What is the function of the axle shafts equipped with sliding constant velocity joints in transmitting power from the front differential/axle to the front wheels on GMC Sierra?

Power is transmitted from the front differential/axle to the front wheels through a pair of axle shafts equipped with sliding constant velocity (CV) joints capable of both angular and axial motion. The inner ends of the axle shafts are bolted to an axleshaft connected to the differential side gears, while the outer ends have a stub shaft that is splined to the front hub and bearing assembly and locked in place with a large nut. The outer ends of the axle shafts are equipped with ball-and-cage type CV joints capable of angular but not axial movement. It is important to inspect the boots periodically for damage and leaking lubricant, as torn CV joint boots must be replaced immediately to prevent damage to the joints. If a boot is damaged, the CV joint can be disassembled and cleaned, but if any parts are damaged, the entire axle shaft assembly must be replaced as a unit. Symptoms of worn or damaged CV joints include lubricant leaks, clicking noise in turns, 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. It is also important to check the axle shafts for cracks, dents, and distortion.

GMC Sierra Axle Shaft

The Axle Shaft used in GMC Sierra is designed for transmitting power from the differential towards the drive wheels to allow independent rotation for better tractions while at corners. These type of shafts are usually built from steel and are used in pairs where they help to bear the load from the vehicle, transmit the torque and ensure that the position of the wheels is correct. Several types of axels have been used at Sierra in models having live axles that provide support and help transmit weight and torque back to the vehicle, and non-driving axles used for suspension. The Sierra can include a straight axle for a higher degree of strength or a split axle for a smoother ride. Moreover, there are full-floating axle where the duty call responds through the axle casing and not the axle shaft as in the semi-floating design. In all, for proper performance specifically on GMC Sierra trucks, Axle Shaft is significantly vital to their handling.

Each OEM GMC Sierra Axle Shaft we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: What is the function of the axle shafts equipped with sliding constant velocity joints in transmitting power from the front differential/axle to the front wheels on GMC Sierra?
A: Power is transmitted from the front Differential/axle to the front wheels through a pair of axle shafts equipped with sliding constant velocity (CV) joints capable of both angular and axial motion. The inner ends of the axle shafts are bolted to an axleshaft connected to the differential side gears, while the outer ends have a stub shaft that is splined to the front hub and bearing assembly and locked in place with a large nut. The outer ends of the axle shafts are equipped with ball-and-cage type CV joints capable of angular but not axial movement. It is important to inspect the boots periodically for damage and leaking lubricant, as torn CV joint boots must be replaced immediately to prevent damage to the joints. If a boot is damaged, the CV joint can be disassembled and cleaned, but if any parts are damaged, the entire axle shaft assembly must be replaced as a unit. Symptoms of worn or damaged CV joints include lubricant leaks, clicking noise in turns, 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. It is also important to check the axle shafts for cracks, dents, and distortion.
