Power is transmitted from the transaxle to the wheels through a pair of axle shafts. The inner end of each axle shaft is splined to the differential. The outer ends of the axle shafts are splined to the axle hubs and locked in place by an axle nut. The inner ends of the axle shafts are equipped with sliding double offset joints (1994 and earlier) or tri-pot joints (1995 and later), which are capable of both angular and axial motion. Each inner joint assembly consists of an inner race, ball bearing and cage assembly (double offset joint) or a tri-pot spider bearing assembly (1995 and later models) and an outer race (housing) in which the inner bearing assembly is free to slide in and out as the axle shaft moves up and down with the wheel. The inner joints are replaceable. Each outer joint, which consists of ball bearings running between an inner race and an outer cage, is capable of angular but not axial movement. The outer joints are neither rebuildable nor removable. Should one of them fail, a new axle shaft/outer joint assembly must be installed. The boots should be periodically inspected for damage, leaking lubricant and cuts. Damaged CV joint boots must be replaced immediately or the joints can be damaged. Boot replacement involves removal of the axle shaft. Note: Some auto parts stores carry "split" type replacement boots, which can be installed without removing the axle shaft from the vehicle. This is a convenient alternative; however, it's recommended that the axle shaft be removed and the CV joint disassembled and cleaned to ensure that the joint is free from contaminants such as moisture and dirt, which will accelerate CV joint wear. The most common symptom of worn or damaged CV joints, besides lubricant leaks, is a clicking noise in tums, a clunk when accelerating from a coasting condition or vibration at highway speeds. To check for wear in the CV joints and axle shafts, grasp each axle (one at a time) and rotate it in both directions while holding the CV joint housings, inspecting for movement, indicating worn or damaged CV joints. Also check the axle shafts for cracks, dents, twisting and bending.

To remove the driveaxle hub nut, brace a screwdriver across two of the wheel studs and loosen the hub nut.
