1992-2001 GMC Yukon Suspension Stabilizer Bar Bushing Replacement Guide
Eliminate front-end clunks and restore handling by choosing the right stabilizer bar bushings for your Yukon.
- A clunking noise from the front end when going over bumps is the most common symptom of bad stabilizer bar bushings.
- You must measure your stabilizer bar's diameter before ordering to ensure you get the correct size.
- Choose rubber (Moog, Dorman) for a quiet, comfortable ride or polyurethane (Energy Suspension) for improved handling and durability.
- This is a simple DIY job, and it's a good idea to replace the sway bar end links at the same time.
Is Your Yukon Making a Clunking Noise?
If you're hearing a clunking, knocking, or rattling sound from the front of your 1992-2001 GMC Yukon, especially when going over bumps or turning, there's a good chance your stabilizer bar bushings are worn out. These parts are simple, but they are critical for a quiet and controlled ride. As they age, the original rubber hardens, cracks, or gets compressed, allowing the heavy metal stabilizer bar to move and knock against the frame.
Common Ordering Mistake
The most common mistake is ordering the wrong size. The 1992-2001 Yukon was available with different stabilizer bar diameters. Before ordering, you must measure the diameter of your stabilizer bar to ensure you get bushings that fit snugly. An easy way to do this is with an adjustable wrench: tighten it onto the bar, then measure the gap in the wrench with a tape measure or caliper.
Choosing the Right Aftermarket Bushings
You have a choice between standard rubber replacements and performance-oriented polyurethane bushings. Your driving style and priorities will determine the best option for your Yukon.
Brand & Material Tiers
- Economy (Standard Rubber): Brands like Dorman and QuickSteer offer affordable, direct-fit replacements. These are typically made of rubber, similar to the original equipment, and will restore a quiet, comfortable ride. They are a cost-effective solution for daily driving but may not last as long as higher-end options.
- OEM-Quality (Upgraded Rubber/Thermoplastic): Brands like Moog, Delphi, and Mevotech are known for quality that often meets or exceeds original specs. Moog, in particular, offers "Problem Solver" parts and thermoplastic bushings that are designed to be more durable than standard rubber without the harshness of polyurethane. These are an excellent all-around choice for longevity and a smooth ride.
- Performance (Polyurethane): Energy Suspension and Nolathane are the leaders in polyurethane bushings. Polyurethane is a much firmer material than rubber, which improves handling response and reduces body roll even further. It's also extremely durable and resistant to oil and heat. The downsides can be a harsher ride and the potential for squeaking if they are not installed with the special grease included in the kit. Many performance kits are also "greaseable," meaning they have a zerk fitting to allow for easy re-lubrication.
| Brand Tier | Brands | Material | Pros | Cons |
|---|---|---|---|---|
| Economy | Dorman, QuickSteer | Rubber | Affordable, quiet ride | May have shorter lifespan |
| OEM-Quality | Moog, Delphi, Mevotech | Rubber / Thermoplastic | Durable, excellent ride quality, trusted brands | Higher cost than economy |
| Performance | Energy Suspension, Nolathane | Polyurethane | Superior handling, maximum durability | Can cause a stiffer ride, may squeak if not greased |
Frequently Asked Questions
What's the difference between rubber and polyurethane bushings?
Rubber bushings provide a softer, quieter ride, similar to how your Yukon felt from the factory. They are excellent at absorbing vibrations. Polyurethane bushings are much stiffer, which provides better handling and a more connected feel to the road, but can transmit more vibration and noise into the cabin. Polyurethane is also more durable and resistant to chemicals and heat.
Should I replace the sway bar end links at the same time?
Yes, it's highly recommended. The sway bar end links connect the ends of the stabilizer bar to the lower control arms and have their own bushings that wear out. Since you'll already be working in the same area, replacing the end links along with the frame bushings ensures the entire stabilizer system is new 🎬 Watch this step-by-step guide to replacing your Yukon's bushings and links. and functioning correctly. Worn end links can also cause clunking noises.
Is replacing stabilizer bar bushings a difficult job?

It typically involves removing two bolts on each 🎬 See how easy it is to replace sway bar bushings yourself. bushing bracket, prying the old bushing off, and installing the new one. You do not need to remove the wheels, but it can make access easier. The most important part is safely lifting and supporting the vehicle with jack stands.
Are there any recalls or TSBs for my Yukon's stabilizer bushings?
No specific recalls were found for stabilizer bar bushings on the 1992-2001 GMC Yukon. However, on later model GM trucks and SUVs, a Technical Service Bulletin (TSB 15-NA-082) was issued for clunking noises caused by cracked stabilizer shaft frame brackets due to insufficient welds. While not directly applicable to the 1992-2001 generation, it's always a good idea to inspect the frame and brackets 🎬 Follow this video tutorial for replacing bushings on GMC trucks and SUVs. for cracks when you replace the bushings.
