Guide to Replacing the 1996-2004 Oldsmobile Bravada Stabilizer Bar Bushings
Eliminate that front-end clunking noise and restore your Bravada's handling with new sway bar bushings.
- The most common symptom of failure is a clunking or rattling noise from the front end over bumps.
- You must measure your sway bar's diameter before ordering to ensure you get the correct size bushing.
- Choose between softer rubber for an OEM ride or firmer polyurethane for enhanced performance.
- It is highly recommended to replace the sway bar end links at the same time for a complete suspension refresh.
Is Your Bravada Making a Clunking Noise?
The most common sign of worn stabilizer bar bushings on the 1996-2004 Oldsmobile Bravada is a distinct noise from the front suspension. Owners often describe it as a clunking, rattling, or knocking sound, especially when driving over bumps or on uneven roads. In fact, General Motors issued a Technical Service Bulletin (TSB) for related vehicles describing a "rattle noise in front suspension over small bumps, clunk or loose lumber type noise over uneven/wash board roads." You may also notice your SUV leans more in turns, feels less stable, or the steering feels a bit spongy.
A Note on Shared Platforms: Your 1996-2004 Oldsmobile Bravada shares its suspension and frame with the Chevrolet S-10 Blazer and GMC S-10 Jimmy. This means that stabilizer bar bushings and related information for those models are also a direct fit for your vehicle.
Choosing the Right Aftermarket Bushing Kit
When replacing your bushings, you have a choice between standard rubber and performance-oriented polyurethane. The original bushings are rubber, but high-quality aftermarket parts can be an upgrade.
Material: Rubber vs. Polyurethane
- Rubber Bushings: These provide a ride quality similar to the original factory parts. They are quiet and absorb vibrations well. Premium rubber or thermoplastic options from brands like Moog offer a great balance of comfort and durability.
- Polyurethane Bushings: This is a firmer, more durable material that holds the sway bar more securely. This can improve handling and make the vehicle feel more responsive in turns, similar to installing a larger sway bar. The main drawbacks are a potentially stiffer ride and the possibility of squeaking if they are not installed with the proper silicone-based grease.
Important: Measure Your Sway Bar! The 1996-2004 Bravada and its sister vehicles were offered with different sway bar diameters. Before ordering, you must measure the diameter of your vehicle's sway bar with a caliper to ensure you buy the correct size bushings.
Brand Tiers for Your Bravada
- Performance (Polyurethane): Brands like Energy Suspension and Nolathane specialize in polyurethane bushings. Choose these if you want to improve handling and get a sportier feel, but be prepared for a slightly firmer ride.
- Premium OEM-Style: Moog is a well-regarded brand known for its "Problem Solver" line, which often features design improvements over the original. Their thermoplastic bushings are an excellent choice for a durable, quiet ride that balances comfort and performance. Delphi is another brand that provides OEM-quality replacements.
- Standard Replacement: Brands like Mevotech, Dorman, and QuickSteer offer reliable, direct-fit replacements that will restore your vehicle's original handling and eliminate noise. They are a cost-effective solution for daily driving.
Pro Tip: Replace End Links at the Same Time. The stabilizer bar end links connect the ends of the sway bar to the control arms. They wear out just like the bushings and cause similar clunking noises. It is highly recommended to replace the end links when you replace the bushings for a complete repair.

Frequently Asked Questions
What is the main difference between rubber and polyurethane bushings?
Rubber bushings provide a softer, quieter ride like the original factory parts. Polyurethane bushings are stiffer and more durable, which improves handling and responsiveness but can make the ride feel firmer and may squeak if not greased properly.
Can I replace the stabilizer bar bushings myself?
Yes, this is a DIY-friendly job for someone with basic mechanical skills and tools. The process involves safely lifting the vehicle, unbolting the two brackets that hold the bushings, and swapping them out. The most common difficulty is dealing with rusted bolts.

While clunking can come from other worn parts like ball joints or end links, a noise that happens consistently over small bumps is a classic symptom of bad sway bar bushings. A visual inspection may reveal cracked, hardened, or deformed rubber around the sway bar where it mounts to the frame. A mechanic can use a pry bar to check for excessive movement.

No, replacing the stabilizer bar bushings or end links does not affect your vehicle's wheel alignment.
