2002-2013 Nissan Altima Suspension Struts: Clunks, Leaks, and Generation Mismatches

Key Differences: 2002-2006 vs. 2007-2013 Altima

The 2002-2013 year range for the Nissan Altima covers two distinct vehicle generations that use different suspension components. It is critical to identify the correct generation for your vehicle before purchasing parts.

• Third Generation (2002-2006): These models (platform code L31) have their own specific strut design. Parts for these years are not interchangeable with later models.
• Fourth Generation (2007-2013): This generation (platform code L32) has a major compatibility trap. The Sedan was produced from 2007-2012, while the Coupe continued on the same platform through 2013. A new generation of Altima Sedan (L33) was introduced for the 2013 model year.

Symptoms of a Failing Suspension Strut

Worn struts can cause a variety of problems, from annoying noises to unsafe driving conditions. Many owners report that struts on the Altima may begin to show signs of wear between 60,000 and 80,000 miles.

Noises

• Clunking or Knocking: This is the most common symptom. A sharp clunking or knocking sound when driving over bumps, potholes, or uneven pavement often points to worn struts or, more specifically, worn strut mounts.
• Squeaking or Creaking: A creaking or groaning noise, especially when turning the steering wheel at low speeds, can indicate a failing strut mount bearing or a dry ball joint.
• "Boinking" Sound: A "boink" or twang when turning the wheel can be a sign of a binding or broken coil spring, or a bad strut mount bearing.

Poor Ride and Handling

• Bouncy Ride: If the car continues to bounce up and down after hitting a bump, the strut's internal shock absorber has likely failed.
• Nose-Diving and Squatting: The front of the car dipping excessively during braking ("nose-dive") or the rear squatting during acceleration are classic signs of worn struts.
• Body Roll: Increased leaning or swaying when turning corners indicates the struts are no longer able to control the vehicle's body movements effectively.
• Vibrations: A new or excessive vibration felt in the steering wheel, especially at highway speeds, can be caused by worn suspension components, including the struts.

Visual Signs

• Fluid Leaks: Look for oily, wet patches on the body of the strut. This indicates that the hydraulic fluid has leaked out, and the strut can no longer dampen impacts.
• Uneven Tire Wear: Worn struts can cause wheel alignment to shift, leading to cupping (scalloped wear patterns) or bald spots on the tires.
• Damaged Strut Boot: A torn or missing rubber dust boot will allow dirt and moisture to damage the strut's seals, leading to premature failure.

Known Issues, TSBs, and Recalls

While no recalls directly target the struts themselves across the entire 2002-2013 range, several related issues are worth noting:

• NHTSA Campaign PC012 (2009-2010 Models): A voluntary safety recall was issued for some 2009-2010 Altima and Maxima vehicles due to front strut mounting insulators that were not manufactured to specification and could crack. The remedy was to replace the insulators.
• NHTSA Campaign 12V494000 (2012-2013 Models): A recall was issued for certain 2012-2013 Altimas because transverse link bolts and power steering rack bolts may not have been properly torqued, which could cause them to loosen.
• Rear Lower Control Arm Corrosion (2013 Models): The NHTSA investigated complaints of rear lower control arm failure due to corrosion on 2013 Altimas, particularly in states that use road salt. While this is a separate part, a failure here can be mistaken for a strut issue and represents a significant safety concern for the rear suspension.

Buying a Used Suspension Strut

A used OEM (Original Equipment Manufacturer) strut can be a smart purchase, often providing better performance and longevity than a new, low-quality aftermarket part. However, since struts are wear items, careful inspection is crucial.

Inspection Checklist

• Check for Leaks: The strut body should be dry. Any sign of oil or wetness means the internal seals have failed. Do not buy a leaking strut.
• Inspect the Rod: The chrome-plated piston rod extending from the top should be smooth, straight, and free of rust or pitting. Any damage to this surface will destroy the seals.
• Examine the Mount: If buying a complete assembly, inspect the top strut mount. The rubber should not be cracked, separated, or bulging. Push down on the mount; there should be minimal movement.
• Check the Coil Spring: Look for cracks in the paint or heavy rust, which can lead to the spring breaking. Ensure the spring is seated correctly in its perches.
• Mileage Consideration: Struts typically last 50,000 to 100,000 miles. A used strut from a low-mileage vehicle (under 70,000 miles) is ideal. Be wary of struts from high-mileage cars, as they may not have much life left.

Compatibility Verification

This is the most critical step. Double-check that the part is correct for your exact vehicle:

1. Vehicle Year and Model: Confirm the generation (2002-2006 or 2007-2013).
2. Body Style: For 2007-2013, specify Sedan or Coupe. Remember the 2013 Sedan is a different generation.
3. Position: Front Left (Driver Side) or Front Right (Passenger Side). They are not interchangeable.
4. Engine Size: Struts for the 4-cylinder (2.5L) and V6 (3.5L) models may have different spring rates to account for engine weight. Using the wrong one will affect ride height and handling.

Replacement and Installation

Complete Assembly vs. Bare Strut

You can buy a "quick strut" or complete strut assembly, which includes the strut, coil spring, and mount all in one unit. Alternatively, you can buy a bare strut and reuse your old spring and mount.

• Complete Assembly: Safer, faster, and easier to install. Highly recommended for DIY mechanics.

• Bare Strut: Cheaper part cost, but requires a special tool (spring compressor) to swap the spring. Using a spring compressor is extremely dangerous if done incorrectly and can cause serious injury. This job is best left to professionals.

Related Parts

When replacing struts, it's a good time to inspect and potentially replace these related components:

• Sway Bar End Links: These often wear out at the same time and can cause clunking noises.
• Control Arm Bushings: Check for cracks or tears in the rubber bushings.
• Ball Joints: Check for any play or looseness.

Torque Specifications

Using correct torque is critical for safety. While specs can vary slightly by year and model, these are common values for the 4th generation (2007-2012) Altima. Always verify for your specific vehicle.

Cost Breakdown

Prices can vary significantly based on brand, location, and whether you do the work yourself. These are general estimates for a single front strut.
