Checking CV joints is a crucial step in maintaining your vehicle’s drivetrain. CV joints, or constant velocity joints, are responsible for transmitting power from the transmission to the wheels, allowing them to turn smoothly even at extreme angles. When CV joints fail, it can lead to serious drivability issues and even safety hazards.
There are several telltale signs that may indicate a problem with your CV joints. These include clicking or popping noises when turning, vibrations in the steering wheel or floorboard, and difficulty accelerating or decelerating. If you experience any of these symptoms, it’s important to have your CV joints checked by a qualified mechanic as soon as possible.
Checking CV joints is a relatively simple process that can be performed with a few basic tools. First, raise the vehicle on a jack or lift and secure it with jack stands. Then, locate the CV joints, which are typically found at the ends of the driveshafts. Inspect the CV boots for any tears or cracks. If a boot is damaged, it can allow dirt and moisture to enter the joint, leading to premature failure.

When CV joints fail, it can lead to serious drivability issues and even safety hazards.
-
Binding or seizing
One of the most common causes of difficulty accelerating or decelerating is binding or seizing CV joints. CV joints are designed to move smoothly, but when they become damaged or worn, they can bind or seize, causing the wheels to lock up or become difficult to turn. -
Loss of lubrication
CV joints require lubrication to function properly. When CV joints lose lubrication, they can become damaged and worn, leading to difficulty accelerating or decelerating. -
Damaged CV boots
CV boots are rubber boots that protect the CV joints from dirt and moisture. When CV boots are damaged, they can allow dirt and moisture to enter the joint, leading to premature failure. -

FAQs on Checking CV Joints
Checking CV joints is a crucial aspect of vehicle maintenance, ensuring smooth operation and preventing costly repairs. Here are answers to some frequently asked questions about CV joint inspection:
Question 1: What are the telltale signs of faulty CV joints?
Faulty CV joints often manifest through clicking or popping noises during turns, vibrations in the steering wheel or floorboard, and difficulties accelerating or decelerating. These symptoms warrant prompt inspection by a qualified mechanic.
Question 2: How often should CV joints be checked?
Regular CV joint inspections are essential for early detection of issues. While specific intervals may vary based on driving conditions and vehicle usage, it is generally recommended to have them checked every 50,000 to 100,000 kilometers or as per the manufacturer’s guidelines.
Question 3: Can I check CV joints myself?
Checking CV joints involves inspecting the CV boots for tears or cracks, listening for unusual noises while turning, and attempting to move the joint by hand to detect any play.
