Why Your 2017 Jeep Cherokee Needs New Front Struts
Your Jeep’s struts are more than just shock absorbers; they’re a critical component of the suspension system. They support the vehicle’s weight, absorb bumps, and maintain tire contact with the road. Over time, especially with the demanding life of an off-road enthusiast, these components wear out.
Recognizing the signs of failing struts early can save you from bigger problems down the line.
Common Symptoms of Worn Front Struts
- Excessive Bouncing and Body Roll: If your Jeep continues to bounce after hitting a bump, or sways significantly around corners, your struts are likely failing.
- Nose Dive During Braking: A pronounced forward dip when you apply the brakes is a classic sign of worn front suspension components.
- Clunking or Rattling Noises: Loose or worn strut mounts and bushings often produce metallic clunks or rattles, especially over rough terrain or speed bumps.
- Uneven Tire Wear: Failing struts can lead to improper wheel alignment and uneven tire wear patterns, reducing tire life.
- Fluid Leaks: Visual inspection might reveal oil or hydraulic fluid leaking from the strut body, indicating a seal failure.
- Reduced Steering Responsiveness: A “loose” feeling in the steering wheel or difficulty maintaining a straight line can also point to worn struts.
Don’t wait until these issues become severe. Addressing them promptly ensures a safer and more enjoyable driving experience, both on and off the pavement.
Gathering Your Gear: Tools and Replacement Parts
Before you begin any work, ensure you have all the necessary tools and the correct replacement parts. Being prepared prevents frustrating delays and ensures a smoother process.
Essential Tools for the Job
- Jack and Jack Stands: Absolutely critical for safely lifting and supporting your vehicle. Never work under a vehicle supported only by a jack.
- Wheel Chocks: To prevent the vehicle from rolling.
- Socket and Ratchet Set: Including various sizes (typically 18mm, 19mm, 21mm, 22mm for strut bolts, and lug nut size).
- Torque Wrench: Essential for tightening bolts to factory specifications, preventing over-tightening or loosening.
- Pry Bar or Large Screwdriver: Useful for separating components.
- Breaker Bar: For stubborn, rusted bolts.
- Penetrating Oil (e.g., WD-40, PB Blaster): Apply generously to all nuts and bolts you plan to remove well in advance.
- Wire Brush: To clean threads before reassembly.
- Gloves and Eye Protection: Safety first!
- Optional: Impact Wrench/Gun: Can significantly speed up bolt removal.
- Optional: Spring Compressor: ONLY if you are replacing the strut cartridge within your existing coil spring. We highly recommend using quick-strut assemblies to avoid this dangerous tool.
Choosing the Right Replacement Struts
For a 2017 Jeep Cherokee front strut replacement, you generally have two main options:
- Complete Strut Assemblies (Quick-Struts): These are the easiest and safest DIY option. They come pre-assembled with a new strut, coil spring, strut mount, and boot. No spring compressor is needed.
- Strut Cartridges/Shocks Only: This involves disassembling your existing strut, compressing the coil spring to remove the old cartridge, and installing a new one. This requires a spring compressor, which can be dangerous if not used correctly. For DIYers, quick-struts are almost always the preferred choice.
Consider your driving habits. Are you sticking to pavement, or are you looking for improved off-road performance? Brands like KYB, Monroe, Bilstein, and Gabriel offer reliable OEM-style replacements. For off-roaders, consider heavy-duty options or lift-compatible struts from brands like Old Man Emu or Rancho if you’re planning a suspension upgrade.
2017 Jeep Cherokee Front Strut Replacement: A Step-by-Step Guide
This guide assumes you are installing complete quick-strut assemblies. Always refer to your vehicle’s service manual for specific torque specifications and any unique steps for your trim level.
Step 1: Prepare Your Jeep for Service
- Park your Jeep on a flat, level surface.
- Engage the parking brake firmly.
- Chock the rear wheels to prevent any movement.
- Loosen the lug nuts on the front wheels you’ll be working on, but do not remove them yet.
- Using your jack, lift the front of the vehicle until the tires are off the ground.
- Place jack stands securely under the frame rails, near the front. Lower the vehicle onto the jack stands.
