Just like any other part of your luxury car, a Porsche CV axle can become stubborn when the time comes. It can just either go bad, have a leak, form holes, or lose grease among others. When you notice that there is something wrong with your CV axles, you should decide to replace them. You can also do this on your own just by simply taking note of the following.
Remove the Axle Nut
You can see the axle nut after you have removed the vehicle's hubcap. Each wheel has a hubcap and make sure you remove only those whose CV axles need to be replaced. You must also remove the cotter pin which is found in the axle nut. This looks like a bobby pin whose ends can be folded back in order to hold the nut in place. Get pliers to help straighten out the ends of the cotter pin so that you can easily remove it. From here, you can proceed to removing the axle nut. It may take some torque so that you can remove this that is why you should do this step before you even jack up your vehicle.
Remove the Wheel and Brake Assembly
After you have jacked up the car, you can proceed to removing the wheel. You need to take a look at the vehicle manual to make it a point that you are jacking up the car the right way. Make sure that your car is in parking mode with the parking brake also engaged. From here, you can secure the car on jack stands.
When removing the wheel, you will see that the lug nuts are already exposed. This happens because you have already taken off the hubcap. Remove the nuts and do the procedure in the same manner you would when changing tires. Remove the brake caliper as well. Remove the outer tie rod which is connected to the steering knuckle. The steering knuckle can be seen behind the rotor. You will also need remove the bolts from the hub located in the strut tower.
Replace the CV Axles
The first thing to do in this part of the process is to work by prying the CV joint using either a flathead screwdriver or a pry bar. In case there is a problem with loosening the axle, you can twist it back before forcibly breaking the seal. Do not fret if transmission liquid leaks out in the process. This is normal but make sure you have something ready to catch the leaking fluid.
Now you are about ready to insert the new axle right into the car's transmission housing. All you have to do is insert the new axle right into that spot where the old axle has been removed from. The small clip will snap once the axle is in place. The new axle likewise should be reinserted into the hub assembly's center. Refasten all parts you have removed following the order in which you have removed them. You will need to replace old and worn out lug nuts, cotter pins, and anything else you know that needs replacement. Install the wheel and tighten the axle nut to finish up the process.
