It is not a complicated job but it does require some special tools. If you aren't familiar with working on stuff like this, which I am assuming you aren't, it is likely not something you'll be able to just whip out. Expect a mess, swearing, and bloody nuckles along with a variety of new tools.

You should also consider changing the wheel bearing since you will be in that area doing the cv axle.

I called a mechanic to get estimate to change the CV joint, they told me depending on the version of the axle shaft I have the price is diffrent.

they said one version is $851
and the other version they don't make it anymore, it is called Raised Lips, and that would be 1212, to fix it.


do you guys know about that two different types of the axle shaft?

I haven't heard about there being different versions on the front axles, but maybe. Either way, I at those prices that is close to what I would expect a dealer to charge for an entire new axle, not just a CV joint. I was in a pinch once and bought a reman axle from napa for $90. It lasted about two years and 40k miles before the boot failed. You can get GNK (which are high quality, may be OEM) for $260. A skilled mechanic should be able to swap it out in less than two hours. Prices near a grand are a joke.

do you have link to GNK ones?

btw I watched a youtube a guy wrapped the boot hole with a bike tire and secured it with Zip ties. since my car hasn't made any noise after 7 hours of driving. do you think I should fill the hole with grease and wrap it with a bike tube and zip it ?
I just want the car to last me for the winter. (4-5 months)

link to the youtbue guy, https://www.youtube.com/watch?v=PIanZCLILIM what do you think ?

You obviously don't want to fix this. You keep saying it isn't making noise anymore and now you want to wrap a inner tube around it. For Gods sake, just f'n sell it or go buy a honda. This is a basic repair, and the fact you let it go so long is proof you have no intention of repairing it correctly. I get sick of people using duct tape on a $60K dollar car. And it is an older car, it needs maintenance. Just sell it

No. The CV joint is wearing at an accelerated rate because of the contaminates, the noise going away isn't a good thing and does not mean that it is no longer wearing. Worst case it seizes up while driving.

Just have a local shit shop replace the outer CV joint with that $50 one for a couple hundred bucks.

Here is a link to the parts

As I mentioned earlier the GKN can be sourced through Turner motorsports. Its not that expensive.
