How Much Does an Axle Boot Replacement Cost?
Here’s a breakdown of the total cost:
A. Range
The average cost of an axle boot or CV boot replacement is between $300 and $510.
This includes:
- Parts cost: $50 to $150
- Labor cost: $250 to $360
B. Factors Affecting Cost
The following factors can influence your total CV boot replacement cost:
- Vehicle model and transmission type: The complexity of the repair job can vary depending on your car’s model and whether it’s front-wheel, rear-wheel, or all-wheel drive. This can influence the overall labor cost.
- Location: Mechanics in urban or high-cost areas typically charge more than those in smaller towns or rural areas.
- Original Equipment Manufacturer (OEM) or aftermarket alternatives: An OEM axle boot typically ensures the best fit and performance, but can be costly. An aftermarket axle boot is cheaper but less durable.
- Related repairs: Replacing a Constant Velocity (CV) boot may uncover a bad CV joint or a broken axle. A CV joint replacement will cost a whopping $1,000 to $1,080 extra.
Is It Worth Replacing an Axle Boot?
Yes, definitely.
The axle boot covers the CV joint and holds in the grease that lubricates the joint and keeps out dirt from the road.
If the CV joint boot is damaged, the grease will leak out, and dirt will get in. This can cause the CV joint to wear out fast, leading to a more costly repair, like an entire axle replacement.
Worn axle joints can also affect your steering and stability, making your vehicle unsafe to drive, especially at higher speeds or during turns.
4 Warning Signs You Need an Axle Boot Replacement
Some red flags of a torn CV boot include:
- Clicking when turning: If you hear a clicking noise when turning the steering wheel, it could mean the CV joint is loose, often due to a damaged boot.
- Grease on your wheel or tire: Look for green grease marks, especially in a circular pattern on the inside of your wheel or tire. This means grease is leaking from a torn boot while the axle spins.
- Vibrations while driving: A damaged boot can let dirt and moisture into the CV joint, which wears it out and causes vibrations.
- A bumpy ride: If your ride feels bumpier or less stable than normal, it might be due to CV joint damage caused by a torn boot.
How Is a Damaged CV Boot Replaced?
You can check for an axle boot leak by looking underneath the vehicle. However, you should leave the task of replacing a damaged axle boot to an auto repair professional. The process requires the right tools and precise torque settings to ensure everything is reassembled correctly.
But if you still wish to know, here’s how a mechanic will perform a CV boot replacement:
- Raise the vehicle off the ground using a jack, and place a wheel chock behind the wheels.
- Take off the wheel on the side where the axle boot needs replacement.
- Remove the CV axle from the vehicle and place it on a workbench.
- Use a pair of diagonal cutting pliers to cut and remove the torn CV boot.
- Wipe off any old grease and debris from the axle shaft.
- Slide the new axle boot onto the shaft. Ensure the wide end of the boot faces the CV joint.
- Apply fresh grease to the CV joint.
- Install the CV joint back onto the axle shaft, securing it in place.
- Slide the boot over the CV joint and ensure it sits evenly. Then, tighten the boot clamps on both ends to hold it firmly.
- Place the CV axle back into the vehicle. Reattach any components removed for access, following the manufacturer’s specifications.
- Put the wheel back on and carefully lower the vehicle back to the ground.
How Long Does an Axle Boot Last?
An axle boot can last an average of around 80,000 miles.
However, this can vary depending on driving conditions and climate. The boot is made of rubber, which is constantly exposed to heat, road debris, and weather changes. Over time, the rubber dries out and becomes brittle, making it more likely to crack or tear.
How to Extend the Life of Your Axle Boots
Here are a few tips to keep your CV boots in top condition:
- Check your axle boots every time you do an oil change, and even more often if you drive off-road or in rough conditions.
- Spray a light coat of silicone lubricant on the boots to help prevent them from drying out, cracking, or becoming brittle.
- Avoid driving through deep water or muddy terrain, whenever possible, as this can speed up wear on the boots.
- Clean the undercarriage thoroughly if you’ve driven through mud or water to remove debris that can damage the boots.
- Choose high-quality replacement boots that can handle heat, motion, and road stress better than cheaper alternatives.
