GM 26079789 Front Wheel Drive Shaft Kit

Power is transmitted from the front differential/axle to the front wheels through a pair of driveaxles, with the inner end of the right driveaxle splined to an axleshaft connected to the right differential side gear, while the inner end of the left driveaxle has a short stub shaft splined to the left differential side gear. The outer end of each driveaxle features a stub shaft splined to the front hub and bearing assembly, secured with a large nut. The inner ends of the driveaxles are equipped with sliding constant velocity (CV) joints, allowing for both angular and axial motion, consisting of a tripot-type bearing and a housing that permits sliding as the driveaxle moves with the wheel. The outer ends are fitted with "ball-and-cage" type CV joints, which allow for angular movement but not axial, comprising six caged ball bearings between an inner race and the housing. Periodic inspection of the boots for damage and leaking lubricant is essential, as torn CV joint boots must be replaced immediately to prevent joint damage; if a boot is damaged, the driveaxle must be removed for replacement. In cases of boot damage, the CV joint can be disassembled and cleaned, but any damaged parts necessitate replacement of the entire driveaxle assembly. Common symptoms of worn or damaged CV joints include lubricant leaks, a clicking noise during turns, a clunk when accelerating after coasting, and vibration at highway speeds. To check for wear, grasp each axle individually and rotate it in both directions while holding the CV joint housings, feeling for play that indicates worn splines or sloppy CV joints, and inspect the driveaxle shafts for cracks, dents, and distortion.

No, the hub nut should not be reused, so install a new one when putting the shaft back.

Common noises include road noise, tire noise from worn or under-inflated tires, and engine or transmission noise.

For models with a conventional differential, remove the pinion shaft.

Lower the jack under the differential and remove the rear axle assembly from under the vehicle.
