First Things First: When Does the Clicking Happen?
Before you grab a single tool, your most powerful diagnostic weapon is your ears. Paying close attention to when the clicking occurs is the first step in narrowing down the possibilities. Different conditions put stress on different parts.
Think like a detective. The clues are right there if you listen carefully. This is one of the most important can am defender clicking noise tips we can offer.
Clicking When Turning
If the clicking is most obvious or only happens when you’re turning the wheel left or right, your prime suspect is a worn-out outer CV (Constant Velocity) joint. These joints allow the axle to transfer power to the wheels while they turn and move up and down with the suspension.
When an outer CV joint wears, the internal ball bearings and cage develop play. This slack creates a distinct clicking or popping sound under the strain of a turn.
Clicking While Accelerating or Decelerating
A clicking noise that appears when you get on or off the gas points toward slop somewhere in the driveline. This could be anything from a failing U-joint on your driveshaft to play in the differential’s internal gears.
The sudden change in torque from accelerating or decelerating takes up this slack, causing a click or clunk. Inner CV joints can also cause this, though it’s less common than outer joint failure.
Clicking at a Constant Speed
A consistent click that matches wheel speed, regardless of turning or acceleration, can be a bit trickier. It could be a bad wheel bearing, but that’s often more of a grinding or humming noise.
More likely culprits include a rock stuck in a brake caliper, a loose lug nut, or something rubbing against the tire or axle with every rotation. Don’t overlook the simple stuff!
Clicking Only in 4WD
If the noise only appears when you engage four-wheel drive, you can immediately focus your attention on the front driveline components. This is a huge clue.
The problem is likely in the front differential, the front driveshaft, or the front CV axles. A common failure point on Can-Ams is the Sprague carrier (or roller cage) inside the front differential, which can make a clicking or ratcheting sound when it fails.
The Most Common Culprit: Checking Your CV Axles and Joints
In our experience, a bad CV axle is the cause of a can am defender clicking noise about 80% of the time. The rubber boots that protect the joints are vulnerable to rips and tears from sticks and rocks on the trail. Once that happens, grease escapes, and dirt and water get in, quickly destroying the joint.
How to Inspect Your CV Boots for Damage
This is your first and easiest check. You don’t even need to lift the vehicle. Turn your steering wheel all the way to one side to get a clear view of the front axles.
Carefully inspect the four rubber boots (two on each front axle, an inner and an outer). Look for any rips, tears, or pinholes. A tell-tale sign of a torn boot is grease splattered all over your suspension components and the inside of your wheel.
The “Wiggle Test” for Axle Play
For this test, safety is paramount. Make sure your Defender is in park on a level surface. Grab the axle shaft firmly with both hands and try to move it up-and-down and in-and-out.
A tiny bit of rotational play is normal, but there should be almost no vertical or horizontal movement. If you can feel a significant “clunk” or see a lot of movement at the joint, it’s a strong indicator that the CV joint is worn out.
Listening for the Tell-Tale Signs of a Bad CV Joint
If the visual and physical checks are inconclusive, find a safe, open area like an empty parking lot. Put the Defender in gear and drive slowly in a tight circle, both left and right.
A worn outer CV joint will typically make a loud, rhythmic clicking or popping sound during these tight turns. If it clicks turning right, the problem is likely the right-side CV, and vice versa.
Digging Deeper: Wheel Bearings and Hubs
While often associated with a grinding or humming noise, a severely failed wheel bearing can also cause a clicking sound. The bearing consists of small steel rollers that allow your wheel to spin freely. When they wear out, they can develop flat spots or break apart.
The Jack Stand Test: How to Check for a Bad Wheel Bearing
This is a critical part of any guide on how to can am defender clicking noise diagnosis. Safety first: Securely lift the corner of the Defender you suspect has the bad bearing and place it on a sturdy jack stand. Never work under a vehicle supported only by a jack.
Grab the tire at the 12 o’clock and 6 o’clock positions. Try to wiggle it by pushing with one hand and pulling with the other. Any play or clunking here points to a bad wheel bearing.
Next, grab the tire at the 9 o’clock and 3 o’clock positions and do the same. Play in this direction can also indicate a bearing issue, but it could also be a worn tie rod end, so inspect those as well.
With the wheel still in the air, spin it by hand. Listen closely and feel for any roughness or grinding. A good bearing will spin smoothly and silently.
Don’t Overlook the Simple Stuff: Brakes and Wheels
Before you start ordering expensive parts, always check the easy things first. We’ve seen many riders chase a phantom click for hours, only to find a simple, five-minute fix. These are some of the best practices to follow.
