Suspension Stabilizer Bar Bushing Kit Guide for the 1992-1993 GMC Typhoon
Eliminate suspension clunks and restore the sharp handling your high-performance SUV was built for.
- The primary symptom of failure is a clunking noise from the front suspension over bumps.
- You must choose between softer, quieter rubber bushings or firmer, higher-performance polyurethane bushings from a brand like Energy Suspension.
- The front stabilizer bar on the 1992-1993 Typhoon is 32mm (1.25 inches); you must buy the correct size bushing for it to fit.
- Replacement is a simple DIY job that can significantly restore handling and eliminate noise.
Is Your Typhoon Making Clunking Noises?
The 1992-1993 GMC Typhoon is a special, high-performance machine. Its all-wheel-drive system and sport suspension were designed for sharp handling. When the stabilizer bar bushings wear out, that precision is lost. The most common sign of failure is a clunking, rattling, or thumping sound from the front suspension, especially when driving over bumps, speed bumps, or uneven roads. You might also notice the sound when turning at low speeds.
Worn bushings allow the heavy steel stabilizer bar to move and knock against the vehicle's frame, creating noise and degrading handling. Ignoring this can lead to other issues like poor steering response and excessive body lean in turns, making your Typhoon feel less stable and predictable.
Choosing the Right Aftermarket Bushing Kit
Original factory bushings on the Typhoon were made of a soft rubber designed for a balance of comfort and performance. After 30 years, this original rubber is almost certainly cracked, hardened, or worn out. When choosing a replacement, your main decision is between new rubber bushings or upgrading to polyurethane.
Performance Upgrade: Polyurethane Bushings
For owners who prioritize handling and durability, polyurethane is the clear winner. These bushings are much firmer than rubber, which significantly reduces stabilizer bar deflection and sharpens steering response.
- Energy Suspension: This is the most well-known brand for polyurethane suspension parts. They offer a specific kit for the 1992-1993 Typhoon's 32mm (1.25 inch) front sway bar. This material resists wear from road grime, oils, and age far better than rubber. The trade-off can be a slight increase in ride harshness or noise (NVH). Proper lubrication with the included silicone grease during installation is critical to prevent squeaking.
Standard Replacement: Rubber Bushings
If you want to maintain the original ride quality and keep costs down, a new set of rubber bushings is a good choice. They provide better noise and vibration damping than polyurethane but will not last as long.
- Premium Brands (Moog, Delphi): Generally considered top-tier aftermarket parts, Moog and Delphi offer replacements designed to meet or exceed original equipment quality. Moog is a well-respected name in suspension, and Delphi is known for making parts to OE standards. These are excellent choices for a reliable, quiet, factory-feel repair.
- Economy Brands (Dorman, Mevotech, QuickSteer): These brands offer a cost-effective solution for getting the job done. While perfectly adequate for daily driving, they may not offer the same longevity or precise fit as the premium brands. For a rare, high-performance vehicle like the Typhoon, investing in a premium or performance part is often recommended.

Frequently Asked Questions
Will polyurethane bushings make my Typhoon's ride too harsh?
Polyurethane is stiffer than rubber, which can transmit more road vibration. However, for the stabilizer bar application, most drivers find the trade-off acceptable for the significant improvement in handling response and durability. The increased harshness is typically minimal compared to replacing other suspension components like control arm bushings with polyurethane.
How do I stop polyurethane bushings from squeaking?
Squeaking is the most common complaint with polyurethane bushings, and it's caused by a lack of lubrication. It is essential to liberally apply the supplied silicone-based grease to all surfaces of the bushing that will make contact with the stabilizer bar or the mounting bracket during installation. Petroleum-based grease should not be used as it can degrade the material.
Can I replace just the bushings, or do I need to replace the whole bar?
In almost all cases, you only need to replace the bushings. The stabilizer bar itself is a solid piece of steel and does not wear out unless it has been bent in an accident or is severely corroded. Replacing the worn bushings will restore its function.
Is this a difficult job to do at home?
No, this is considered a DIY-friendly job for someone with basic hand tools. The process involves safely lifting and supporting the front of the vehicle, removing two bolts on each bushing bracket, swapping the bushings, and re-installing the brackets. No special tools are typically required.
