Understanding CV Axles

Originally found mainly in front-wheel drive vehicles, CV (Constant Velocity) axles are now a key component in both front-wheel and rear-wheel drive systems. The CV axle assembly—which includes the axle shaft, CV joints, and CV boots—flexibly transfers power to your wheels, ensuring a smooth and consistent torque delivery. Positioned between the drive wheels, the CV axle works in conjunction with the suspension system to compensate for road irregularities while maintaining steady wheel rotation. The inner CV joints link the axle to the transmission, while the outer CV joints connect the axle to the wheels. A well-maintained CV axle assembly enhances vehicle stability, safety, and passenger comfort across various speeds and driving conditions.

Signs You May Need a CV Axle Replacement

Over time, the CV axle assembly naturally wears out due to its constant movement and exposure to extreme conditions. Warning signs that your CV axle may need replacement include:

• Hesitation or resistance while turning
• Loud clicking or popping noises when making turns
• Shaking or vibrations while driving

However, some symptoms can also indicate other issues, such as misaligned wheels or uneven tread wear. Regular maintenance of your CV axle assembly helps extend its lifespan and can prevent costly repairs. Driving with a failing CV axle can cause additional damage to your vehicle, leading to more extensive repairs. If you notice any of these signs, contact Sunland Tire for a professional CV axle replacement service.
