A Practical Guide to Suspension Strut Mounts for the 1990-1994 Mitsubishi Eclipse
If you're hearing clunks and rattles from your 1G Eclipse suspension, your strut mounts might be the cause.
- The most common symptom of failure is a clunking noise over bumps.
- For this vehicle, KYB is the most recommended aftermarket brand for quality and reliability.
- This is not a beginner-friendly DIY job due to the need for a spring compressor; professional installation is recommended.
- Always replace mounts in pairs and get a wheel alignment immediately after the repair to prevent tire damage.
Is Your Eclipse Making a Clunking Noise?
A common sign of a worn-out strut mount on a first-generation Eclipse is a distinct clunking or knocking sound, especially when driving over bumps, potholes, or uneven pavement. This noise happens when the rubber inside the mount has deteriorated, allowing metal parts to hit each other. You might also notice a creaking or grinding sound when turning the steering wheel at low speeds, which points to a failed bearing in the front mount.
Choosing the Right Aftermarket Strut Mount
For a vehicle like the 1990-1994 Eclipse, finding original Mitsubishi (OEM) parts is difficult and often not necessary. The aftermarket provides several good options that meet or exceed original quality. Since labor is the most expensive part of this repair, choosing a quality mount is important to avoid doing the job twice.
| Tier | Brands | Description for a 1990-1994 Eclipse |
|---|---|---|
| Premium Aftermarket | KYB | KYB is a Japanese company known for being an Original Equipment Manufacturer (OEM) for many car brands. Their parts are designed to restore the car's original handling and ride quality. In communities for Eclipse owners, KYB is the most frequently recommended brand for struts and mounts, making it the safest bet for quality and longevity. |
| Mid-Grade Aftermarket | Mevotech | Mevotech is known for engineering parts that sometimes aim to improve on the original design. They offer a wide range of parts that fit many vehicles. While generally considered a decent mid-grade option, quality can sometimes be inconsistent compared to premium brands. |
| Economy Aftermarket | DEA | DEA is a budget-focused brand. These parts will fit and function, but their primary advantage is their low price. For a component that requires significant labor to replace, a budget part may not be the most cost-effective choice in the long run if it wears out prematurely. |
Estimated Replacement Costs
The part itself is not expensive, but the labor to install it is where the real cost lies. The mechanic has to remove the entire strut assembly to get to the mount.
| Part/Service | Estimated Cost Range |
|---|---|
| New Aftermarket Mount Kit | $14 - $25 |
| Shop Labor (per side) | $150 - $300 |
| Wheel Alignment (Required) | $100 - $150 |
| Total (per side, professional) | $264 - $475 |
Pro Tip: Replace in Pairs
It is highly recommended to replace strut mounts in pairs (both front or both rear). If one has failed, the other is likely not far behind. More importantly, always replace the mounts whenever you are replacing the struts. The labor is nearly identical, so you will save a lot of money by doing both jobs at once.
Frequently Asked Questions (FAQ)
Is replacing a strut mount a good DIY job?
This is a difficult and potentially dangerous job for a beginner. It requires removing the entire strut and spring assembly. You must use a special tool called a spring compressor to safely remove the spring. If this tool is used incorrectly, the compressed spring can release with enormous force, causing serious injury. This job is best left to an experienced mechanic.
Do I need a wheel alignment after replacing strut mounts?
Yes, a four-wheel alignment is necessary after replacing front strut mounts. The mounts are a key part of your suspension geometry, and replacing them will alter your car's alignment settings. Skipping the alignment will cause crooked steering, poor handling, and rapid, uneven tire wear.
Can I replace just one strut mount?
While you technically can, it is not recommended. Suspension components wear at similar rates. If the mount on one side has failed due to age and mileage, the other side is likely worn as well. Replacing them in pairs ensures balanced handling and prevents you from having to do the same job again on the other side a short time later.
Are there any recalls for the 1990-1994 Eclipse strut mounts?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from the NHTSA for suspension strut mounts on the 1990-1994 Mitsubishi Eclipse. There was a recall for a lower ball joint on some later models, but this is a different part.
