Set the parking brake, loosen lug nuts, raise the vehicle, and remove the wheel. Unstake the axle shaft/hub nut, remove the brake caliper and disc, disconnect the tie-rod end, and separate the control arm balljoint. Slide the axle shaft out of the hub, place a drain pan under the inner CV joint, and remove the heat shield. Pry out the inner CV joint, slide the intermediate shaft out, and clean the splines on both CV joints. Apply grease to the inner CV joint, seat the snap-ring, and ensure it's seated. Insert the splined shaft into the differential gears, install the bearing bolts, and tighten them. Install the heat shield, tighten the strut bolts, and stake the axle shaft/hub nut. Check and add transaxle lubricant if needed, and tighten the lug nuts.

Power is transmitted from the transaxle to the wheels through a pair of axle shafts, each consisting of an inner and outer constant velocity (CV) joint connected together by an axle shaft, with the inner ends of the axle shafts equipped with a tri-pot type joint and the outer ends with a ball-and-cage design, or "Rzeppa" joint. The boots should be inspected periodically for damage and leaking lubricant, and the most common symptom of worn or damaged CV joints is a clicking noise in turns, a clunk when accelerating after coasting and vibration at highway speeds. To check for wear in the CV joints and axle shafts, grasp each axle and rotate it in both directions while holding the CV joint housings, feeling for play indicating worn splines or sloppy CV joints, and also check the axle shafts for cracks, dents and distortion.
