Having a bad CV joint can cause your vehicle to pull, which can be an extremely dangerous situation when driving. The constant pulling can lead to over-steering and even under-steering, which could result in loss of control of the car or worse. The CV joint connects two components together: the wheel and the transmission. Its job is to transfer power from one component to another while allowing for some flexibility as you turn corners or drive on uneven surfaces. When it’s worn out or damaged, the force needed for turning will be much greater than normal, causing your car to pull either toward the left or right side of road depending on where the issue originates from. It can also create excessive vibrations that affect both steering and braking performance - making it harder for you to stay in control at all times. To prevent this dangerous problem from happening, it’s important that you get regular inspections done on your vehicle so any potential issues with your CV joints are identified early and fixed before they become a bigger problem down the road.