- Remove the lug nuts completely and take off the front wheels.
Step 2: Disconnect Necessary Components
Now that you have clear access, it’s time to start disconnecting. Remember to spray all bolts with penetrating oil if they look rusted.
- Disconnect the Brake Line Bracket: Locate the brake line and ABS sensor wire bracket attached to the strut assembly. Use a small wrench or socket to remove the bolt holding it in place. Be careful not to damage the lines.
- Disconnect the Sway Bar Link: The sway bar end link connects to the side of the strut. You’ll typically find a nut securing it. You may need an Allen key to hold the stud while loosening the nut to prevent it from spinning.
- Remove the Lower Strut Bolts: At the bottom of the strut, where it connects to the steering knuckle (or lower control arm), you’ll find two large bolts. These can be very tight. Use a breaker bar or impact gun if available. Once the nuts are off, you may need a pry bar to tap the bolts out.
Some Cherokees might have a single large pinch bolt securing the strut into the knuckle. Confirm your specific setup before proceeding.
Step 3: Accessing and Removing the Top Strut Mount
The top of the strut is secured under the hood.
- Open the hood and locate the three nuts holding the top of the strut mount to the strut tower.
- With the lower strut bolts removed, the entire strut assembly might sag. Support the steering knuckle or lower control arm with a separate jack or a block of wood to prevent it from hanging freely and straining other components like the axle or ball joints.
- Carefully remove the three top strut mount nuts. Once these are off, the entire strut assembly will be free.
- Slowly lower the steering knuckle/control arm and guide the old strut assembly out from the wheel well. This might require some wiggling and rotating.
Take note of how the old strut was oriented for easier installation of the new one.
Step 4: Installing the New Strut Assembly
Installation is essentially the reverse of removal. Be mindful of correct orientation.
- Position the New Strut: Carefully guide the new quick-strut assembly into the wheel well and up into the strut tower. Ensure the top mounting studs align with the holes in the strut tower.
- Secure the Top Mount: Hand-tighten the three nuts onto the top strut mount studs under the hood. Do not fully torque them yet.
- Connect the Lower Strut Bolts: Raise the steering knuckle/lower control arm with your jack until the lower strut mounting holes align with the strut. Insert the two large lower strut bolts and hand-tighten the nuts.
- Reattach Sway Bar Link: Reconnect the sway bar end link to the new strut. Tighten the nut.
- Reattach Brake Line Bracket: Secure the brake line and ABS sensor wire bracket back onto the strut.
Double-check all connections before moving on. Make sure nothing is pinched or misaligned.
Step 5: Final Torquing and Reassembly
This step is crucial for safety and longevity.
- Torque All Bolts: Using your torque wrench, tighten all nuts and bolts to the manufacturer’s specified torque values. This includes the three top strut mount nuts, the two lower strut bolts, and the sway bar link nut. Refer to your service manual for exact specs.
- Reinstall Wheels: Mount the wheel back onto the hub. Hand-tighten the lug nuts.
- Lower Vehicle: Lift the vehicle slightly with the jack to remove the jack stands. Slowly lower the Jeep to the ground.
- Final Lug Nut Torque: With the vehicle on the ground, torque the lug nuts to the manufacturer’s specification in a star pattern.
Repeat the entire process for the other side. Always replace struts in pairs to maintain balanced handling and prevent uneven wear.
Post-Replacement Checks and Alignment
Once both front struts are replaced, a few critical steps remain to ensure everything is perfect.
Initial Test Drive
Take your Jeep for a short, cautious test drive. Listen for any unusual noises, feel for any vibrations, and check the steering response. Pay attention to how the vehicle handles bumps and turns.
Wheel Alignment is Non-Negotiable
Whenever you replace front suspension components like struts, a wheel alignment is absolutely essential. Even if you think you put everything back perfectly, the slightest change in geometry can throw off your alignment. Ignoring this step will lead to:
- Rapid and uneven tire wear.
- Poor handling and steering.
- Increased fuel consumption.
Schedule a professional alignment immediately after your 2017 Jeep Cherokee front strut replacement. This ensures your tires last longer and your Jeep tracks straight and true.
