CV Joint Replacement Services at Sunland Tire

Understanding CV Joints and Their Function

Your vehicle’s CV (Constant Velocity) joints are crucial components of the drive axle, connecting the transmission to the wheels to ensure smooth and efficient power transfer. Each drive axle has two CV joints:

• Inner CV joint – connects the transmission to the axle.
• Outer CV joint – connects the axle to the wheels.

CV joints allow for a wide range of motion while keeping the shafts securely connected, enabling the wheels to maintain a constant velocity across uneven terrain, bumps, and turns. Designed as a ball-and-socket mechanism, the CV joint consists of steel balls that allow smooth movement while being enclosed in a CV boot, which protects the joint and retains essential lubrication. A properly functioning CV joint is critical for maintaining stability, handling, and performance on all types of road surfaces.

Signs You May Need a CV Joint Replacement

Over time, CV joints wear down due to continuous movement, road stress, and loss of lubrication. Common warning signs of a failing CV joint include:

• Clicking or popping noises when turning
• Excessive vibrations while driving
• Loss of acceleration or difficulty turning

A torn or deteriorating CV boot can also lead to premature CV joint failure by allowing grease to leak out and dirt or debris to enter, causing internal wear. If a failing CV joint is not replaced promptly, it can cause severe damage to your axle and drivetrain, leading to costly repairs. Addressing CV joint issues early is far more affordable than dealing with major component failures down the road.
