunking, rattling, or popping sounds when driving over bumps or turning. This is a primary symptom noted in service bulletins. 🎬 See a breakdown of the top 7 failing strut symptoms
- Nose-Diving When Braking: The front of the car dips down significantly when you apply the brakes.
- Uneven Tire Wear: Worn struts can cause the inside or outside edges of your tires to wear down prematurely.
- Visible Fluid Leaks: Oily residue on the strut body is a clear sign the internal seal has failed.
Choosing the Right Aftermarket Strut Assembly
Replacing the entire strut and coil spring assembly (often called a "quick strut" or "loaded strut") is highly recommended. It's safer and easier than disassembling the old unit to reuse the spring. Aftermarket brands offer a range of options to fit your budget and performance needs.
Aftermarket Brand Tiers for Buick Regal
| Brand Tier | Brands | Description |
|---|---|---|
| Premium / OE-Equivalent | KYB | KYB is a well-regarded OEM supplier for many manufacturers. Their Excel-G line is designed to restore the vehicle's original handling and performance. Many mechanics and owners prefer KYB for its durability and ride quality that is often slightly firmer than stock. |
| Mid-Grade / Standard Replacement | Monroe | Monroe is another major brand, known for its OESpectrum and Quick-Strut lines. They are often considered to provide a comfortable, sometimes softer-than-original ride. They are a reliable choice for daily driving and restoring factory comfort. |

Frequently Asked Questions
Do I have to replace the whole assembly or can I just replace the strut?
While you can replace just the strut cartridge, it requires a special spring compressor tool and is dangerous if done incorrectly. A complete assembly is safer, faster to install, and ensures all related components (mount, bearing, boot, spring) are new.
Will new struts restore my Regal's original ride height?
Yes, new coil springs included in a complete assembly are designed to restore the vehicle to its factory ride height, which may have sagged over time with the old springs. Some economy brands have been reported to alter ride height incorrectly, so choosing a quality brand is important.
What's the difference between KYB and Monroe for my Regal?
Generally, KYB struts are known for being slightly firmer, aiming to restore the original, new-car handling. Monroe struts are often perceived as being slightly softer, prioritizing a comfortable ride. Both are considered quality replacements.
Do I need a wheel alignment after replacing my front struts?
Yes, absolutely. Replacing the front struts changes the suspension geometry. A four-wheel alignment is necessary to correct the camber, caster, and toe angles to prevent uneven tire wear and ensure proper handling.
