CV Joints and Axles – What You Need To Know

What should you know about CV joints and axle shafts? Most cars and SUV’s these days are front wheel drive. The drive axle that puts engine power to the front wheels must allow for the tires to turn for steering, and for the suspension to go up and down. This requires the axle shaft to have what is called a constant velocity joint, or CV joint. CV joints have a rubber boot that allows the joint to move but also holds in grease so the joint stays lubricated. Over time this corrugated rubber boot can tear in the seams. Because the axle shaft is spinning the grease will be flung out of the boot through the tear, and road grime will be allowed to enter the joint. The eventual lack of grease and any debris will cause the joint to wear out. A worn out CV joint will normally make a clicking noise while driving when the front wheels are turned for a corner. We always check for CV boot damage when a car is in for service so we can let you know that you have a problem coming up. We normally don’t replace the boot itself, since axles don’t cost very much and it costs more labor to pull the axle apart to replace the boot. Replacing the whole axle is usually just slightly more than replacing the boot, and you get a new axle and new CV joints. So, if you hear a clicking sound while turning, it’s time to get it checked out. If you’re in for service and are told you have a torn CV boot, you can decide how soon you want to get that axle replaced.
