Infiniti G5 Front Suspension Parts: What You Need to Know

If you're searching for Infiniti G5 front suspension parts, you may have noticed that there is no Infiniti model officially called the G5. This is almost certainly a common misspelling or shorthand for the Infiniti G35 (or possibly the G25). The Infiniti G35, produced from 2003 to 2007, is a popular sports sedan and coupe, and its front suspension system is a critical area for maintenance and upgrades. This guide covers the key front suspension components, signs they need replacement, and how to choose the right parts for your Infiniti G35 (or G25) to keep your ride smooth and safe.

Understanding Your Infiniti G35 Front Suspension

The front suspension on the Infiniti G35 (and the related G25) uses a multi-link setup with MacPherson struts. This design offers a balance of ride comfort and handling precision. Key components include:

• Strut assembly: Combines the shock absorber and coil spring into a single unit.
• Control arms: Upper and lower arms that connect the wheel hub to the chassis.
• Sway bar links: Connect the sway bar to the control arm to reduce body roll.
• Tie rods: Connect the steering rack to the steering knuckle.
• Ball joints: Pivot points between control arms and knuckle.
• Stabilizer bar bushings: Mount the sway bar to the frame.

All these parts wear over time and may need replacement, especially on higher-mileage vehicles.

Signs Your Front Suspension Needs Attention

• Clunking or knocking noises when going over bumps or turning.
• Excessive tire wear (feathering, cupping, or uneven edges).
• Loose or vague steering with play in the wheel.
• Vehicle pulls to one side during driving or braking.
• Bouncy ride or bottoming out over dips.

If you notice any of these symptoms, inspect the suspension components or have a mechanic do a thorough check.

Types of Front Suspension Parts

OEM (Original Equipment Manufacturer) Parts

OEM parts are made by the same suppliers that provided parts for the factory assembly. They offer exact fit, reliable performance, and a warranty. For the G35, OEM parts come from Nissan/Infiniti. They are the most expensive but guarantee compatibility and longevity.

Aftermarket Standard Parts

Aftermarket parts from brands like Monroe, Moog, KYB, and AC Delco are widely used. They are generally less expensive than OEM while meeting or exceeding original specifications. Many are designed to be direct replacements. For example, Monroe struts and Moog control arms are popular choices for the G35.

Performance/Upgraded Parts

If you drive your G35 aggressively or track it, performance parts can improve handling. Upgraded sway bars, coilover kits (like BC Racing or Tein), adjustable control arms, and polyurethane bushings reduce body roll and provide sharper steering response. However, they may sacrifice ride comfort and be overkill for daily driving.

Common Front Suspension Parts for Infiniti G35

Struts and Coil Springs

Worn struts lead to poor damping and increased stopping distances. Complete strut assemblies (quick-struts) include the strut, spring, and mount – making replacement easier. Recommended brands: KYB (OEM supplier for G35), Monroe, and Bilstein for performance. If you prefer to keep the original springs, buying just the strut cartridge is also possible.

Control Arms

Upper and lower control arms have bushings and ball joints that wear. Aftermarket arms often come with pre-installed bushings and ball joints, saving labor. Moog’s problem-solving line offers greasable ball joints for longer life.

Sway Bar Links

These are cheap and easy to replace. They commonly wear and cause clunking. Brands like Moog, Duralast, and Mevotech offer durable options. Polyurethane bushings for the sway bar mounts further improve stability.

Tie Rod Ends

Inner and outer tie rods connect the steering rack to the wheels. Loose tie rods cause steering play and misalignment. Replace in pairs (inner + outer together) and get an alignment afterward.

How to Choose the Right Parts

1. Confirm your exact model year and trim – The G35 went through changes in 2005 (new headlights, interior, and suspension tuning). Parts for 2003-2004 may differ from 2005-2007. Use your VIN to verify.
2. Decide on quality level – OEM for worry-free fit; premium aftermarket (KYB, Moog) for a strong balance of cost and quality; budget parts may save money upfront but often fail sooner.
3. Consider your driving style – Daily commuters can stick with standard replacement; enthusiasts might want performance upgrades.
4. Always replace in pairs – Replace both front struts at the same time to maintain even handling. Same for tie rods, control arms, and sway bar links.
5. Get a professional alignment – After any suspension work, a four-wheel alignment is necessary to prevent tire wear and ensure straight tracking.

Practical Buying Tips

• Check part numbers – Use an online catalog from a trusted retailer (like RockAuto or parts stores) by entering your vehicle details.
• Look for kits – Some brands sell front suspension kits that include multiple components (struts, mounts, sway bar links) at a discount.
• Avoid “cheapest” parts – Extremely low-priced parts often use inferior materials that wear quickly.
• Read product descriptions carefully – Ensure the part is direct fit (not universal) and includes necessary hardware.

Safety Considerations

Suspension parts are safety-critical. Never compromise on quality for brakes, steering, or suspension components. If you are not experienced with suspension work, have a certified mechanic install the parts. Improper installation can lead to loss of vehicle control.

Final Recommendation

For most Infiniti G35 (or G25) owners, the best approach is to use high-quality aftermarket parts from established brands like KYB for struts and Moog for control arms and links. These offer OEM-like fit and durability at a lower price point. If your car has over 100,000 miles, consider replacing the entire front strut assembly, sway bar links, and tie rod ends together – this restores the suspension to like-new condition. For track use, invest in coilovers and adjustable arms. Always verify that parts are correct for your specific model year, and don't forget an alignment after the job is complete.

By knowing the components and your options, you can confidently select Infiniti G5 front suspension parts that will keep your car handling as it should for years to come.
