A Mechanic's Guide to the 2002-2007 GMC Yukon Stabilizer Bar Bushing Kit
Stop the front-end clunking and tighten up your Yukon's handling by choosing the right sway bar bushings.
- 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 with a caliper before ordering to ensure you get the correct size bushings.
- Polyurethane bushings from brands like Energy Suspension offer a performance upgrade, while rubber bushings from Moog or Delphi provide an OEM-like ride.
- This is a common wear item and a relatively simple, inexpensive DIY repair that can significantly improve your Yukon's handling and quiet the ride.
Is Your Yukon Making a Clunking Noise?
If you're hearing a clunk, rattle, or knocking sound from the front of your 2002-2007 Yukon, especially when going over bumps or turning at low speeds, there's a good chance your stabilizer bar bushings are worn out. These parts are made of rubber and simply wear down over time from age, heat, and constant movement. On a vehicle of this age, it's a very common repair item. Other signs include a loose or vague feeling in the steering, excessive body roll in corners, or a general feeling of instability.
Measure Before You Buy!
The single most common mistake when ordering this part is getting the wrong size. The 2002-2007 GMC Yukon was built with several different stabilizer bar diameters. You must measure the diameter of your vehicle's stabilizer bar with a caliper before ordering new bushings to ensure a correct fit. An incorrect size will either not fit or will fail very quickly.
Choosing the Right Aftermarket Bushings
For a vehicle of this age, aftermarket bushings offer excellent value and, in some cases, an upgrade over the original factory parts. The original rubber bushings were designed for comfort, but can wear out. Aftermarket options come in different materials and quality levels.
Material: Rubber vs. Polyurethane
- Rubber Bushings: These are the standard replacement type, similar to what your Yukon came with from the factory. They offer a quiet, comfortable ride and are a good choice for daily driving. Brands like Delphi, QuickSteer, and some Dorman or Mevotech kits fall into this category.
- Polyurethane Bushings: Often called "poly" bushings, these are a performance upgrade. They are much firmer and more durable than rubber. This results in a more responsive and planted feel, with less body roll. Brands like Energy Suspension and Nolathane specialize in polyurethane. The trade-off can be a slightly firmer ride and they must be installed with the supplied grease to prevent squeaking.
Brand Quality Tiers
While individual experiences vary, here's a general breakdown of the available brands based on owner and mechanic feedback.
- Premium / Performance (Polyurethane): Energy Suspension, Nolathane. These brands are highly recommended in forums for their durability and performance benefits. They are an excellent choice if you want to improve handling or if you tow and haul frequently.
- Premium (Rubber): Moog, Delphi. Moog is a well-known premium aftermarket brand often praised for quality and including all necessary hardware. Delphi is an original equipment supplier to many manufacturers and is considered a high-quality choice.
- Standard / Economy: Dorman, Mevotech, QuickSteer. These brands offer a cost-effective solution that meets or exceeds original specifications. They are a popular choice for a budget-friendly repair that restores original performance.

Pro Tip: Replacing the stabilizer bar bushings is a straightforward job that many DIY mechanics can perform at home in about an hour with basic hand tools. This can save you the cost of labor. It's also a good time to inspect the stabilizer bar end links, as they often wear out at the same time and are inexpensive to replace as a set.
Frequently Asked Questions
Do I need to replace the whole stabilizer bar?
No, in almost all cases you only need to replace the rubber or polyurethane bushings and possibly the end links. The metal stabilizer bar itself rarely fails unless it has been bent in an accident or is severely corroded.
What is the difference between rubber and polyurethane bushings?
Rubber bushings provide a softer, quieter ride similar to the original factory feel. Polyurethane bushings are firmer, more durable, and provide better handling performance by reducing body roll, but may transmit slightly more road feel. Polyurethane kits require proper lubrication during installation to prevent noise.
Are there any recalls or TSBs for this issue?
There are no specific recalls for the stabilizer bar bushings on the 2002-2007 GMC Yukon. However, a Technical Service Bulletin (TSB 24-NA-099) exists for a related issue where the weld nut for the stabilizer bar bracket bolt can break loose inside the frame, causing a clunking noise. If the bolt just spins when you try to loosen it, this may be the cause.
Should I replace bushings in pairs?
Yes, absolutely. Bushings are sold in kits for a reason. You should always replace the frame-mount bushings on both the driver and passenger sides at the same time to ensure even handling and performance.
