Eliminate clunking noises and tighten up your Ascender's handling by replacing worn stabilizer bar bushings.

- Quality aftermarket brands like Moog or Delphi offer excellent performance and value compared to OEM parts.
- Always replace bushings in pairs (both front or both rear) to ensure balanced performance.
Is Your Ascender Making Clunking Noises?
If you're hearing a clunking, rattling, or knocking sound from the front or rear suspension, especially when driving over bumps or uneven roads, worn stabilizer bar bushings are a likely culprit. These sounds occur because the worn bushing allows the heavy metal stabilizer bar 🎬 Watch what a worn stabilizer bushing sounds like and how to replace it. to move and knock against the vehicle's frame. You might also notice that your Ascender feels less stable or has more body roll during turns. While worn bushings are not a critical safety failure, they make for a noisy and unpleasant ride and can put extra stress on other suspension components like the sway bar end links.
Don't Ignore the Noise
A clunking sound from your suspension is your vehicle telling you something is wrong. While bad stabilizer bushings are common, the noise can also indicate other issues like worn ball joints or bad sway bar end links. It's important to inspect the entire suspension to correctly identify the source of the problem 🎬 Learn how to inspect your sway bar bushings and end links..
Choosing the Right Aftermarket Bushing Kit
For the 2003-2008 Isuzu Ascender, which shares its platform (GMT360) with the Chevy Trailblazer and GMC Envoy, you have several good aftermarket options. There is little practical difference between OEM and quality aftermarket bushings for this application; aftermarket parts often meet or exceed original quality at a better price. The key is choosing a reputable brand.
Brand Tiers for Your Isuzu Ascender
- Premium Brands (Moog, Delphi): Moog is a well-regarded name in suspension parts, often praised for durability and including features like high-quality materials. Delphi is another top-tier supplier with a strong reputation. These brands are an excellent choice for owners who want a long-lasting, reliable repair.
- Quality Mid-Range (Mevotech, QuickSteer): Mevotech offers innovative designs and is often seen as a strong competitor to Moog 🎬 See a comparison between Mevotech and Moog suspension parts., sometimes at a more affordable price. They provide a good balance of quality and value. QuickSteer is another solid option in this category.
- Economy Brands (Dorman, various store brands): Dorman provides a wide range of parts that are typically the most budget-friendly. While perfectly functional, some users in forums report that their longevity might not match the premium brands. These are a good choice for a quick, low-cost repair.
Rubber vs. Polyurethane
Most aftermarket bushings are made from rubber or a thermoplastic material similar to the original. Some brands offer polyurethane bushings, which are stiffer and can improve handling response. However, polyurethane can sometimes cause squeaking noises if not lubricated properly during installation. For most Ascender owners, a quality rubber or thermoplastic bushing is the best all-around choice.

Frequently Asked Questions (FAQ)
Do I need to replace bushings in pairs?
Yes. It's recommended to replace both the driver and passenger side bushings for a given axle (front or rear) at the same time. They wear at a similar rate, and replacing them in pairs ensures balanced handling and prevents you from having to do the job again soon.
Is a special alignment needed after replacement?
No. Replacing the stabilizer bar bushings does not affect your Ascender's wheel alignment settings.
Can I replace just the bushings, or do I need the whole bar?
You only need to replace the bushings. The stabilizer bar itself is a durable steel component that rarely needs replacement unless it is bent or heavily corroded.
Are there any recalls for the Ascender's stabilizer bar bushings?
There are no specific recalls from the NHTSA for the stabilizer bar or its bushings on the 2003-2008 Isuzu Ascender. There was a recall for some Isuzu models concerning rear suspension link bracket corrosion in salt-belt states, but this did not apply to the Ascender.
