What Does a Shaking Wheel Feel Like?
The shaking in my Ford Focus was hard to miss. It started as a slight vibration in the steering wheel when I pressed the gas, but it grew stronger as I sped up. The whole car felt unsteady, like it was struggling to stay balanced.
The sensation was most noticeable between 40 and 60 mph, and it sometimes felt like the wheels were out of sync. If you’re feeling a wobble, shimmy, or vibration that gets worse when you accelerate, you’re likely dealing with one of a few common issues. Let’s dive into what I considered as I tracked down the problem.
Common Causes of Wheel Shaking During Acceleration
I’ve worked on enough cars to know that a shaking wheel can stem from several culprits. When I felt that wobble in my Focus, I ran through the possibilities based on past experiences. Here’s what I considered:
Unbalanced Tires
Tires that aren’t properly balanced can cause a noticeable shake, especially when accelerating. I’d had this issue before on an old SUV after hitting a pothole, which threw the wheel weights off. The vibration tends to get worse at higher speeds, just like what I was feeling.
Worn or Damaged Tires
Uneven tire wear or a damaged tire can also cause shaking. I once had a tire with a bubble in the sidewall that made the car wobble like crazy. If the tread is worn unevenly or there’s physical damage, the wheel won’t roll smoothly.
Wheel Alignment Issues
Misaligned wheels can make the car pull to one side and cause vibrations. I’d experienced this after swapping out suspension parts on a friend’s car. The shaking from misalignment often worsens during acceleration or when turning.
Worn CV Joints or Axles
The constant-velocity (CV) joints in front-wheel-drive cars like my Focus can wear out over time. A damaged CV joint can cause a shaking sensation, especially when accelerating through turns. I’d replaced a CV axle on a previous car, so this was high on my list.
Warped Brake Rotors
If the shaking happens during acceleration and braking, warped rotors might be the issue. I’d dealt with this on an older truck, where the rotors were so warped they caused a pulsing sensation in the steering wheel.
Loose or Damaged Wheel Bearings
Wheel bearings allow the wheels to spin smoothly. When they wear out, they can cause a wobble or vibration. I’d replaced bearings before, and the symptoms were similar to what I was feeling, so I kept this in mind.
My Diagnosis Process: Tracking Down the Shake
I’m a hands-on guy, so I decided to diagnose the issue myself before heading to a shop. I grabbed my tools, a jack, and some patience, and got to work. Here’s the step-by-step process I followed to figure out why my car wheel was shaking when I accelerated.
Step 1: Test Driving to Pinpoint the Issue
I took the car for a slow drive around my neighborhood, paying close attention to when the shaking happened. The vibration was strongest when I accelerated past 40 mph and seemed to come from the front end. It was less noticeable when coasting or braking, which ruled out warped rotors for me. The shaking also got worse in turns, which made me suspect the CV joints or tires.
Step 2: Visual Tire Inspection
I jacked up the car and secured it with jack stands to inspect the tires. I checked each one for uneven wear, bulges, or damage. The front tires looked okay, but I noticed the tread was wearing unevenly on the driver’s side.
This could mean alignment issues, but I wasn’t convinced that was the whole story. I also spun each wheel by hand to feel for resistance—everything felt smooth, so wheel bearings seemed unlikely.
Step 3: Checking Wheel Balance
To test for balance issues, I took the car to a local tire shop where I know the guys. They put each wheel on a balancing machine, and sure enough, the front driver’s-side wheel was out of balance.
The tech showed me how the wheel wobbled on the machine, and we added some weights to fix it. I drove the car afterward, but the shaking was still there, though slightly better. So, I kept digging.
Step 4: Inspecting the CV Joints
Since the shaking was worse during acceleration and turns, I suspected the CV joints. I got under the car and checked the CV boots for tears or leaks. The driver’s-side boot was torn, and grease was leaking out—a clear sign the joint was failing. I’d seen this before on another car, and it matched the symptoms perfectly.
Step 5: Ruling Out Other Causes
To be thorough, I checked the wheel bearings by grabbing each wheel and trying to wiggle it. There was no play, so the bearings were fine. I also inspected the brake rotors for warping, but they looked even and smooth. The alignment was a possibility, but I decided to focus on the CV joint first since the symptoms lined up.
Fixing the Wheel Shake: Replacing the CV Axle
Once I confirmed the CV joint was the issue, I decided to replace the entire CV axle. I’d done this job before, and while it’s not the easiest, it’s doable with some effort. Here’s how I tackled it.
Gathering Tools and Parts
I ordered a new CV axle for my Focus from an auto parts store—it cost about $80 for a quality aftermarket part. I also grabbed a new axle nut, some penetrating oil, and a tube of high-temperature grease for good measure. My toolbox already had everything else: a socket set, breaker bar, torque wrench, pry bar, and jack stands.
