To remove the axle shaft, start by disconnecting the cable from the negative terminal of the battery. Set the parking brake and remove the wheel cover or hub cap. Remove the cotter pin and the bearing nut lock from the axle shaft/hub nut. Break loose the axle shaft/hub nut but leave it in place. Loosen the lug nuts on the front wheel, raise the vehicle, and support it securely on jack stands. Remove the wheel and any engine splash shields that may be in the way. Remove the axle shaft/hub nut. Then, remove the nuts and bolt securing the ball joint to the control arm and pry the control arm down to separate the components. To loosen the axle shaft from the hub splines, tap the end of the axle shaft with a soft-faced hammer or a hammer and a brass punch. If necessary, remove the brake disc and push the axle shaft from the hub with a two-jaw puller. Place a drain pan underneath the transaxle as a precaution. Remove the case protector if present. Pull out the steering knuckle to detach the axle shaft from the hub. If removing the right axle shaft, remove the center-bearing lock bolt and the snap ring, then pull the splined inner end of the shaft out of the differential side gear. For the left axle shaft, carefully pry the inner CV joint out of the transaxle. If the vehicle needs to be moved without the axle shaft, secure the hub with a large bolt and washers. For installation, follow the reverse procedure of removal with the following additional points:When installing the left axle shaft or the intermediate shaft on any model, push the axle shaft sharply inward to seat the retaining ring on the inner CV joint into the groove in the differential side gear.For the right axle shaft/intermediate shaft assembly, tighten the center bearing lock bolt to the specified torque.Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the correct torque.Tighten the axle shaft/hub nut to the specified torque, then install the nut lock and a new cotter pin.Check the transaxle lubricant (for manual transaxle) or differential lubricant (for automatic transaxle) and add if necessary to reach the proper level. Finally, check the intermediate shaft bearing for smooth operation and replace it if it feels rough or sticky.

To remove an axle shaft, start by disconnecting the cable from the negative terminal of the battery and setting the parking brake. Remove the wheel cover or hubcap, cotter pin, and bearing nut lock from the axle shaft hub nut. Loosen the front wheel lug nuts, raise the vehicle, and remove the wheel. Remove any engine splash shields in the way and the axle shaft/hub nut. Pry the control arm down to separate the components and tap the end of the axle shaft with a soft-faced hammer or a hammer and a brass punch to loosen it from the hub splines. Place a drain pan underneath the transaxle and remove the case protector if necessary. Pull out on the steering knuckle and detach the axle shaft from the hub. To install the axle shaft, follow the reverse of the removal procedure and push the axle shaft sharply inward to seat the retaining ring on the inner CV joint in the groove in the differential side gear. Check the intermediate shaft bearing for smooth operation and replace it if necessary.

Disconnect the cable from the negative terminal of the battery and set the parking brake.

Checking for wear in the CV joints and driveaxle shafts involves rotating each axle in both directions while feeling for play indicating worn splines or sloppy CV joints, as well as checking for cracks, dents, and distortion in the driveaxle shafts.

Symptoms of worn or damaged CV joints include clicking noises in turns, clunking when accelerating after coasting, and vibration at highway speeds.

The inner ends of the drive axles are directly splined to the differential side gears.

Power is transmitted from the transaxle to the wheels through a pair of driveaxles. The inner end of each driveaxle is connected to the transaxle, directly splined to the differential side gears. The outer ends of the driveaxles are splined to the axle hubs and locked in place by a large nut. The left side driveaxle is shorter while the right side driveaxle is longer and equipped with an intermediate shaft that is supported in the middle by a bearing support.

Loosen the front wheel lug nuts, raise the vehicle, and support it securely on jackstands. Then, remove the wheel.
