Toyota 43430-04070 Shaft Assembly, Front Drive, Left

Loosen the front wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands while blocking the rear wheels to prevent rolling. Remove the wheel(s) and drain the differential lubricant. Remove the grease cap by tapping it from the hub with a hammer and chisel. Take out the cotter pin and nut lock, then use a prybar or large screwdriver between the wheel studs to hold the axle shaft while loosening the axle shaft/hub nut with a large breaker bar, or have an assistant apply the brakes. Remove the ABS wheel speed sensor(s) and disconnect the outer tie rod ends from the steering knuckle. Unbolt the lower balljoint bracket from the steering knuckle. Knock the axle shaft loose from the steering knuckle using a brass drift and hammer, avoiding steel tools to prevent damage to the threads. Swing the steering knuckle outward and pull the axle shaft assembly out, detaching it from the differential; for the right axle shaft, tap the inner CV joint out with a hammer and brass drift, and for the left axle shaft, use a slide hammer with a special hooked adapter to pull the inner CV joint. Installation is the reverse of removal, ensuring to tighten the axle shaft/hub nut to the specified torque, then install the nut lock and a new cotter pin, followed by tightening the lug nuts and all suspension fasteners to the correct torque. Finally, refill the differential with the appropriate lubricant.

A thorough check of other possible causes should be conducted before concluding that the axle is the problem.

Equalize the pressure in the boot, then tighten and secure the boot clamps. To install the new clamps, bend the tang down, then tap the tabs over to hold it in place. If your replacement boot came with crimp-type clamps, a special tool will be required to tighten them properly.

Detach the vent hose from the axle housing.
