Axle boot

got my oil changed and they told me the right front axle boot is broken. Wondering what estimated repair costs would be and how serious this is. Is it something that could potentially fall apart while I'm driving? is something that left unrepaired can induce further suspension issues on the vehicle.

My car has 102530 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
You would need to have the axle replaced or the boot replaced if there is no joint damage. The joint will get damaged from dirt and debris getting in it when the boot is torn. The labor to replace the axle is a minimum of 1.5 hours in most cases. The axle is procured and priced locally to you. If you would like to have a second opinion on the vehicle, a certified professional from YourMechanic can come to your car’s location to inspect the suspension and guide you through repairs.

Of course, in that scenario, the new (or often rebuilt) axle will have all new rubber boots. So, to answer your basic question, yes, no matter how the repair to the axle, or individual CV joints, is carried out, your vehicle will have new boots on the CV joints, if work is done on an “axle”.
It is possible to drive a car with a torn CV boot, but doing so will likely lead to further damage that will eventually require more extensive repair.
If no noise is present and only the CV boot is broken, you can replace just the CV boot. Tip: Before you install a new axle, check the CV joints (even when the boot is broken) and see if they are worth saving. If you need to replace the CV axle completely, the new CV axle will come with the boots already installed.
The most common cause of CV joint failure is from the deterioration and splitting or tearing of the rubber CV Boot. Once split the protective CV joint grease escapes and dirt, road grime and water can enter the joint and cause the CV joint to wear rapidly and fail prematurely.
If the boot that seals the CV joint is damaged, the grease will leak out and contamination will set in, eventually causing the joint to wear out and fail. 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.
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.
There is no real set time how long the bad joint will last, and it may last a year or a month. A YourMechanic technician can travel to your location and help and replace the axle CV joint boot as soon as possible.
Bad or damaged engine mounts will cause the cv axle to keep breaking, overloading vehicles beyond its capacity and stress the axles with large bumps and potholes also will damage the cv joint too. Another way drivers can put their CV parts at greater risk is by adding lift kits to their vehicle.

You never want to add too much grease to a CV joint. The CV joint can get hot due to internal friction and heat transferred from the brakes and engine. The heat can cause the grease and air inside the joint to expand. The pressure can cause the boot to be forced off the body of the joint.
CV joints are packed with grease for lubrication. To keep the grease in the joint and moisture, dirt and roadway grime out, the joint is covered with a rubber boot called a CV boot. CV boots are made of a durable rubber that can withstand extreme weather and travel conditions.
The CV joints, or axles, are covered by a sealed plastic or rubber “boot”. The purpose of the boot is keeping dirt and moisture out. They also enclose the grease packed around the joint, which serves to lubricate the moving parts.
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.
Do CV Axles Need to Be Replaced in Pairs? No, you can replace just one axle if that is all you need. Some services like tire replacements can require you to install in pairs, but this is not the case for CV axles.
A CV axle can typically be expected to last for 80,000 to 100,000 miles under normal driving conditions. You`ll know when the axle is about to fail when you begin to hear a loud, rhythmic clicking noise coming from the front wheel as you turn. That noise is due to a lack of lubricant in one of the CV joints.
CV boots are vehicle specific with the exception of our EZ Trail Universal CV Boot so be sure to use our Parts Search to ensure proper OEM fitment. CV Boot Size Chart HERE.
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.
Inner CV joints connect the axle drive shafts to the transmission or differential, while the outer CV joints connect the axle drive shafts to the wheels. Depending on the type of suspension used, rear-wheel drive, all-wheel drive, and four-wheel drive vehicles may also have CV joints and boots.
Designed to be fitted without the need to dismantle any part of the suspension or driveshaft. The superior flexibility minimalises wear and tear especially when the vehicle is on full lock.
The play in the CV Axle joint causes the vibrations as the joint rotates thousands of times a minute. The rotation causes the joint to move inside the housing and bounce around accelerating the failure and causes the vibration you feel as your drive on the highway.
If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You`ll not be able to control the vehicle and may get involved in an accident.
How long do car axles last before replacement? CV axles, the most common type in today`s cars, last for 70K – 130K miles. So, they rarely break due to normal wear and tear; however, for safety`s sake, you must get your car axles inspected regularly.
If your CV joints ever fail completely, the car will suddenly not be able to accelerate, since it won`t have the means to transfer torque to the drive shaft or the wheels.

Transmission axle sea
ANSWER : You didn’t mention that you had the axle replaced but if you did the new axle may be the wrong one for your car, or you may have to get the replacement axle and seal from the dealer.

This vehicle in particular may have had a certain year of seal and axle, which then changed during the following year or mid year. The only way to get it correct may require the specific dealer parts by using your VIN number, it’s the only way to get the correct ones if you keep having issues with aftermarket parts. I’d recommend having a certified mechanic diagnose it to help you find the right replacement for your axle shaft seal.

Need to replace front left CV axle, do I need to replace the CV boot as well?
ANSWER : Hello, thank you for writing in. The damage done to the unit will dictate what exactly needs to be done. If the entire CV axle on one side or the other needs to be replaced, then the entire shaft is typically replaced at once, including the boots. If you need to replace part of the assembly, the boots are serviceable separately on a need be basis. In that case, you would need to know if you were replacing the inner (closest to the middle of the vehicle) or outer (closer to the tire) boot. Once you have made those determinations, corrective action can be taken. For more help with diagnostics or the repair, contact our service department to schedule an appointment.

Does the CV boot need to be replaced or do i need to replace the whole axle? 2008 Chevrolet Uplander
ANSWER : Hello – the CV joint or axle boot is available separately from a variety of sources. What your mechanic may be saying however, is that given your mileage, it would be best to replace the whole axle assembly for reliability reasons. Replacing the CV boot requires considerable labor as well, and your best repair $ may be to go ahead and replace the whole axle assembly. I would recommend a CV axle replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

How long can a car run with a broken CV axle boot?
ANSWER : The axle CV joint boot is there to hold the lubrication for the joint and keep out dirt and water. Without replacement, the joint grease comes out first and collects dirt within. The dirt acts as sand paper and grinds down the joint ball bearings. It will begin to click on turns for outside joints and click under load. There is no real set time how long the bad joint will last, and it may last a year or a month. A YourMechanic technician can travel to your location and help and replace the axle CV joint boot as soon as possible.

Replaced cv axle with non oem still getting clicking.
ANSWER : Hello. The play where the axle connects to the differential can be a bad bearing in the differential or more commonly the inner joint of the axle. Most of the time when this occurs it is because of a defective aftermarket axle. I would have used an OE new axle on this and if the play was still there then axle was replaced then the front differential will need to be rebuilt. If you want to have this axle issue looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose wht there is freeplay in the axle.

Driver side axle is leaking. Do I need to replace the axle and back struts before I get new tires and alignment?
ANSWER : Hello. Yes, I would recommend getting the axle seal, and the back struts replaced before having the alignment done and tires replaced. These two tasks will require having an alignment done after they have been replaced anyway, so it’s less expensive to only have to do the alignment once. And replacing the tires before having the alignment done risks tire wear if your suspension is worn and out of alignment now. If you need a professional to check this out, a certified professional from YourMechanic can come to your car’s location to diagnose the leak firsthand and advise on repairs.
