The national cost for a cv joint replacement in 2023 is between $385 and $861 with an average of $623.
The price to replace a CV joint, or joints, will depend on the age, make, and model of your vehicle. If you own a mainstream affordable vehicle, the price to replace a CV joint is likely to run in the range of $900 to $1200. The majority of the cost will be labor.
Replacing a CV Boot
Many repair shops, though, will recommend replacing the entire axle if a boot is torn because there may be unseen damage to the CV joints, axle shafts and other parts that could result in other problems. Outer boots (the ones closest to a wheel) are more prone to tears than inner boots.
Good quality ball joints cost $100 – $150. You`ll find cheaper ones for as low as $20 – $80, but it`s risky depending on your car`s make and model. Ball joint replacement costs for high-end cars can be $500 or more, as the part costs more. Labor costs are typically around $100 – $150.
CV axle boots last for quite some time (80,000 miles) and are not items needing periodic replacement. But you absolutely should inspect them at least once a year, or even more often on cars with high mileage. They are most affected by prolonged off-road driving or heavy use in transportation-industry conditions.
Labor Cost
Labor rates vary from shop to shop but normally it will take 1.5-3 hours to replace a cv axle. The total labor cost will depend on how many axles you are getting replaced. If you have an all-wheel-drive car and are replacing all four axles, the labor time can be 12 hours or more.
This knuckle is covered by the CV boot. The CV boot is used constantly when the car is in use. Usually, the CV boots will last about 80,000 miles before they have to be replaced.
A severely worn out CV joint can even disintegrate while you`re driving and make the car undrivable. You may lose control of the vehicle entirely. It is not safe to drive with a damaged CV joint. Look for some symptoms of a failing CV joint to have it repaired before it becomes unsafe to operate the vehicle.
As the damage worsens, a faulty CV can produce a loud click, popping, or clunk sound. When making a tight turn at a low rate, frequent brake noise at low speed (caused by damage to the outer CV joints) causes grinding noises. A bad CV joint also causes a vibration in the steering wheel and the car`s floorboard.
CV axles have bearings that allow for a wide range of motion and angles to provide both power and turning abilities. CV axles differ from straight axles seen in rear-wheel-drive cars whose job is to simply transfer power to non-steering wheels.
Replacing a CV joint yourself will save you a fair bit of money, but will require a decent amount of mechanical expertise and time. If you think the job is too complicated, it`s recommended that you leave the task to a qualified technician. This can also help protect you from voiding any motor plan or warranty.
CV joints and boots can be replaced individually, but most professional technicians and even do-it-yourselfers prefer to replace the whole halfshaft assembly with a remanufactured shaft.
Whenever a CV boot is replaced, the old grease will need to be removed and new grease added. You`ll also need to grease a CV joint during rebuilding processes, such as replacing an axle stub with a broken wheel speed sensor tone ring or replacing a CV joint.
CV axle failures are usually caused by a broken or leaking boot, which is often followed by failing bearings in a joint.
The most common problem with CV joints is when the protective boot cracks, tears, or becomes damaged. Once this happens, the grease leaks out and moisture and dirt get in, causing the CV joint to wear faster and eventually fail due to loss of lubrication, contamination, and corrosion.
You may be able to drive on a bad CV axle for several months, but it depends on the extent of the damage. We`re obliged to let you know that the safest thing to do is get the axle replaced immediately. The longer you wait, the worse the damage will be.
But the average lifespan of a bad CV axle is around five to six months.
It`s not always a worn boot that causes CV joints to fail. When the bolts attaching the inner joint to the transaxle or the outer joint to the wheels fail, the condition of the CV boot is irrelevant. Most gearheads know what happens to a CV (constant velocity) joint when the boot is torn or cracked.
If a CV joint begins to fail while driving, your car will start to pull to one side as one wheel loses power. When the joint breaks completely its corresponding wheel will no longer turn and although the engine may still run, the car won`t move.
The outer joint, which connects the driveshaft to the wheel, uses a ball joint. The inner joints, which connect the driveshaft to the transmission, usually use tripod joints. In order to ensure a smooth and full range of motion, a CV joint must remain adequately lubricated with grease.
A worn outer CV joint typically makes a clicking or knocking noise while turning, and perhaps under acceleration. Worn inner joints are less common, and may make similar noises during acceleration. Adding grease should not be necessary if the boots are in good condition.
The drivers side axle will have a male end on the CV joint with a retainer clip that goes into the transaxle. The passenger side has a female end on the inner CV joint. Both axles outer CV joints have male ends.
Greases containing moly are recommended for roller bearings subjected to very heavy loads and shock loading, especially in slow or oscillating motion such as found in universal joints and CV joints.
Penrite A Better Class of Oil CV Joint Grease is a premium heavy duty, lithium complex, NLGI No. 1. 5 grease containing molybdenum disulphide and graphite for boundary protection against the heaviest sliding, shock or impact loading conditions.
