If you are talking about just the boot, and not the whole CV Joint (Axle), then no it's not that expensive. The boot itself should be under $50 depending on your make and model of vehicle, and the labor, even at a dealership should not be all that bad. You can call your local dealership and get a price over the phone. Now if you need the whole thing, CV Joint, that can be expensive depending a lot on the vehicle. I had a Z-71 Silverado and the dealership wanted almost $1000.00 to replace the CV joint on it. After doing a little research I found out that most of the money for the repair was for the part itself. So I bought an aftermarket CV joint from Carquest for under $100.00 and had the dealership install it using my part from Carquest. The total bill was under $200.00. Hope this helps.
No.
It would be in your best interest to replace the entire CV shaft. Replacing the boot is only a temporary fix, because the bearings inside the torn old boot have been exposed to the elements (dirt/water), and will destroy the bearings.
Lift the vehicle using a jack. Inspect the CV boot for problems. Mark the axle. Separate the CV from the shaft. Remove the CV boot clamps. Use a mallet to knock the CV joint off the shaft. Remove the boot from the CV axle shaft.
The CV joint is the part inside the boot.
Inspect the boot and look for a tear or hole. If you see any the boot is bad and needs replacing. The joint itself will pop, and make noises if it is defective.Inspect the boot and look for a tear or hole. If you see any the boot is bad and needs replacing.

If the boot is torn, then more than likely the CV joint needs replacing. It at the very least needs to be inspected. You can replace the boot with a repair kit, but I would have the joint inspected.
I have just fitted both CV boots on a 1994 Peugeot 106. Though I only needed the outer one replacing I had to remove the inner CV joint to slip the boot over the outer CV bell end. As a result I had to replace inner boot and metal sleeve also. Job wasn't too difficult considering I am not a mechanic , only hard bit was removing the circlip on the inner CV joint, if you need further details, email me at ziamirza99@clara.co.uk and I can send you detail & pics of assembly.
A CV boot is found on the axle of a vehicle. To replace the outer boot remove the axle bolt and pull the boot off. The inner boot requires removal of the whole axle.
A cracked boot itself won't cause a CV joint to make noise. However, a cracked boot WILL cause the grease to be slung out and allow dirt to enter the CV joint. And a contaminated CV joint that is starved for lubricant WILL eventually start to make noise.
They make replacements that are split in half, but they aren't generally recommended. What's best (unfortunately) is to remove the shaft and replace it with a stock cv boot. If the cv boot has been open to the elements for a while, damage in the cv joint might have occured.
Keeps dirt out of it
Check the "boot" for cracks and see if there is any loss of grease. The boot is the rubber housing around the CV Joint. If the boot is damaged, grease has escaped and the CV Joint is making noise, the CV joint must be replaced.
