Hearing clunks and pops from your Legacy's suspension? It might be time for new strut mounts.
- The most common sign of failure is a clunking noise over bumps.
- For best results, choose KYB brand mounts, as they are often the original equipment supplier for Subaru.
- Always replace strut mounts in pairs and get a wheel alignment immediately after the repair.
- This is a complex repair requiring special tools; professional installation is strongly recommended for safety.
Is My Legacy's Strut Mount Failing?
A bad strut mount on a 1990-2000 Subaru Legacy will make its presence known. These cars are old enough that the original rubber is likely worn out. The most common complaint from owners is a distinct "clunking" or "popping" noise from the front end, especially when going over bumps, potholes, or making slow-speed turns in a parking lot. 🎬 Watch this guide on identifying common bad strut mount symptoms. You might also feel excessive vibration through the steering wheel or notice that your steering doesn't feel as responsive as it used to.
Choosing the Right Aftermarket Strut Mount
When replacing parts on an older Legacy, you have options. You don't need to pay dealership prices for an Original Equipment (OEM) part. Aftermarket brands offer a range of quality and price points that are a great fit for these vehicles.
Here's a breakdown of the brands available:
- Top Tier (OEM Quality): KYB is widely considered the best aftermarket choice for Subaru. In fact, KYB was the original manufacturer for many Subaru struts and suspension components. Choosing KYB means you're getting a part that is designed to match or exceed the original's performance and durability. Forum users consistently recommend KYB for fit and longevity.
- Mid-Grade (Reliable Value): Monroe is a well-known brand that offers a good balance of quality and price. Their mounts are generally considered to have a softer rubber than KYB, which might provide a slightly more comfortable ride but may not last as long. Some users have reported issues with KYB mounts being noisy and prefer Monroe, while others feel Monroe is a step down in quality from OEM. For a daily-driven Legacy, Monroe is a solid, affordable option.
- Economy (Budget-Focused): Brands like DEA and Westar fall into the budget category. While they are the most affordable, the quality of the rubber and bearings can be inconsistent. These are best suited for a car you're trying to get back on the road for minimal cost, but don't expect the same lifespan as a KYB or Monroe part.
Known Issues for 1990-2000 Subaru Legacy
Searches for official recalls or Technical Service Bulletins (TSBs) specifically for strut mount failure on the 1990-2000 Legacy came up empty. Most issues are related to normal wear and tear on these 25+ year old components. There was a recall for suspension rust on some 2000 models (NHTSA Campaign ID: 03V153000), but this concerned the rear subframe, not the strut mounts directly. The most common problems reported by owners in forums are simply age-related failures causing clunking noises.

Note: Costs are estimates and can vary based on your location, the specific parts chosen, and your mechanic's labor rates. It is highly recommended to replace strut mounts in pairs (both front or both rear).
Frequently Asked Questions
Can I replace just one strut mount?
It's not recommended. Suspension components should always be replaced in pairs (both front or both rear) to ensure even handling and predictable performance. If one side is worn out, the other side is likely not far behind.
Do I need an alignment after replacing strut mounts?
Yes, absolutely. Replacing the front strut mounts will affect your vehicle's suspension geometry. A four-wheel alignment is necessary to prevent uneven tire wear and ensure the vehicle handles correctly.
Is this a good DIY job?
This job is for experienced DIY mechanics only. It requires removing the entire strut assembly and using a spring compressor to safely remove the old mount. Spring compressors can be extremely dangerous if used incorrectly. If you are not 100% comfortable with this procedure, it is best left to a professional mechanic.

For a 1990-2000 Legacy, it's generally not necessary. Aftermarket brands like KYB offer OEM-equivalent quality, often for a lower price. Given the age of the vehicle, a high-quality aftermarket part is a very practical and effective choice.
