Can-Am Defender Lift Kit Problems

So, you're thinking about lifting your Can-Am Defender? Awesome! A lift kit can transform your machine, giving it a more aggressive stance, improved ground clearance, and the ability to tackle tougher terrain. But before you rush out and buy the biggest, baddest lift you can find, let's talk about the potential downsides. Installing a lift kit isn't always a walk in the park, and it can introduce some problems if you're not careful. We're here to help you navigate the potential pitfalls and ensure your Defender stays reliable and fun to ride.

The Lure of the Lift: Why We Want More Ground Clearance

Let's be honest, the main reason most of us want a lift kit is to conquer obstacles. Rocks, logs, deep ruts – a few extra inches of clearance can make all the difference between a smooth ride and a frustrating stuck situation. Larger tires often go hand-in-hand with lift kits, further enhancing your Defender's off-road prowess. The increased tire size and aggressive tread patterns provide better traction and grip, allowing you to tackle challenging terrain with confidence. Plus, let's face it, a lifted Defender just looks cool. That beefier, more imposing appearance is a definite draw for many riders.

The Not-So-Glamorous Side: Potential Problems Arise

While the benefits of a lift kit are undeniable, it's crucial to understand the potential drawbacks. Ignoring these issues can lead to premature wear and tear, reduced reliability, and even unsafe riding conditions. We're not trying to scare you off lifting your Defender, but we do want you to be informed and prepared.

Here's a breakdown of some common problems you might encounter:

• Axle Angles and CV Joint Stress: This is arguably the biggest concern with lift kits. Lifting your Defender changes the geometry of the suspension, increasing the angles of your axles. This puts more stress on the CV joints (Constant Velocity joints), which are responsible for transferring power from the transmission to the wheels. The steeper the angle, the greater the stress, leading to premature wear and potential failure. Think of it like bending a drinking straw too far – it eventually kinks and breaks.

  • Solutions: Opt for a lower lift (2-3 inches is generally considered safer). Consider high-clearance A-arms, which can help correct the axle angles. Invest in upgraded, heavy-duty axles designed to handle the increased stress. Regularly inspect your CV boots for tears and replace them promptly to prevent dirt and debris from damaging the joints.

• Steering Issues: Lift kits can also affect your Defender's steering geometry, leading to bump steer and reduced steering precision. Bump steer occurs when the wheels steer themselves slightly as the suspension moves up and down, making the vehicle feel unstable and unpredictable.

  • Solutions: Look for lift kits that include steering stop extensions or other components designed to maintain proper steering geometry. Consider aftermarket tie rods, which are stronger and more adjustable than the stock ones. Ensure proper alignment after installing the lift kit.

• Wear and Tear on Bushings and Ball Joints: The increased stress on the suspension components can accelerate wear and tear on bushings and ball joints. These parts are responsible for allowing the suspension to move smoothly and quietly. When they wear out, you might notice excessive play in the suspension, clunking noises, and reduced handling performance.

  • Solutions: Choose a lift kit with high-quality bushings and ball joints. Regularly grease the suspension components to keep them lubricated. Inspect the bushings and ball joints periodically and replace them as needed. Consider upgrading to aftermarket bushings made from more durable materials.

• Tire Rubbing: Installing larger tires, which often accompanies a lift kit, can lead to tire rubbing against the fenders or other parts of the vehicle. This can damage the tires, fenders, and suspension components.

  • Solutions: Carefully choose tire sizes that are compatible with your lift kit and Defender model. Consider using wheel spacers to push the wheels further out and create more clearance. Trim the fenders if necessary to prevent rubbing.

• Reduced Stability: Lifting your Defender raises its center of gravity, making it more prone to tipping over, especially on uneven terrain. This is particularly important to consider if you frequently ride on steep hills or off-camber trails.

  • Solutions: Avoid excessively high lifts. Install wheel spacers or wider wheels to increase the track width and improve stability. Be extra cautious when driving on uneven terrain. Avoid making sudden turns or maneuvers at high speeds.

• Driveshaft Issues: Depending on the lift kit and the angle of the driveshaft, you may experience increased vibration or even premature wear on the driveshaft and its U-joints.

  • Solutions: Ensure the lift kit is compatible with your Defender model and drivetrain configuration. Consider a driveshaft spacer or carrier bearing drop bracket if necessary to correct the driveshaft angle. Regularly inspect the driveshaft and U-joints for wear and tear.

• Installation Headaches: Installing a lift kit can be more challenging than you might expect, especially if you're not experienced with automotive or UTV mechanics. Improper installation can lead to a host of problems, including loose bolts, misaligned components, and damaged parts.

  • Solutions: Carefully read and follow the installation instructions. If you're not comfortable performing the installation yourself, hire a qualified mechanic. Double-check all bolts and fasteners to ensure they are properly torqued.

• Voiding Your Warranty: Installing a lift kit may void certain parts of your Defender's warranty, especially if the lift kit is determined to have caused a failure.

  • Solutions: Check with your Can-Am dealer or warranty provider before installing a lift kit to understand the potential impact on your warranty. Choose a lift kit from a reputable brand that is known for quality and reliability. Keep detailed records of the installation, including receipts and photos.

Choosing the Right Lift Kit: It's Not Just About Height

When selecting a lift kit for your Can-Am Defender, it's tempting to go for the tallest lift you can find. However, as we've discussed, higher isn't always better. The best lift kit for you will depend on your riding style, the type of terrain you typically encounter, and your budget.

Here are some factors to consider:

• Lift Height: As a general rule, a 2-3 inch lift is a good compromise between increased ground clearance and minimal stress on the suspension components. If you primarily ride on relatively flat terrain, you might not need a lift at all.

• Kit Quality: Choose a lift kit from a reputable brand that is known for quality and durability. Avoid cheap, generic lift kits, as they may be poorly made and prone to failure. Look for kits that include high-quality hardware, bushings, and ball joints.

• Ease of Installation: Consider your mechanical skills and the complexity of the installation process. If you're not comfortable performing the installation yourself, choose a kit that is relatively easy to install or hire a qualified mechanic.

• Components Included: Check to see what components are included in the lift kit. Some kits only include the lift brackets or spacers, while others include additional components such as steering stop extensions, high-clearance A-arms, or upgraded axles.

• Price: Lift kits can range in price from a few hundred dollars to several thousand dollars. Set a budget and stick to it. Remember that you may also need to factor in the cost of larger tires, wheel spacers, and installation.

Maintaining Your Lifted Defender: Prevention is Key

Once you've installed your lift kit, it's important to properly maintain your Defender to prevent problems and ensure its longevity.

Here are some tips:

• Regularly Inspect the Suspension: Check the bushings, ball joints, CV boots, and axles for wear and tear. Replace any worn or damaged parts promptly.

• Grease the Suspension Components: Keep the suspension components lubricated by greasing them regularly. This will help to prevent wear and tear and keep the suspension moving smoothly.

• Check the Alignment: Have your Defender's alignment checked periodically to ensure that the wheels are properly aligned. Misalignment can lead to uneven tire wear and reduced handling performance.

• Adjust Your Driving Style: Be more cautious when driving on uneven terrain, especially on steep hills or off-camber trails. Avoid making sudden turns or maneuvers at high speeds.

• Keep an Eye on Tire Pressure: Maintain the proper tire pressure to ensure optimal handling and tire wear.
