2021 Nissan Altima Aftermarket Parts

The 2021 Nissan Altima is a reliable and popular sedan, but like any vehicle, it can experience wear and tear over time. Fortunately, a wide range of aftermarket parts are available to address common issues and enhance your Altima's performance. This article provides practical solutions to some frequent problems faced by Altima owners, along with guidance on selecting and installing appropriate aftermarket parts.

Problem: Weak or Failing Brakes

One of the most critical safety components of any vehicle is its braking system. Altima owners may encounter issues like squealing brakes, reduced stopping power, or a soft brake pedal. These symptoms often indicate worn brake pads, rotors, or even a failing master cylinder.

Solution: Replacing Brake Pads and Rotors

Replacing brake pads and rotors is a relatively straightforward task for DIY enthusiasts. However, if you're uncomfortable working on your brakes, it's always best to consult a qualified mechanic.

Required Tools:

  • Jack and jack stands
  • Lug wrench
  • Socket set
  • Wrench set
  • C-clamp or brake caliper tool
  • Brake cleaner
  • Torque wrench
  • Gloves and safety glasses

Aftermarket Parts to Consider:

  • Ceramic Brake Pads: These pads offer excellent stopping power, low dust, and quiet operation. Brands like Akebono, Power Stop, and Bosch are popular choices.
  • Drilled and Slotted Rotors: These rotors provide improved heat dissipation and wet weather performance compared to standard rotors. EBC Brakes and StopTech are reputable manufacturers.
  • Stainless Steel Brake Lines: Upgrading to stainless steel brake lines improves brake pedal feel and reduces brake fade by minimizing expansion under pressure.

Approximate Cost: Replacing brake pads and rotors on all four wheels can range from $300 to $800, depending on the brand and type of parts chosen. Labor costs, if applicable, can add another $200-$400.

Solution: Addressing a Failing Master Cylinder

A failing master cylinder can manifest as a soft brake pedal, difficulty stopping, or even complete brake failure. This is a serious issue that should be addressed immediately.

Aftermarket Parts to Consider:

  • OEM Replacement Master Cylinder: A direct replacement from Nissan or a reputable aftermarket manufacturer like ATE or Wagner is recommended.

Important Note: Replacing a master cylinder requires bleeding the brake system, which can be tricky. It's often best left to a professional mechanic to ensure proper operation and safety.

Approximate Cost: A replacement master cylinder can cost between $150 and $300. Labor costs for replacement and bleeding the brake system can range from $150 to $300.

Problem: Suspension Issues (Rough Ride, Poor Handling)

Over time, the Altima's suspension components can wear out, leading to a rough ride, poor handling, and excessive body roll. Common culprits include worn struts, shocks, and sway bar links.

Solution: Replacing Struts and Shocks

Replacing struts and shocks can significantly improve ride quality and handling. Aftermarket options offer a range of performance levels, from stock replacements to sport-tuned upgrades.

Required Tools:

  • Jack and jack stands
  • Socket set
  • Wrench set
  • Spring compressor (required for replacing struts)
  • Torque wrench
  • Penetrating oil
  • Alignment tools (alignment is highly recommended after strut/shock replacement)

Aftermarket Parts to Consider:

  • KYB Excel-G Struts/Shocks: These are high-quality, direct replacements that offer a comfortable ride and improved handling.
  • Bilstein B6 Performance Struts/Shocks: These are a more performance-oriented option, providing firmer damping and improved control.
  • Complete Strut Assemblies: These assemblies include the strut, spring, and mount, making installation easier. Monroe and Gabriel offer complete strut assemblies.

Approximate Cost: Replacing struts and shocks can range from $400 to $1200, depending on the brand and type of parts chosen. Labor costs, including alignment, can add another $300-$600.

Solution: Replacing Sway Bar Links

Worn sway bar links can cause clunking noises and reduced handling stability. Replacing them is a relatively simple and inexpensive repair.

Aftermarket Parts to Consider:

  • Moog Sway Bar Links: Moog offers durable and reliable sway bar links for the Altima.
  • Energy Suspension Sway Bar Bushings: Replacing the sway bar bushings along with the links can further improve handling and reduce noise.

Approximate Cost: Sway bar links typically cost between $20 and $50 each. Labor costs for replacement are generally around $50-$100 per link.

Problem: Dim or Yellowing Headlights

Over time, the Altima's headlight lenses can become cloudy or yellowed, reducing visibility and safety. This is a common issue caused by UV exposure and oxidation.

Solution: Replacing Headlight Assemblies or Bulbs

There are several options for addressing dim or yellowing headlights.

Aftermarket Parts to Consider:

  • Replacement Headlight Assemblies: Installing new headlight assemblies is the most effective way to restore clear and bright headlights. Depo and TYC are reputable aftermarket brands. Consider upgrading to projector headlights for improved beam pattern and light output.
  • LED Headlight Bulbs: Upgrading to LED headlight bulbs can significantly increase brightness and improve visibility. Ensure the bulbs are compatible with your Altima's headlight housings and are DOT-approved for street use. Brands like Philips, Osram, and Sylvania offer high-quality LED bulbs.
  • Headlight Restoration Kits: These kits can help remove oxidation and restore clarity to existing headlight lenses. They're a more affordable option than replacing the entire assembly, but the results may not be as long-lasting.

Approximate Cost: Replacement headlight assemblies can range from $150 to $400 per pair. LED headlight bulbs typically cost between $50 and $150 per pair. Headlight restoration kits are usually priced between $20 and $50.

Problem: Issues with the Continuously Variable Transmission (CVT)

The 2021 Altima, like many modern vehicles, uses a CVT. While generally reliable, CVTs can experience issues such as slipping, jerking, or unusual noises. Proper maintenance, including fluid changes, is crucial.

Solution: CVT Fluid Change and Potential Replacement

Regular CVT fluid changes are essential for maintaining the transmission's health. Consult your owner's manual for the recommended fluid change interval. If you're experiencing significant transmission problems, replacement may be necessary.

Aftermarket Parts to Consider:

  • Genuine Nissan CVT Fluid: Using the correct fluid is critical for CVT performance and longevity. It's highly recommended to use genuine Nissan CVT fluid or an approved equivalent.
  • Aftermarket CVT Filters: Consider replacing the CVT filter during fluid changes to ensure optimal fluid cleanliness.
  • Remanufactured CVT Transmission: If your CVT is severely damaged, a remanufactured transmission may be the most cost-effective solution. Jasper Engines & Transmissions is a reputable provider of remanufactured transmissions.

Important Note: CVT fluid changes require specific procedures and tools. It's often best left to a qualified mechanic to ensure proper fluid level and avoid damage to the transmission. Replacing a CVT is a major repair and should only be performed by experienced professionals.

Approximate Cost: A CVT fluid change can range from $150 to $300. A remanufactured CVT transmission can cost between $3000 and $5000, including installation.

By addressing these common issues with quality aftermarket parts, you can keep your 2021 Nissan Altima running smoothly and reliably for years to come. Remember to always consult your owner's manual and consider seeking professional assistance when dealing with complex repairs or safety-critical components. Always prioritize safety and quality when selecting aftermarket parts for your vehicle.
