How To Remove CV Axle From Transmission In Simple Steps
A cv axle refers to the short form of constant velocity and connects two shafts that rotate while intersecting each other. The constant velocity axle joint is mostly used in front wheel drive cars.
The cv axle is responsible for evenly transmitting torque when the wheel moves while in steering or suspension. The constant vehicle axle also aids in the smooth transfer of engine power irrespective of the turning angle the steering wheel makes.
I rear wheel drive cars; the constant velocity joints are situated at the end of half shafts at the rear-axle. Various reasons may prompt you to remove the constant speed which includes to wearing out as well as damage.
What You Will Need
- A jack
- Pry bar
- Catch basin
- New constant velocity axle
Removing The CV Axle From Transmission
Step 1: Removal Of The Car's Hubcap
You can do this before jacking up your car. For wheels that have rims, the wheels may have a center cap instead of a hubcap. Removing the hubcap makes it easier to remove the constant velocity axle.
Step 2: Removal Of The Cotter Pin From The Axle Nut
The pin has folded ends which aid in holding it in place. In removing it, you will require using the pliers to straighten the folded ends. The pliers will make it easy for you to remove the cotter pin.
In case the pin is completely stuck in try using a penetrating lubricant from your closest automotive store. Apart from removing the cotter pin, the lubricant will also help with removing the axle nut as well.
Step 3: Removal Of The Axle Nut
This process is done after the cotter pin has been with drawn. The nut is likely to take some torque thereby making it wise and safer to remove it before jacking up your car. However, axle nuts aren’t made in standard sizes thus the difference in socket sizes of different vehicles.
The difference in socket sizes might require you to consult a skilled mechanic to determine the best and exact size needed for your car. Afterward, you can then carry on with the removal process.
Step 4: Brake Assembly And Wheel Removal
Depending on the Constant Velocity axle you need to replace, jack up the required side of the car. Ensure that your vehicle's parking brake is engaged before jacking up your car.
In jacking up, make sure you use the frame of your car and not the body since it might be fragile. Ensure that you use jack stands in the process to ensures that your car's body isn’t damaged.
Step 5: Remove The Wheel
After you are done jacking up, remove the wheel. Where by the hubcap is already removed, the lug nuts securing the wheel are exposed there by making it easy to remove the nuts.
Step 6: Remove The Brake Caliper
The brake caliber is only visible when you remove the wheel. Attached to the outside of the rotor, is the larger piece of housing the caliper. The caliper is held into place by bolts from the rear side.
Step 7: Unbolt The Outer Rod Tie From The Steering Knuckle
Just like the axle nut, unbolting the outer rod tie happens in the same manner. In case unbolting becomes tasking, you can consider spraying a lubricant. Afterward, tape the steering knuckle joint using a hammer.
This is done through hitting the knuckle where the rod passes through, to help remove it.
Step 8: Unbolt The Hub From The Strut Tower
You will find two 17mm bolts that connect the wheel hub to the strut power. When you remove these screws, the hub remains connected by the axle, through the center hole. This process makes removing it quite easy.
Step 9: Removal And Replacement Of The CV Axle
1) Separate The CV Joint
Look into the axle's back, and you will see the exact position and the joint where it slides into the transmission. In separation, use a pry bar which aids in separating the axle from the joint.
However, the axle may not easily get loose. In such a situation, try twisting it back and forth as you use force to break the seal. When doing this, some transmission fluid may leak out. Therefore, a catch basin is important.
The axle will be required to pass through a wishbone which is an enclosed piece. Remove the band from the inner boot for the old axle to go through.
2) Insertion Of The New CV Axle
In the same process, you removed the old axle; you will be needed to replace the space with the new constant velocity axle. In ascertaining the success of your replacement, the small C-clip on the axle will snap right into place.
In case you don’t feel the axle snap, use a rubber mallet by tapping it into place. Afterward, use the hub assembly to reinsert the new axle at the exact position the old one was.
3) Fasten All Removed Bolts
The bolts you untie in the replacement process need to be fastened back not unless they aren’t in good shape. If they are corroded, change them with new ones.
4) Reattach The Wheel
In reattaching the wheel do it in the same way you would when changing a tire. Lower your already jacked up car and take off the jack stands after you are done attaching the wheel.
5) Tighten The Axle Nuts
Do this when your vehicle is firmly on the ground. While doing so, ensure that you have your parking brake engaged.
When you follow the above steps in this article, you will have successfully changed/removed the constant velocity axle from the transmission. When inserting the new axle, ensure it of high quality and dependable.
