2010 Mitsubishi Galant Suspension Parts: A Complete Guide to Replacement and Upgrades

The 2010 Mitsubishi Galant is a midsize sedan known for its comfortable ride and solid reliability. However, after a decade or more on the road, its suspension system naturally begins to wear. Worn shocks, sagging springs, or loose control arms can lead to poor handling, uneven tire wear, and a noisy ride. Whether you are restoring a Galant to its original feel or looking for affordable replacements, understanding the specific suspension parts and their function will help you make smart buying decisions. This article covers the most common suspension issues for the 2010 Galant, explains the key parts, and provides practical guidance on choosing between OEM and aftermarket components.

Common Suspension Issues for the 2010 Galant

Owners of the 2010 Galant often report similar suspension problems as the vehicle ages. The most frequent issues include:

• Worn struts and shocks: After 80,000–100,000 miles, the damping performance decreases. You may notice excessive bouncing, nose dive during braking, or a floaty feeling at highway speeds.
• Failing sway bar links: These small links connect the sway bar to the control arm or strut. When they wear, you'll hear a clunking noise over bumps.
• Worn control arm bushings: The front lower control arms have bushings that deteriorate over time, causing vague steering and knocking sounds.
• Sagging rear springs: The rear coil springs can settle, leading to a lower ride height and reduced load capacity.
• Loose or worn tie rods: Inner and outer tie rod ends can develop play, creating steering wander and uneven tire wear.

Identifying these problems early can prevent more expensive repairs down the road. A simple visual inspection and a test drive usually reveal the worn components.

Key Suspension Parts Explained

To replace suspension parts correctly, you need to know what each component does and the specific fitment for the 2010 Galant. Below are the most commonly replaced parts, grouped by front and rear.

Struts and Shocks

The 2010 Galant uses front struts (a strut is a shock absorber integrated with a coil spring and bearing mount) and rear shocks (separate from the spring). For the front, you can buy a complete strut assembly (pre-loaded with spring and mount) or just the strut cartridge and reuse the old spring. For the rear, shocks are sold individually. KYB and Monroe are popular aftermarket brands offering both OEM-quality and upgraded options.

Control Arms

The Galant has front lower control arms that include ball joints. Many aftermarket arms come as a complete unit with bushings and ball joint pre-installed. Replacing the entire arm is often easier than pressing out bushings. Moog and AC Delco produce durable options that meet or exceed OEM specifications.

Sway Bar Links and Bushings

Sway bar links (also called stabilizer links) are inexpensive and quick to replace. If you hear a clunk from the front or rear when turning or going over bumps, these are likely the culprit. Moog problem solver links with grease fittings allow for future lubrication. Don't forget the sway bar bushings themselves—they can also wear and cause looseness.

Tie Rod Ends

Inner and outer tie rods are part of the steering linkage. Worn tie rods cause steering play and can lead to uneven tire wear. For the 2010 Galant, replacing the outer tie rod ends is common; the inners last longer but should be checked. Moog and TRW offer quality replacements.

Coil Springs

If your Galant sits lower than normal, especially in the rear, the coil springs may have sagged. Aftermarket springs from Moog or OEM replacements restore ride height. Avoid cheap generic springs as they may not handle the weight correctly.

Ball Joints

Ball joints in the front lower control arms are often part of the arm assembly. If you buy just the ball joint separately, ensure it is pressed in correctly. For DIYers, a complete control arm saves time.

OEM vs Aftermarket: What to Choose?

When ordering suspension parts for your 2010 Galant, you have three typical options: genuine Mitsubishi OEM parts, known aftermarket brands, and budget generic parts. Here is how they compare.

Genuine OEM Parts

Mitsubishi OEM parts are exact matches for the original components. They come with a manufacturer warranty and are designed to last as long as the originals. However, they are also the most expensive option. OEM is ideal if you want to keep the car completely stock and plan to own it for several more years.

Aftermarket Brands

Reputable aftermarket brands like KYB, Monroe, Moog, AC Delco, and TRW produce parts that often exceed OEM quality in some areas (e.g., grease fittings, corrosion resistance). These parts are usually priced 20–40% lower than OEM while offering similar or better durability. For most Galant owners, a quality aftermarket part is the best value.

Budget/Generic Parts

Unknown brands or ultra-cheap parts from online sellers often cut corners on materials and manufacturing tolerances. They may fit but can wear out prematurely, leading to noise, poor ride, or early failure. Avoid these unless you are on a very tight budget and plan to replace the car soon.

Recommended Brands for the 2010 Galant

Based on compatibility and owner feedback, these brands work well for the Galant suspension:

• Struts and shocks: KYB Excel-G (OEM replacement) or Monroe OESpectrum. For a firmer ride, KYB Gas-A-Just.
• Control arms: Moog (with greaseable ball joints) or AC Delco.
• Sway bar links: Moog Problem Solver.
• Tie rods: Moog or TRW.
• Coil springs: Moog CC series or original Mitsubishi.

When purchasing, check the year and engine size (2.4L or 3.8L) as some parts differ. Also, confirm if your Galant has the sport or base suspension – the sport tuned version may have different spring rates.

Practical Tips for Buying and Installation

• Buy complete strut assemblies for the front: they come with spring, mount, and bearing pre-installed, saving you the hassle of compressing the spring and pressing bearings. This is safer for DIYers.
• Replace in pairs: Always replace struts or shocks on both sides (front pair or rear pair) to maintain even handling.
• Get an alignment: After replacing any steering or suspension component (tie rods, control arms, struts), you must get a professional wheel alignment. Otherwise, tire wear and steering issues will persist.
• Torque to spec: Use a torque wrench for all fasteners. Loose or overtightened bolts can cause noise or damage. Common torque values for the Galant suspension are available in the service manual.
• Consider a complete kit: Some vendors sell suspension kits that include all four struts/shocks plus mounts and boots. These can save money and ensure everything matches.

Final Recommendation

For most owners of a 2010 Mitsubishi Galant, the smartest choice is to replace worn suspension parts with quality aftermarket components from KYB or Moog. They offer the best balance of durability, performance, and cost. If you value originality and plan to keep the car for many years, OEM is a safe but pricier route. Avoid generic no-name parts. Start by diagnosing which components are actually worn – a simple bounce test and inspection of bushings and links will point you in the right direction. Pair your replacement with a proper alignment, and your Galant will ride like new again.
