Is Your Buick Century Making Noise Over Bumps?
If you're hearing clunks, feeling vibrations, or your steering feels loose, the control arm bushings on your 1997-2005 Buick Century may be worn out. These rubber parts take a lot of abuse over the years and eventually crack, tear, or get soft. When they fail, the control arm can move around too much, causing noticeable problems with your ride quality and handling.
Pro Tip: Replace the Whole Control Arm, Not Just the Bushing
For a vehicle like the 1997-2005 Buick Century, it is almost always better to replace the entire control arm assembly rather than trying to press out old bushings and press in new ones. The new arm comes with new bushings and a new ball joint already installed. This saves a huge amount of labor and eliminates the need for a special hydraulic press, making the job much easier for both DIY mechanics and professionals. While the part cost is higher, the total job cost is often very similar and you get the benefit of a new ball joint as well.
Symptoms of Bad Control Arm Bushings
- Clunking or Knocking Sounds: This is the most common sign. You'll hear it from the front suspension when you drive over bumps, potholes, or even during sharp turns.
- Steering Wander: The car may pull to one side, forcing you to constantly correct the steering wheel to drive straight.
- Vibrations: You might feel vibrations through the steering wheel, especially as you accelerate. The shaking can get worse as the bushings deteriorate.
- Uneven Tire Wear: Worn bushings throw off the wheel alignment, which can cause the inside or outside edge of your front tires to wear out faster than normal.
- Unstable Braking: In some cases, the vehicle may pull to one side when you apply the brakes firmly.
Choosing the Right Aftermarket Bushing Brand
For the Buick Century, you have several good aftermarket options. They generally fall into a few quality tiers. Since replacing the entire control arm is recommended, brand choice often applies to the complete assembly.
Premium Brands (OEM Quality or Better)
- ACDelco (Gold / Professional): As GM's own parts division, the ACDelco Professional line is considered an OEM-equivalent, high-quality part. This is a trusted choice for fit and durability. Avoid the lower-tier "Advantage" line if you want maximum longevity.
- Moog: Historically a top-tier aftermarket brand known for problem-solving designs. However, some forum users note that quality can be inconsistent in recent years, so it's wise to inspect the part on arrival.
- Delphi: Widely regarded as a premium brand that produces high-quality suspension components.
Standard / Value Brands
- Mevotech (Supreme): Mevotech's "Supreme" line is a strong mid-grade option that balances cost and quality.
- Dorman: Dorman offers a cost-effective solution and is a popular choice for budget-conscious repairs. Quality can be variable but is generally suitable for daily driving.
- QuickSteer: This is a standard replacement brand that offers a functional part at a lower price point.

Frequently Asked Questions
Should I replace just the bushings or the whole control arm?
You should replace the entire control arm assembly. The labor to press out the old bushings is intensive and requires special tools. A new control arm includes new bushings and a new ball joint, which is likely worn as well. This makes the job faster, easier, and provides better long-term value.
Do I need a wheel alignment after replacing control arm bushings?
Yes, absolutely. The control arm is a critical part of your suspension's geometry. Replacing it will alter your alignment settings. You must get a professional four-wheel alignment after the repair to ensure proper handling and prevent rapid tire wear.
Should I replace bushings on both sides at the same time?
Yes, it is highly recommended. Suspension components wear out at similar rates. If the bushing on one side has failed, the other side is likely not far behind. Replacing them in pairs ensures balanced handling and saves you from having to do the same job again soon.
What are OEM parts for my Buick Century?
The Original Equipment Manufacturer (OEM) parts for your Buick were made by or for General Motors. The closest you can get today is typically the "ACDelco GM Original Equipment" line. However, for an older vehicle, a quality aftermarket brand like ACDelco Professional, Moog, or Delphi often provides similar performance for a better price.
