Kia Sportage: Removing and Replacement of a CV Axle
This video and discussion show you how to remove and replace the right (passenger side) CV axle on a Kia Sportage. A nylon strap or rope can be used to "snap out" the axle from the transmission. This repair can also be performed on a Hyundai Tuscon (2005-2007).
Kia Sportage (Passenger Side) CV Axle Shaft Replacement (Video)
This five-minute video will provide you with visual step-by-step help for completing the removal and replacement of Kia Sportage passenger side CV axle. The steps are also described lower down in the article.
Step-by-Step Instructions: Kia Sportage CV Axle Shaft Replacement
1. Removing the CV Axle Nut
- Remove the CV axle nut cotter pin.
- Using a 32-mm socket attached to a powered impact driver, torque the CV axle nut off of the CV axle. If no powered impact tool is available, brace the wheel hub from moving by taking a long and strong metal bar (such as a crowbar) and bracing the bar on the ground and on two wheel hub lugs. Either a breaker bar or cheater bar will be needed to generate enough torque to remove the axle nut.
- Gently tap the CV axle shaft (preferably with a brass hammer as to not damage the threads) to get the shaft moving past the wheel hub splines. If the shaft will not budge, use a heavy punch tool to pound the shaft loose through the splines.
2. Removing the ABS Line Bracket, Lower Strut Bolts and Brake Caliper
- Disconnect the ABS line connected to the suspension strut.
- Remove the brake line clip that holds the brake line to the suspension strut. A pair of pliers can help pull the clip off.
- Remove the two nuts that hold the brake caliper assembly to the steering knuckle. Pull the caliper away from the brake rotor. Support the caliper so that the brake line is not stretched and potentially damaged.
- Remove the two nuts and bolts that secure the steering knuckle to the lower suspension strut. Wiggle the knuckle off, or place a pry bar between the strut and the knuckle until they are separated.
- Push or tap the CV axle shaft through the wheel hub until the two are separated.
3. Removing the CV Axle From the Transmission
- Remove the splash guard that covers the crank shaft and harmonic balancer. The guard is held in place with 10-mm bolts.
- Since there are no leverage points from which a pry bar or any other tool can pull and dislodge the axle from the transmission, I used a nylon strap with a hook on the end to remove the axle. I wrapped or looped the strap around the base of the inner CV housing and fastened with the strap hook. Allowing around two feet of slack, I applied a series of sharp pulls on the strap to jerk the axle out.
4. Installing the New CV Axle
- Position the axle into the transmission where the splines slide into the splines of the transmission. Pushing on the CV housing will eventually snap the housing shaft into the transmission.
- Insert the other end of the CV axle into the wheel hub and screw on the new axle shaft nut. Use a powered impact driver to torque down on the nut. If a powered impact driver is not available, the nut can be torqued down later. Otherwise, install the cotter pin.
5. Installing the ABS Line Bracket, Lower Strut Bolts and Brake Caliper
- Wiggle the steering knuckle onto the suspension strut. Align the mounting holes and push in the two mounting bolts. Screw on the bolt's nuts and torque down.
- Mount the brake caliper, with the brake pads attached, over the brake rotor and align the mounting holes. Screw on the two mounting bolts and torque down.
- Attach the brake line to the suspension strut and install the brake line clip. Light taps with a blunt object will push the clip into place.
- Attach the ABS line bracket to the suspension strut.
- Install the splash guard and bolt back into place.
Torqueing Down the CV Nut
If you don't have a powered impact tool, prevent the wheel hub from moving, as described in the removal procedure in section I above, and torque down the CV nut. Use approximately 150 lbs of torque. Using a torque wrench would be advisable.
