2004 Nissan Xterra Aftermarket Parts

The 2004 Nissan Xterra: a rugged, reliable SUV known for its off-road capabilities and practical design. However, even the toughest vehicles require maintenance and upgrades over time. If you're facing common issues with your 2004 Xterra or simply looking to enhance its performance, aftermarket parts offer a cost-effective and customizable solution. Let's delve into some frequent problems and how aftermarket parts can help you get back on the road (or off it!).

Common 2004 Xterra Issues and Aftermarket Solutions

1. Suspension Problems: Sagging, Rough Ride, and Reduced Off-Road Performance

One of the most common complaints with older Xterras is a sagging or worn-out suspension. This manifests as a noticeable lean, a bumpy ride, and diminished off-road prowess. The culprit? Worn-out shocks, struts, leaf springs, and bushings.

The Solution: Aftermarket suspension components offer a variety of options, from direct replacements to complete lift kits. Consider these:

Shocks and Struts: Aftermarket brands like Bilstein, KYB, and Rancho offer improved damping and durability compared to stock. Expect to pay around $50-$150 per shock/strut. Replacing these yourself is possible with basic tools like a socket set, wrenches, and spring compressors (which can often be rented). A professional shop will typically charge $150-$300 per axle for labor.
Leaf Springs: If your Xterra is sagging significantly in the rear, consider replacing the leaf springs. Deaver Spring and Old Man Emu are reputable brands. New leaf springs can cost $200-$500 per pair. Replacing them involves loosening the U-bolts and spring eye bolts, which can be seized. Penetrating oil is your friend! A professional installation will likely cost $200-$400.
Lift Kits: If you're looking to improve off-road clearance and articulation, a lift kit is the way to go. These kits range from simple spacer lifts (less expensive, but can limit suspension travel) to complete suspension systems with new control arms and shocks. Prices range from $200 for a basic spacer lift to $2000+ for a comprehensive long-travel kit. Installation is more complex and typically requires professional assistance, adding another $500-$1500 to the cost.
Bushings: Worn bushings contribute to sloppy handling and clunking noises. Polyurethane bushings are a popular aftermarket upgrade, offering increased stiffness and durability compared to rubber bushings. Energy Suspension and Prothane are well-known brands. Replacing bushings requires pressing tools, so it's often best left to a shop. Expect to pay $50-$200 for a bushing kit and $100-$300 in labor per axle.

Pro Tip: When upgrading your suspension, consider the overall goal. Are you looking for a smoother ride on the road, improved off-road capability, or a combination of both? Research different options and read reviews to find the best fit for your needs. Don't forget to get a wheel alignment after any suspension work!

2. Engine Performance Issues: Loss of Power, Poor Fuel Economy, and Rough Idle

As your 2004 Xterra ages, engine performance can decline due to worn-out components. Common issues include a loss of power, poor fuel economy, and a rough idle.

The Solution: Several aftermarket parts can help restore and even improve engine performance:

Cold Air Intake: A cold air intake can improve airflow to the engine, potentially increasing horsepower and fuel economy. K&N and AEM are popular brands. Expect to pay $150-$300. Installation is relatively straightforward, requiring only basic tools.
Performance Exhaust System: An aftermarket exhaust system can reduce backpressure, leading to improved engine performance and a more aggressive sound. Magnaflow and Flowmaster are common choices. Cat-back systems typically cost $300-$600. Installation can be done at home with the right tools (saw, wrenches, and potentially an exhaust hanger removal tool) but can be challenging if the old exhaust is rusted. A shop will likely charge $100-$300 for installation.
Spark Plugs and Wires: Replacing worn spark plugs and wires can significantly improve engine performance and fuel economy. Use high-quality aftermarket spark plugs like NGK or Denso. Expect to pay $20-$50 for spark plugs and $30-$80 for spark plug wires. Replacing these is a relatively simple DIY task.
Throttle Body Spacer: While the benefits are debated, a throttle body spacer can potentially improve throttle response and low-end torque. They typically cost $50-$100 and are easy to install.
Performance Chip/Tuner: A performance chip or tuner can remap the engine's computer, optimizing performance for specific modifications or driving styles. Bully Dog and Superchips are popular brands. These can range from $300-$700. Installation usually involves plugging the tuner into the OBDII port.

Pro Tip: Before investing in performance upgrades, ensure that your engine is properly maintained. Replace filters (air, fuel, oil), check for vacuum leaks, and ensure the timing is correct. Address any underlying mechanical issues before adding performance parts.

3. Drivetrain Issues: Slipping Transmission, Clunking Diffs, and Worn CV Joints

The drivetrain is crucial for transferring power from the engine to the wheels. Common issues include a slipping transmission, clunking differentials, and worn CV joints.

The Solution: Aftermarket parts can address these issues and improve drivetrain performance:

Transmission Cooler: A transmission cooler can help prevent overheating, extending the life of your transmission, especially if you tow or off-road frequently. B&M and Hayden offer reliable coolers. Expect to pay $50-$150 for the cooler and $100-$300 for installation.
Differential Cover: An aftermarket differential cover can provide increased oil capacity, improved cooling, and added protection for the differential gears. ARB and Mag-Hytec are popular brands. They typically cost $150-$400. Installation involves draining the differential oil, removing the old cover, and installing the new one.
CV Axles: Worn CV axles can cause clicking or popping noises, especially when turning. Aftermarket CV axles from brands like Cardone or Napa offer a cost-effective replacement option. Expect to pay $80-$200 per axle. Replacing CV axles requires removing the wheel, brake caliper, and hub assembly. It can be a challenging DIY job, and a professional will likely charge $150-$300 per axle.
Locking Differentials: For serious off-roaders, a locking differential can provide increased traction by locking both wheels on an axle together. ARB Air Lockers and Eaton E-Lockers are popular choices. These are a significant investment, costing $800-$1500 per differential, plus installation (which can be $500-$1000 per axle).

Pro Tip: Regularly inspect your drivetrain components for signs of wear and tear. Check for leaks, unusual noises, and excessive play. Changing the differential and transmission fluid at recommended intervals is crucial for preventing problems.

4. Body and Exterior Upgrades: Protection and Aesthetics

Beyond mechanical repairs, aftermarket parts can also enhance the appearance and functionality of your 2004 Xterra.

The Solution: Consider these upgrades:

Bumpers: Aftermarket bumpers offer increased protection and improved approach and departure angles for off-roading. ARB, Smittybilt, and HeftyFabworks offer a wide range of options. Expect to pay $500-$2000+ for a front or rear bumper. Installation can be complex, especially with winches, and a professional shop will likely charge $200-$500 for installation.
Rock Sliders: Rock sliders protect the rocker panels from damage when off-roading. Shrockworks and White Knuckle Off Road offer durable sliders. Expect to pay $300-$800 per set. Installation typically involves welding or bolting the sliders to the frame.
Roof Racks: A roof rack provides additional cargo carrying capacity. Thule and Yakima offer versatile roof rack systems. Expect to pay $200-$500 for a basic roof rack and $100-$300 for accessories like cargo carriers or bike racks. Installation is usually straightforward.
Lighting: Upgrading to LED headlights, fog lights, or auxiliary lights can significantly improve visibility. Rigid Industries and Baja Designs are popular brands. Prices vary widely depending on the type of light and brand. Installation can be as simple as replacing a bulb or require more complex wiring.

Pro Tip: When choosing body and exterior upgrades, consider the intended use of your Xterra. If you plan on serious off-roading, prioritize protection. If you're primarily using it for commuting, focus on aesthetics and functionality.
