Nissan Elgrand E51 Suspension Parts: What You Need to Know

If you own a Nissan Elgrand E51, you know it's a versatile and spacious minivan. However, like any vehicle, its suspension system wears over time. Whether you're dealing with a rough ride, uneven tire wear, or knocking noises, understanding the suspension parts for the Elgrand E51 is essential for proper maintenance and upgrades. This guide covers the key components, common problems, and how to choose the right parts for your vehicle.

Understanding the Nissan Elgrand E51 Suspension System

The Nissan Elgrand E51 (2002–2010) features a front MacPherson strut suspension and a rear multi-link setup. This design prioritizes ride comfort and handling stability, but it also means several components are prone to wear. The suspension system includes struts, springs, control arms, sway bars, and bushings. Each part plays a role in absorbing road impacts, maintaining tire contact, and ensuring steering responsiveness.

Common Suspension Issues in the Elgrand E51

Owners frequently report a few recurring problems:

• Worn front struts: Leaking fluid or reduced damping cause a bouncy ride.
• Rear coil springs sagging: Especially on vehicles with heavy loads or higher mileage.
• Control arm bushings failing: This leads to clunking noises and vague steering.
• Sway bar link breakage: Results in body roll during cornering.
• Damper mounts cracking: Often overlooked but crucial for noise isolation.

Identifying these issues early can prevent secondary damage to tires and steering components.

Key Suspension Parts for the Nissan Elgrand E51

Front Struts and Shocks

The front suspension uses strut assemblies that combine a spring and shock absorber. When replacing, you can choose between complete strut assemblies (with new springs and mounts) or just the shock insert. For the Elgrand E51, OEM or high-quality aftermarket struts from brands like KYB or Monroe are popular choices. Ensure you match the part number to your specific model year and engine variant, as there may be differences between the 2.5L and 3.5L versions.

Rear Shocks

The rear uses separate shock absorbers. They are easier to replace than the front struts. Look for gas-charged shocks for better performance. If you carry heavy loads often, consider heavy-duty shocks that resist fade.

Coil Springs

Front and rear springs can sag over time. Upgraded springs (e.g., from King or Lovells) may raise the ride height slightly and improve load capacity. Be aware that aftermarket springs can alter ride comfort. For stock ride quality, OEM springs or equivalent are recommended.

Control Arms

The upper and lower control arms at the front have ball joints and bushings that wear. In many cases, it's more cost-effective to replace the entire arm rather than just the bushings, especially if the ball joint is loose. Aftermarket control arms with polyurethane bushings offer longer life but may transmit more road noise. OEM-style rubber bushings are quieter.

Sway Bar Links (Stabilizer Links)

These small links connect the sway bar to the control arms. They are prone to snapping or loosening. Replace them in pairs. Aftermarket links with grease fittings allow for periodic lubrication and longer life.

Bushings

Bushings in the lower control arms, trailing arms, and sway bar mounts can deteriorate. Polyurethane bushings are a popular upgrade for better handling, but they require more maintenance (greasing). Rubber bushings are quieter and require no upkeep but wear faster.

Other Components

• Strut mounts: Replace them when doing struts to avoid future noise.
• Coil spring insulators: These rubber pads prevent squeaking.
• Dust boots: Protect the shock rod; if torn, replace with new shocks.

OEM vs Aftermarket: Which to Choose?

For the Nissan Elgrand E51, OEM parts are made by Nissan and are guaranteed to fit perfectly. They are typically more expensive but offer predictable performance and durability. Aftermarket parts vary widely in quality. Reputable brands like KYB, Monroe, Moog, and Energy Suspension produce reliable components that match or exceed OEM specs. Budget brands may save money upfront but can fail prematurely.

When to choose OEM:

• If you want the exact original ride quality.
• For critical safety components like steering knuckles.
• When other parts are still in good condition and you only need one component.

When to choose aftermarket:

• For upgraded performance (e.g., polyurethane bushings).
• To save money on high-wear items like sway bar links.
• When OEM parts are backordered or discontinued.

Be cautious with cheap parts—they often lack proper quality control. Stick to known brands and double-check fitment for your Elgrand E51.

Tips for Purchasing Suspension Parts

1. Verify your VIN or model details: The Elgrand E51 has multiple sub-models (e.g., Highway Star, Lounge). Differences in suspension may exist. Cross-reference part numbers with your vehicle's specifications.
2. Buy in sets: Replace struts, shocks, and springs in pairs (both front or both rear) to maintain balanced handling.
3. Check for import compatibility: If you're in the US, your Elgrand was likely imported from Japan. Some parts may be specific to the Japanese market. Suppliers that specialize in JDM vehicles are a good resource.
4. Consider a complete overhaul: If your suspension is very worn, replacing all components at once saves labor costs and ensures consistency.
5. Look for warranty: Good aftermarket parts often come with a limited lifetime warranty, which adds peace of mind.

Final Recommendation

For most Nissan Elgrand E51 owners, the best approach is to use a mix of quality aftermarket parts for wear items (sway bar links, bushings) and OEM or equivalent for core components like struts and control arms. Brands like KYB Excel-G (shocks) and Moog (control arms) offer excellent value. Prioritize safety-critical parts and always replace in pairs. If you're not comfortable with DIY, have a shop experienced with JDM vehicles handle the installation. Addressing suspension issues promptly will keep your Elgrand driving smoothly and safely for years.
