- Always replace stabilizer links in pairs to maintain balanced handling.
- For a heavy car like the Roadmaster, choosing a premium aftermarket brand like Moog or Delphi is a worthwhile investment for durability.
Is Your Roadmaster Making Noise Over Bumps?
One of the most common wear items on the 1990-1996 Buick Roadmaster is the front suspension stabilizer bar link. Because these cars are body-on-frame and heavy, the front suspension parts work hard. When a stabilizer link wears out, you'll know it. The first sign is almost always a clunking or rattling sound from the front end when you drive over bumps or uneven roads at low speeds.
Symptoms of a Failing Stabilizer Link
- Clunking or Knocking Sounds: A distinct metallic clunk or rattle from the front suspension when going over bumps, potholes, or even into a driveway. This is the most common symptom.
- Loose Steering or Body Roll: The car may feel less stable in turns, leaning or "swaying" more than usual. Your steering might feel a little loose or less responsive.
- Vibrations: In some cases, you might feel a slight vibration through the steering wheel.
Choosing the Right Aftermarket Link Kit
For a straightforward part like a stabilizer link, you don't necessarily need to buy an expensive OEM part from a dealer. The aftermarket offers a wide range of quality options. The original design is a simple bolt with bushings and spacers, which is easy for aftermarket companies to replicate and sometimes improve. Here’s a breakdown of the brands available.
Brand Tiers for Your Roadmaster
- Premium Brands (Moog, Delphi): These brands are often considered top-tier in the aftermarket. Moog, in particular, is known for its "Problem Solver" line, which may feature improvements like stronger bolts or more durable bushings. For a heavy car like the Roadmaster, a premium link kit can provide the longest life and best performance.
- Mid-Range & Value Brands (Dorman, Mevotech): These brands offer a good balance of price and quality. Dorman provides cost-effective replacements that are a popular choice for daily drivers. Mevotech offers several lines, from standard replacement to heavy-duty, and is generally seen as a solid value.
- Budget Brands (QuickSteer): Often a sub-brand of a larger company, these offer the lowest price. For a car that isn't driven hard or is on a tight budget, these can be a viable option, but they may not last as long as more expensive brands.
How Much Should It Cost?
Stabilizer bar links are one of the more affordable suspension repairs. The parts are inexpensive, and the labor is minimal. It's highly recommended to replace them in pairs to ensure balanced handling.

| Aftermarket Stabilizer Link Kit (Pair) | $10 - $65 |

Frequently Asked Questions
Should I replace stabilizer links in pairs?
Yes. It is always recommended to replace suspension components like stabilizer links in pairs (both front links at the same time). This ensures even wear and predictable handling. Since the other link has the same age and has been under the same stress, it is likely to fail soon anyway.
Is this a difficult DIY job?
No, this is a great job for a beginner. The replacement requires basic hand tools like wrenches and sockets. The process involves lifting the front of the car, removing the wheel, and undoing two nuts. The biggest challenge is often rust on the original nuts and bolts.
What happens if I don't replace a bad stabilizer link?
While a broken link won't stop you from driving the car, it is a safety issue. The clunking noise will get worse, and your vehicle's handling will be compromised, with significantly more body roll in turns. In an emergency maneuver, this lack of stability could make it harder to control the vehicle.
How can I be sure the clunking noise is the stabilizer link?
While the stabilizer link is the most common cause, other worn suspension parts can make similar noises. A mechanic can confirm the source of the noise quickly. A common way to check is to grab the link (with the car on the ground) and try to move it; if there is any play or it makes a noise, it needs to be replaced.
