Lexus 43420-06170 Shaft Assy, Front Drive, LH

The power from the transaxle is transmitted to the wheels through a pair of axle shafts, with the inner end of each axle shaft directly splined to the differential side gears. The outer ends of the axle shafts are splined to the axle hubs and locked in place by a large nut. The left side axle shaft is shorter, while the right side axle shaft is longer and equipped with an intermediate shaft supported by a bearing support. The inner ends of the axle shafts have sliding constant velocity joints capable of both angular and axial motion, while the outer joints are capable of angular but not axial movement. The boots should be inspected periodically for damage and leaks, and torn CV Boot must be replaced immediately to prevent damage. Symptoms of worn or damaged CV joints include clicking noises in turns, clunking when accelerating after coasting, and vibration at highway speeds. Checking for wear in the CV joints and axle 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 axle shafts.
