Subaru Impreza Suspension Strut Mount Guide for 2002-2008 Models
Fixing the clunks, pops, and poor handling in your GD/GG Impreza starts right here.
- The most common sign of failure is a clunking or popping noise over bumps and when turning.
- Always replace strut mounts in pairs and get a wheel alignment immediately afterward.
- KYB is the OEM-equivalent brand for a factory ride and longevity; other brands are a compromise.
- Due to a recall on control arms for rust, carefully inspect the entire suspension area for corrosion during repair.
Is Your Impreza's Strut Mount Failing?
A failing strut mount on a 2002-2008 Impreza isn't just annoying—it's a sign that your suspension needs attention. Because this part is made of rubber and contains a bearing, it wears out over time. Here are the most common signs that it's time for a replacement.
🎬 Watch: 5 common symptoms of a bad strut mountClunking and Popping Noises
This is the most frequent complaint. You'll hear a distinct clunk, pop, or knocking sound from a corner of the car, especially at low speeds over bumps, driveways, or uneven pavement. A popping or creaking noise when you turn the steering wheel while parked or moving slowly also points directly to a worn strut mount bearing.
Poor Handling and Steering Response
A bad mount can make your steering feel vague, jerky, or 'notchy' when turning. The car might feel less stable in corners or pull to one side. This is because a worn mount allows for excessive movement at the top of the strut, which changes the suspension geometry and compromises control.
Vibrations
If you feel more vibration through the steering wheel or the floor of the car, the rubber in the mount may have hardened or collapsed. It's no longer doing its job of isolating the car's body from road harshness.
A Note on Rust: Check Your Control Arms
While there are no recalls for the strut mounts themselves, many 2002-2007 Imprezas were recalled in salt-belt states for severe rust on the front lower control arms (NHTSA Recall #11V-464). This shows these cars are prone to suspension corrosion. When you inspect your strut mounts, take a close look at the strut towers, the strut body itself, and the lower control arms for any signs of serious rust.
Choosing the Right Aftermarket Strut Mount
Not all aftermarket parts are created equal. For your Impreza, the brands available generally fall into three quality tiers. Always replace strut mounts in pairs (both front or both rear) to ensure balanced handling.
Tier 1: OEM-Equivalent
KYB: KYB is the original equipment manufacturer for Subaru's suspension components. Choosing a KYB strut mount is the closest you can get to buying the part from a Subaru dealer. It will provide the ride quality and lifespan your car was designed to have. For reliability and a perfect fit, KYB is the top recommendation among owners and mechanics.
Tier 2: Standard Aftermarket
Monroe: Monroe is a well-known brand that often provides a softer, more comfort-oriented ride. While generally considered a decent replacement, forum discussions suggest their parts may not last as long as KYB and are a step down in overall quality. They are a functional choice if OEM performance isn't a priority.
Beck Arnley: This brand sources parts from various manufacturers, sometimes even re-packaging the OEM part. The quality can be excellent, but it can also be inconsistent. It's a viable option, but KYB offers more certainty.
Tier 3: Economy Brands
DEA and Westar: These brands are typically found in the 'economy' section. While the price is low, the quality and longevity can be a gamble. They might be suitable for a short-term fix or a vehicle that isn't driven hard, but for the Impreza's suspension, investing in a higher-tier part is usually worth it to avoid doing the job twice.
Pro Tip: Get an Alignment!
Replacing a front strut mount will change your suspension angles. You must get a professional four-wheel alignment immediately after the repair. Skipping this step will cause the car to handle poorly and will destroy your tires in a very short amount of time.

Frequently Asked Questions
Do I have to replace strut mounts in pairs?
Yes, absolutely. Suspension components should always be replaced in pairs (both front or both rear) to ensure the car's handling is even and predictable. Replacing only one side can lead to unstable driving characteristics.
Is a wheel alignment really necessary after replacement?
Yes, it is mandatory. The strut mount is a key part of your suspension geometry. Replacing it will alter your alignment settings. Driving without a proper alignment will cause rapid and uneven tire wear, poor handling, and a crooked steering wheel.
Can I replace just the mount, or should I get a whole new strut assembly?
You can replace just the mount, but it requires a dangerous tool called a spring compressor to disassemble the strut. For safety and ease, many DIYers and shops prefer using a 'quick strut' or complete strut assembly, which includes a new strut, spring, and mount 🎬 Watch this step-by-step Subaru front shock and mount replacement all in one unit. This is a great option if your struts are also old and worn.
Why is the front mount different from the rear?
The front strut mount contains a bearing that allows it to pivot with the steering. The rear mount is typically a solid rubber and metal piece, as the rear wheels do not steer. 🎬 See how to fix clunking noises in the rear suspension This is why front mounts are often the first to fail and cause noise when turning.
