Lexus 43410-0W180 Shaft Assy, Front Drive, RH

Before starting this procedure, obtain a new axle shaft/hub nut. Begin by disconnecting the cable from the negative terminal of the battery. Loosen the front wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the wheel. Unstake and remove the axle shaft/hub nut, bracing a prybar between two wheel studs to prevent the hub from turning. Disconnect the stabilizer bar link at the suspension strut and the tie-rod end from the steering knuckle, then remove the nuts and bolt securing the balljoint to the control arm, prying the control arm down to separate the components. Disconnect the ABS wheel speed sensor from the steering knuckle and the ABS harness clamp at the suspension strut. To loosen the axle shaft from the hub splines, tap the end of the axle shaft with a soft-faced hammer or brass punch; if stuck, it may be necessary to remove the brake disc and use a two-jaw puller. Place a drain pan underneath the transaxle to catch any leaking lubricant. If applicable, remove the case protector over the inner CV joint. Pull out on the steering knuckle to detach the axle shaft from the hub, taking care to protect your hands from the sharp ring around the CV joint. For right axle shaft assemblies, remove the center bearing lock bolt and snap-ring, then pull the splined inner end of the intermediate shaft out of the differential side gear. For the left axle shaft, carefully pry the inner CV joint out of the transaxle. If necessary to move the vehicle while the axle shaft is out, place a large bolt with washers through the hub and tighten securely. Installation is the reverse of removal, ensuring to push the left axle shaft sharply inward to seat the retaining ring, tighten the center bearing lock bolt for the right axle shaft/intermediate shaft assembly, use a new axle shaft/hub nut and stake it, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts. Finally, check the transaxle lubricant and add if necessary, and check the intermediate shaft bearing for smooth operation, replacing it if it feels rough or sticky.

The most common symptoms of worn or damaged CV joints, besides lubricant leaks, include a clicking noise in turns, a clunk when accelerating after coasting, and vibration at highway speeds.
