Why Understanding Trailhawk Parts Matters
2017 Jeep Cherokee Trailhawk Parts: A Comprehensive Guide for Off-Road Enthusiasts
Whether you're a seasoned off-roader or a new Trailhawk owner, knowing the ins and outs of its specialized components is invaluable. This knowledge empowers you to:
- Perform preventative maintenance: Identifying potential issues before they become major problems.
- Choose the right replacement parts: Ensuring compatibility and optimal performance.
- Plan strategic upgrades: Enhancing the Trailhawk's capabilities to suit your specific needs.
- Diagnose problems accurately: Saving time and money on repairs.
- Appreciate the engineering: Gaining a deeper understanding of what makes the Trailhawk special.
Let's dive into the key parts that define the 2017 Jeep Cherokee Trailhawk.
1. Trailhawk-Specific Suspension and Lift
The suspension system is arguably the heart of the Trailhawk's off-road prowess. Unlike standard Cherokee models, the Trailhawk boasts a unique suspension setup that provides increased ground clearance and enhanced articulation.
- Lifted Suspension: The Trailhawk sits approximately one inch higher than other Cherokee trims. This additional ground clearance allows it to clear larger obstacles and navigate deeper ruts. This lift is achieved through longer springs and re-tuned shocks.
- Off-Road Tuned Shocks: The shocks are specifically designed to handle the rigors of off-road driving, providing improved damping and control over rough terrain. They are more robust and better equipped to handle impacts and vibrations.
- Increased Articulation: The suspension geometry is optimized to allow for greater wheel travel, enabling the tires to maintain contact with the ground even on uneven surfaces. This is crucial for maximizing traction and stability.
Practical Advice: When replacing suspension components, always opt for parts specifically designed for the Trailhawk model. Using standard Cherokee parts will negate the benefits of the lifted suspension and could compromise off-road performance. Consider aftermarket lift kits for even greater ground clearance, but ensure they are compatible with the Trailhawk's existing suspension components and don't overextend the suspension travel, which could lead to premature wear and tear.
Potential Challenges: Replacing suspension components can be challenging, requiring specialized tools and knowledge. If you're not comfortable working on your vehicle's suspension, it's best to consult a qualified mechanic.
2. Selec-Terrain Traction Management System
The Selec-Terrain system is a cornerstone of the Trailhawk's off-road capability. This electronic system allows the driver to select from various terrain modes, optimizing the vehicle's drivetrain, throttle response, and stability control for specific conditions.
- Auto Mode: The default mode, suitable for everyday driving.
- Snow Mode: Optimizes traction in snowy or icy conditions.
- Sport Mode: Provides a more responsive throttle and tighter steering for enhanced on-road performance.
- Sand/Mud Mode: Maximizes traction in soft, loose terrain.
- Rock Mode: Engages 4-Low, locks the rear differential (if equipped), and optimizes the vehicle for crawling over rocks and other obstacles.
Benefits: The Selec-Terrain system simplifies off-road driving by automatically adjusting various vehicle parameters to suit the terrain. This allows even novice drivers to confidently tackle challenging conditions.
Important Considerations: Understanding how each mode works and when to use it is crucial for maximizing its effectiveness. Consult the owner's manual for detailed instructions and recommendations.
3. Active Drive Lock 4x4 System
The Trailhawk comes standard with Jeep's Active Drive Lock 4x4 system, which provides superior traction and control in off-road situations.
- 4-Low Mode: Provides a lower gear ratio for increased torque and crawling ability.
- Rear Locker: Electronically locks the rear differential, ensuring that both rear wheels spin at the same speed, maximizing traction on slippery or uneven surfaces.
- Brake Lock Differential (BLD): Applies the brakes to spinning wheels, transferring torque to the wheels with more traction.
How-To Guide: Engaging 4-Low and the Rear Locker
- Stop the vehicle and shift into Neutral.
- Select Rock mode using the Selec-Terrain dial. This automatically engages 4-Low.
- For even greater traction, press the "4WD Low Lock" button (if equipped) to lock the rear differential. The "4WD Low Lock" button is located next to the Selec-Terrain dial.
- Shift into Drive or Reverse and proceed slowly.
Tips: Use 4-Low and the rear locker only when necessary, as they can put additional strain on the drivetrain. Disengage them when returning to smoother terrain.
4. Skid Plates and Rock Rails
The Trailhawk is equipped with skid plates and rock rails to protect vulnerable underbody components from damage during off-road excursions.
- Skid Plates: These steel plates shield the engine, transmission, transfer case, and fuel tank from rocks and other debris.
- Rock Rails: These heavy-duty rails protect the rocker panels from damage when navigating rocks and obstacles.
Benefits: Skid plates and rock rails provide essential protection for critical components, preventing costly repairs and keeping you moving on the trail.
Practical Advice: Inspect the skid plates and rock rails regularly for damage, especially after off-road trips. Replace them if they are bent or cracked. Aftermarket skid plates and rock rails offer even greater protection and durability.
5. Aggressive Tires and Wheels
The Trailhawk comes standard with aggressive all-terrain tires that provide superior traction on various surfaces.
- Aggressive Tread Pattern: The tires feature a deep, open tread pattern that provides excellent grip in mud, sand, and snow.
- Reinforced Sidewalls: The sidewalls are reinforced to resist punctures and cuts, making them more durable for off-road use.
- 17-inch Wheels: The 17-inch wheels provide a good balance between off-road performance and on-road comfort.
Important Considerations: While the stock tires are capable, consider upgrading to more aggressive mud-terrain tires for even better off-road performance. Be aware that more aggressive tires can increase road noise and reduce fuel economy.
6. Unique Exterior Styling
The Trailhawk's exterior styling is not just for looks; it also serves a functional purpose.
- Red Tow Hooks: Two red tow hooks are located at the front and one at the rear, providing secure attachment points for recovery straps.
- Black Hood Decal: Reduces glare and improves visibility during off-road driving.
- Unique Fascias: The front and rear fascias are designed to improve approach and departure angles, allowing the Trailhawk to clear obstacles more easily.
7. Engine and Transmission Considerations
While not exclusively Trailhawk-specific, the engine and transmission play a crucial role in its performance. The 2017 Trailhawk offered a few engine options.
- 2.4L Tigershark I4: While available, it's not the ideal choice for serious off-roading.
- 3.2L Pentastar V6: This is the preferred engine for the Trailhawk, offering ample power and torque for tackling challenging terrain.
Both engines are paired with a nine-speed automatic transmission. While this transmission has had its share of criticisms, it provides a wide range of gear ratios that can be beneficial for both on-road and off-road driving.
Potential Challenges: The nine-speed transmission can sometimes exhibit rough shifting or delayed engagement. Regular maintenance, including fluid changes, can help mitigate these issues.