Removing the Old Axle
I jacked up the car, removed the wheel, and loosened the axle nut with a breaker bar. Getting the axle out was the hardest part—it was stuck in the hub, so I used penetrating oil and a few gentle taps with a rubber mallet.
I also had to disconnect the lower ball joint to free the axle from the transmission. It took some muscle, but after about 30 minutes, the old axle was out.
Installing the New Axle
The new axle slid into place easily once I greased the splines. I reconnected the ball joint, torqued the axle nut to spec (about 200 ft-lbs for my Focus), and reinstalled the wheel. The whole job took about two hours, including a few breaks to curse at stubborn bolts.
Test Driving the Fix
After lowering the car, I took it for a test drive. The shaking was gone—no more wobble, no more vibration. The car felt smooth and steady, even at highway speeds. I was relieved, and honestly, a little proud of myself for tackling it at home.
Comparing CV Axle Options
To help you choose the right CV axle, here’s a comparison based on my experience with different types:
| Type | Pros | Cons | Best For |
|---|---|---|---|
| OEM Axle | Perfect fit, reliable, long-lasting | Expensive, harder to find | Those who want factory quality |
| Aftermarket Axle | Affordable, widely available | Quality varies, may wear out faster | Budget-conscious DIYers |
| Remanufactured | Cost-effective, eco-friendly | Risk of defects, shorter warranty | Drivers looking to save money |
I went with an aftermarket axle because it was half the price of an OEM part and had a decent warranty. So far, it’s held up great.
Other Fixes for Wheel Shaking
If your wheel shake isn’t caused by a CV joint, here’s how I’d approach other potential issues based on past experiences:
Tire Balancing
If the tires are unbalanced, a quick trip to a tire shop can fix it for $20-$40. I’ve had tires balanced multiple times, and it’s a cheap, fast solution for vibrations.
Tire Replacement
For worn or damaged tires, replacement is the only fix. I’ve bought mid-range tires for about $100 each, and they’ve lasted years. Check for bulges or uneven wear before buying new ones.
Wheel Alignment
A professional alignment costs about $80 and can fix shaking caused by misaligned wheels. I get my alignment checked every year or after hitting a bad pothole.
Brake Rotor Replacement
Warped rotors need resurfacing or replacement. I’ve replaced rotors for about $50 each, plus $20 for new brake pads. It’s a straightforward job if you’re comfortable with brakes.
Wheel Bearing Replacement
Bad bearings are a bigger job. I replaced one on an old SUV, and it cost $200 at a shop because I didn’t have a press. If you hear a rumbling noise, this might be it.
Preventing Wheel Shaking in the Future
After fixing the CV axle, I made a plan to keep this issue from coming back. Here’s what I do to prevent wheel shaking:
- Inspect Tires Regularly: I check tire tread and pressure every month. Proper inflation prevents uneven wear.
- Get Regular Alignments: I schedule an alignment every 12 months or after any suspension work.
- Check CV Boots: I look under the car every oil change to spot tears or leaks in the CV boots.
- Drive Carefully: Avoiding potholes and rough roads helps protect tires, axles, and bearings.
- Listen for Warning Signs: A slight vibration or noise can be an early clue. I catch issues early to avoid bigger repairs.
Emotional Reflections on Car Repairs
Fixing a shaking wheel can feel daunting, especially when you’re not sure what’s causing it. I remember feeling frustrated when the tire balancing didn’t fully solve the problem—it’s easy to second-guess yourself. But once I found the bad CV joint, it was like a weight lifted off my shoulders.
There’s something rewarding about solving a car problem yourself. It’s not just about saving money; it’s about knowing your car inside and out. If you’re feeling stressed about a shaking wheel, take it one step at a time. You’ll get there.

Frequently Asked Questions
Why does my car wheel shake only when I accelerate?
In my experience, a shaking wheel during acceleration often points to a worn CV joint, like the one I found on my Focus. The vibration happens because the joint isn’t transferring power smoothly to the wheel, especially under load. Unbalanced tires or alignment issues can also cause this.
Can I drive with a shaking wheel?
I wouldn’t recommend it for long. When my car’s wheel was shaking, I drove it sparingly until I fixed the CV axle. Driving with a bad joint or tire can damage other components and make the problem worse.
How much does it cost to fix a shaking wheel?
It depends on the cause. Balancing tires costs $20-$40, while a new CV axle, like the one I replaced, is about $80 for parts if you do it yourself. A shop might charge $200-$400 for axle replacement or $80 for an alignment.
How do I know if my CV joint is bad?
A bad CV joint usually causes shaking during acceleration, especially in turns. I confirmed mine by checking the CV boot for tears and grease leaks. If the boot is damaged, the joint is likely failing.
How can I prevent my car wheel from shaking?
Regular maintenance is key. I check my tires, alignment, and CV boots routinely to catch issues early. Driving carefully and avoiding rough roads also helps keep your wheels steady.
