A Guide to Engine Mounts for the 1999-2005 Mitsubishi Galant
Stop the shaking and clunking noises by understanding which engine mount you need for your Galant.
- The most common symptom is heavy vibration at idle while in gear, which may disappear in Park or Neutral.
- The front center mount is the most common one to fail; inspect it first.
- OEM mounts offer the best performance and longevity; budget aftermarket brands like Anchor or DEA often fail quickly and may not fix the vibration.
- Ensure you are buying the correct mounts for your engine (2.4L 4-Cylinder vs. 3.0L V6).
Is Your Galant Shaking or Making Clunking Noises?
When an engine mount fails on a 1999-2005 Mitsubishi Galant, the signs are hard to ignore. The rubber in the mount cracks and separates, or the hydraulic fluid in some mounts leaks out. This allows the engine to move and shake more than it should. The most common mount to fail on this generation of Galant is the front center mount, which can then cause others to wear out faster.
Common Symptoms of a Bad Mount:
- Excessive Vibration: You'll feel a strong vibration in the steering wheel and through the cabin, especially when the car is stopped at a light and in gear. For many Galants, this vibration might go away when you shift into Neutral or Park.
- Loud Noises: A distinct "clunk" or "thud" from the engine bay when you accelerate, brake, or shift from Park to Drive or Reverse is a classic sign. This is the sound of the engine moving and hitting its limits.
- Visible Engine Movement: Open the hood and have a helper shift the car from Park to Reverse and then to Drive (with their foot firmly on the brake). If you see the engine lurch or jump more than an inch or two, the mounts are likely bad.
Known Issues for This Vehicle
No recalls or Technical Service Bulletins (TSBs) have been issued by the NHTSA specifically for the engine mounts on the 1999-2005 Mitsubishi Galant. However, owner communities report that the front center engine mount is the most common failure point. It's wise to inspect this mount first if you suspect a problem.
Choosing the Right Aftermarket Engine Mount
When shopping for new engine mounts, you have a choice between OEM (Original Equipment Manufacturer) and various aftermarket brands. For the Galant, there is a noticeable difference in quality and longevity.
OEM vs. Aftermarket:
Genuine Mitsubishi mounts are widely considered to be the best quality, using rubber compounds that effectively absorb vibration and last for many years. Aftermarket mounts are much cheaper, but many owners report they are made with harder rubber that doesn't control vibration as well and can fail in as little as a few months. If your budget allows, OEM is the most reliable choice. If you choose aftermarket, be aware that you may be sacrificing smoothness and longevity.
Aftermarket Brand Tiers:
- Better Quality (but with mixed reviews): Beck Arnley is often positioned as a higher-quality aftermarket option that aims to match OEM specifications for imported vehicles like your Mitsubishi. However, some owners have experienced premature failures and fitment issues, making them a bit of a gamble.
- Economy Brands: Brands like Anchor, DEA, and Westar are widely available and very affordable. Unfortunately, they are frequently criticized in owner forums for poor quality, a short service life, and not solving the vibration issues. These are best considered a temporary or budget-focused fix.
Pro Tip: Your Galant has different mounts for the 2.4L 4-cylinder and 3.0L V6 engines. Always confirm the part fits your specific engine 🎬 Watch a helpful guide on replacing the transmission-side motor mount. before ordering. Many retailers sell complete kits that include all four mounts for your engine type, which can be a cost-effective way to do the job right.

Frequently Asked Questions
Can I replace just the one broken mount?
Yes, you can replace only the failed mount. However, mounts tend to wear at a similar rate. If one has failed, the others are likely worn and under extra strain. Replacing them as a set is often the best long-term strategy to ensure a smooth ride and prevent having to do the job again soon.
Is it hard to replace Galant engine mounts myself?
It is a moderately difficult job that is possible for a DIY mechanic. 🎬 Watch this step-by-step walkthrough of a Galant motor mount replacement. It requires safely supporting the engine from below with a jack and a block of wood. Some mounts are in tight spaces, especially the rear one, and may require removing other components like the battery tray or air intake box 🎬 See how to access and replace the difficult rear engine mount. for access.
What's the difference between a solid and hydraulic mount?
Solid mounts are made of solid rubber, while hydraulic mounts are filled with fluid. The fluid helps to better dampen engine vibrations at different speeds. Your Galant may have come with hydraulic mounts in certain positions from the factory. Cheaper aftermarket replacements are often solid rubber, which can lead to more noticeable vibration in the cabin compared to the original hydraulic design.
Will a bad engine mount cause my check engine light to come on?
It is very unlikely that a bad engine mount itself will trigger a check engine light. The light indicates a problem with the engine's performance or emissions system. However, extreme engine movement from a completely failed mount could potentially damage a sensor or wire, which could then cause the light to come on.
