  • DESCRIPTION The axle consists of an alumunum center section with an axle tube extending from one side. The tube is pressed into the differential housing. The power is transferred from the axle through two constant velocity (C/V) drive shafts to the wheel hubs. The drive shafts are identical and interchangeable. OPERATION The axle receives power from the propeller shaft. The propeller shaft is connected to the pinion gear which rotates the differential through the gear mesh with the ring gear bolted to the differential case.
  • The engine power is transmitted to the axle shafts through the pinion mate and side gears. The side gears are splined to the axle shafts. DIAGNOSIS AND TESTING GEAR NOISE Axle gear noise can be caused by insufficient lubricant, incorrect backlash, tooth contact, worn/damaged gears or the carrier housing not having the proper offset and squareness. Gear noise usually happens at a specific speed range. The noise can also occur during a specific type of driving condition. These conditions are acceleration, deceleration, coast, or constant load.
  • When road testing, first warm-up the axle fluid by driving the vehicle at least 5 miles and then accelerate the vehicle to the speed range where the noise is the greatest. Shift out-of-gear and coast through the peak-noise range. If the noise stops or changes greatly: ² Check for insufficient lubricant. ² Incorrect ring gear backlash. ² Gear damage. Differential side gears and pinions can be checked by turning the vehicle.
  • They usually do not cause noise during straight-ahead driving when the gears are unloaded. The side gears are loaded during vehicle turns. A worn pinion mate shaft can also cause a snapping or a knocking noise. BEARING NOISE The axle shaft, differential and pinion bearings can all produce noise when worn or damaged.
  • Bearing noise can be either a whining, or a growling sound. Pinion bearings have a constant-pitch noise. This noise changes only with vehicle speed. Pinion bearing noise will be higher pitched because it rotates at a faster rate.
  • Drive the vehicle and load the differential. If bearing noise occurs, the rear pinion bearing is the source of the noise. If the bearing noise is heard during a coast, the front pinion bearing is the source. Worn or damaged differential bearings usually produce a low pitch noise. Differential bearing noise is similar to pinion bearing noise.
