How Do I Replace The CV Joint Boot In My Car? The CV boots shield the CV joints from debris by completely enclosing them. Grease for lubrication purposes is kept inside the joints.

A “clicking” or “knocking” noise when turning is a common symptom of CV joint damage. To fix this, you’ll need a new CV axle. If the CV boot is damaged but the engine is otherwise silent, you only need to replace the boot.

Top Indicators Of A Damaged Cv Boot

  • A knocking noise can be heard while driving if the CV boot is worn out or has been damaged. The noise is most prominent near the car’s inner pivot point.
  • The tyre’s edge develops a small crack or tear and begins to leak grease. If you notice grease on your tyre, it may be a sign that the CV boot has worn out.
  • When driving, you may hear a clicking or popping sound whenever you turn the steering wheel. Damage to the CV boot necessitates its replacement.
  • Drivetrain Vibrations And Jolts Are Caused By A Faulty Cv Boot.
  • Vibrations coming from the CV axle: If dirt or water gets into the CV joint, you may feel vibrations while driving.

Changing Out A Cv Boot: Step-By-Step Instructions

Step 1

Drive the car onto a flat surface. If you’re handling everything on your own, turn the lug nuts clockwise by two full turns before lifting the car. The next step is to identify which side of the vehicle the CV boot needs to be replaced on. 

Once you realise this, you can use the jack to raise the vehicle and safely set it on a level surface. Make sure it doesn’t sag when you lift it up. Wheel chocks should then be positioned behind the back wheels for extra security. 

Remember that if the vehicle is lifted in an incorrect body frame location, undercarriage damage is possible.So exercise some caution in that regard. Put the safety stands under the vehicle so they can be supported properly.

Step 2

Once this is accomplished, you can take off the wheel by using a lug nut wrench. Meanwhile, check that there is someone in the vehicle who can use the brakes when necessary. 

If you do this, loosening the lug nuts will be even less of a hassle. To release the metal clamps, use the clamp clutters.Each side of the rubber shoe features a clamp. 

Once you’ve released the clamps, you can use a knife or blade to sever the old rubber boot from the shoe. In order to avoid injury, you should always begin cutting from the edge.

Step 3

In order to clean the axle and the joints, the next step is to obtain a bucket of water. Put the bucket under the spot you want to clean to protect the floor from any spills. 

Wear protective equipment, including goggles and gloves, at all times while carrying out these procedures. Get rid of the grime and old grease around the axle and joints with the aid of the parts cleaner. 

At this point, you can use the paper towels to clean up the mess. When you’re finished cleaning, throw the paper towel in the trash.

Step 4

We must now put in the new CV boot kit. To find the grease packages you need, look in the CV boot kit’s accessories. Now slit the grease bag open and begin applying it to the CV joints and axle. 

The CV shoe comes with pre-cut grooves already installed. To replace the boot over the axle, you need only remove the old one. 

Next, use the glue that came with the boot kit to secure the two halves of the boot together. When the glue dries, it will have the same pliability as rubber.

Step 5

Spread grease inside the CV boot to protect the pivot points. You’ll need to pay closer attention as you slide the CV boot into place. Make sure the larger end of the boot is positioned over the outer CV joints. 

The smaller of the two ends is used on the axle shaft. After the CV boot has been set in place, the metal clamps can be put in place with the help of clamp pliers. 

The safety stands should be taken down and the tyres put back on after this. Return the vehicle to a flat surface. Before you get behind the wheel, make sure the emergency brake is released.


How Do I Replace The CV Joint Boot In My Car?



Fixing a faulty CV boot can be a costly process. If, however, you do need to replace the boots, we’ve laid out everything you’ll need to know to do it on your own. 

A worn axle bearing could be the cause of torn axle boots. At that point, the entire axle will need to be replaced. A mechanic should be consulted if this is the case.


Can You Just Replace The Boot On A Cv Joint?

If the CV boot is damaged but the engine is otherwise silent, you need only replace the boot. 

A broken boot doesn’t mean the CV joints can’t be used, so test them out before you buy a new axle. The boots will be pre-installed on a new CV axle if you need to replace the entire axle.

Can A Cv Boot Be Repaired?

While split boot kits provide temporary relief, nothing beats a fresh pair of boots. The most cost-effective solution is a new or remanufactured replacement CV axle half shaft, but these aren’t readily available for low-production turbo specialty sports cars that are 30 years old, like the 1987 Mitsubishi Starion. You need to remove the axle first.

Is It Worth Replacing Cv Boots?

CV boots should be inspected at every service interval and replaced at the first sign of damage or wear to prevent the need for more expensive repairs to the CV joint or axles.

What Happens If You Don’t Replace Cv Boot?

A boot protects the opening to the Constant Velocity. When this boot is damaged, the joint will wear out and eventually fail. 

There’s no point in trying to drive a car with a damaged CV because doing so will only hasten the joint’s degeneration and make driving unsafe. You risk losing control of the vehicle and being in an accident as a result.

How Do Cv Boots Get Damaged?

Deterioration and subsequent splitting or tearing of the rubber CV Boot is the leading cause of CV joint failure. 

When a CV joint is damaged, the protective grease leaks out, allowing dirt, road grime, and water to enter the joint and accelerate wear and lead to an early failure.