Upgrading Your Struts for Off-Road Performance
For the true off-road enthusiast, replacing worn struts offers a perfect opportunity to upgrade. Standard OEM struts are designed for comfort and general road use. Off-road driving puts significantly more stress on suspension components.
Considerations for Off-Road Upgrades
- Increased Travel: Look for struts designed to offer more suspension travel, which is crucial for articulation over uneven terrain.
- Heavy-Duty Construction: Upgraded struts often feature larger diameter bodies, stronger shafts, and more robust seals to withstand harsh conditions and heavy loads (like recovery gear or roof racks).
- Lift Kits: If you’re installing a lift kit, ensure your new struts are compatible with the increased ride height. Many lift kits include specific struts designed for the new geometry.
- Adjustability: Some aftermarket struts offer adjustability for damping, allowing you to fine-tune your ride for different terrains or loads.
- Durability: For overland travel or frequent challenging trails, investing in high-quality, durable components from reputable off-road suspension manufacturers pays off in the long run.
Discuss your off-road goals with a specialist or experienced fellow off-roader to choose the best strut upgrade for your 2017 Jeep Cherokee.
When to Call a Pro
While a 2017 Jeep Cherokee front strut replacement is a manageable DIY task for many, there are situations where calling in professional help is the smartest move.
- Rusted or Seized Bolts: If you encounter severely rusted or seized bolts that won’t budge even with penetrating oil and a breaker bar, attempting to force them can lead to broken bolts and more complicated repairs.
- Lack of Proper Tools: If you don’t have a torque wrench, reliable jack stands, or the correct sockets, it’s safer to let a professional handle the job.
- Unfamiliarity with Suspension Work: If you’re uncomfortable working with heavy components or lack basic mechanical experience, there’s no shame in seeking expert assistance.
- Complications: If you encounter unexpected issues, such as damaged control arms, ball joints, or seized tie rod ends during the process, a professional can diagnose and repair them safely.
- Spring Compressor Use: If you opt to replace just the strut cartridge and need to use a spring compressor, and you’re not experienced with it, take it to a shop. Compressed springs store immense energy and can cause serious injury.
Your safety and the integrity of your vehicle are paramount. Don’t hesitate to consult a certified mechanic or a reputable off-road shop if you’re in doubt.
Frequently Asked Questions About 2017 Jeep Cherokee Front Strut Replacement
How long does a 2017 Jeep Cherokee front strut replacement take for a DIY mechanic?
For an experienced DIYer using quick-struts, it can take 2-4 hours per side. For a beginner, expect 4-6 hours per side, especially if encountering rusted bolts. Having the right tools makes a significant difference.
Do I need to replace both front struts at the same time?
Yes, absolutely. Always replace struts in pairs (both front or both rear). Replacing only one can lead to uneven handling, premature wear on the new strut, and an unbalanced ride.
What’s the difference between a strut and a shock absorber?
While often used interchangeably, a strut is a structural component of the suspension system, combining a shock absorber, coil spring, and upper mount into one unit. A shock absorber is just the damping component and is typically separate from the spring in other suspension designs.
How often should front struts be replaced on a Jeep Cherokee?
Typically, struts last between 50,000 to 100,000 miles. However, this can vary greatly depending on driving conditions, especially if your Jeep sees a lot of off-road use, carries heavy loads, or lives in an area with harsh roads. Regular inspections are key.
Will replacing my struts improve my Jeep’s off-road capability?
Yes, especially if your old struts were worn out. New struts restore proper suspension function, improving articulation, ground clearance (if worn struts were sagging), and overall control over uneven terrain. Upgrading to performance-oriented off-road struts can further enhance capability.
Replacing the front struts on your 2017 Jeep Cherokee might seem like a daunting task, but with the right tools, careful planning, and a commitment to safety, it’s a completely achievable DIY project. Not only will you save money, but you’ll gain a deeper understanding of your vehicle and the satisfaction of a job well done.
Enjoy the newfound comfort, improved handling, and restored confidence your Jeep will offer. Whether you’re commuting to work or venturing deep into the backcountry, a well-maintained suspension is your ticket to a great ride. Stay safe, stay comfortable, and keep exploring!