Inspecting Brake Calipers and Pads for Debris
Off-roading means mud, rocks, and sticks. It’s very common for a small pebble or piece of debris to get lodged between the brake pad and the rotor, or between the rotor and the dust shield.
Take the wheel off and use a flashlight to get a good look inside the caliper. A blast of compressed air or a quick spray with a hose can often dislodge the offending object and solve your clicking issue instantly.
Checking for a Warped Rotor or Sticking Caliper
A warped brake rotor can cause a click at a specific point in its rotation as it hits the brake pad. You can often feel this as a pulsation in the brake pedal when stopping.
A sticking caliper slide pin can also cause the caliper to not release properly, leading to odd noises. Ensure the caliper can move freely on its mounting pins.
Are Your Lug Nuts Torqued Correctly?
This sounds too simple, but it happens. If your lug nuts are loose, the wheel can shift slightly on the hub as it rotates, creating a clicking or creaking sound. Always use a torque wrench and tighten your lug nuts to the factory specification in a star pattern.
Driveline Diagnosis for Your Can Am Defender Clicking Noise
If you’ve checked the axles, bearings, and brakes without finding the culprit, it’s time to move toward the center of the machine. Driveline issues are less common, but they definitely happen, especially on hard-ridden machines.
Inspecting U-Joints on the Driveshafts
The universal joints (U-joints) on your front and rear driveshafts allow the shafts to change angle as the suspension moves. When they wear out, they can create a click, especially when transitioning from on-throttle to off-throttle.
With the machine in park, get underneath and firmly grasp the driveshaft near the U-joint. Try to twist it back and forth and push it up and down. Any perceptible play in the joint itself means it’s time for a replacement.
Checking for Issues with the Front or Rear Differential
Differential problems can range from low fluid to broken internal gears. The first step is to check the fluid level and condition. If the fluid is milky (water contamination) or has metal shavings in it, you have an internal problem.
A clicking from a differential often points to a chipped tooth on the ring or pinion gear, which requires a full rebuild. This is one of the more serious common problems with can am defender clicking noise.
A Sustainable Approach to Repairs and Maintenance
Fixing your Defender isn’t just about silencing a noise; it’s about ensuring reliability for years to come. Adopting a sustainable mindset means choosing quality over quick fixes and being mindful of your environmental impact.
Choosing Quality Parts for a Long-Term Fix
When you identify a failed part, like a CV axle, it can be tempting to buy the cheapest replacement you can find. This is often a mistake. A quality OEM or heavy-duty aftermarket part will last longer, perform better, and prevent you from having to do the same job again in six months. This is the core of a sustainable can am defender clicking noise solution.
Proper Disposal of Old Fluids and Parts
As you work on your machine, you’ll be dealing with gear oil, grease, and old metal parts. Be an eco-friendly DIYer. Never dump old fluids on the ground or in the trash. Your local auto parts store or recycling center will almost always accept used oil and other fluids for free. Scrap metal can also be recycled.
Preventative Maintenance: Your Best Care Guide
The best way to fix a clicking noise is to prevent it from happening in the first place. Regularly inspect your CV boots, check your fluid levels, and grease any zerk fittings on your suspension and driveline. A good can am defender clicking noise care guide is simply your machine’s service manual—follow it!
Frequently Asked Questions About Can Am Defender Clicking Noises
Is it safe to drive my Defender with a clicking noise?
It depends on the cause. If it’s a simple rock in the brake, it’s not a major safety issue. However, if it’s a failing CV joint or wheel bearing, it could fail completely, potentially causing you to lose control of the vehicle. It’s best to diagnose and fix the noise as soon as possible.
How much does it cost to fix a clicking CV axle?
If you’re doing the work yourself, a replacement CV axle for a Defender typically costs between $100 and $250, depending on the brand. If you take it to a shop, you can expect to pay an additional $150 to $300 in labor costs.
Can I replace a CV boot myself?
Yes, you can replace just the boot, which is much cheaper than a full axle. However, it’s a messy and labor-intensive job. If the joint has been clicking for a while, it likely has internal damage already, and replacing the full axle is the more reliable long-term repair.
What tools will I need for these checks?
For most of these diagnostics, you’ll need a good set of basic tools: a floor jack, jack stands, a set of metric sockets and wrenches, a torque wrench, pliers, and a pry bar. A good flashlight is also essential.
Diagnosing that pesky can am defender clicking noise can feel like a daunting task, but with a systematic approach, you can find the source and fix it. Start with the most likely culprits—the CV axles—and work your way through the list. Always prioritize safety, use the right tools, and don’t be afraid to ask for help.
By following this guide, you’ve gained the knowledge to tackle this common problem with confidence. Now get out in the garage, track down that click, and get your Defender back to running smoothly and silently on the trails. Happy wrenching!
