Q. How is the rear axle removed?

A. Jack up car and remove rear wheels as instructed below. Take out the four bolts connecting the universal ball cap to the transmission case and cover. Disconnect brake rods. Remove nuts holding spring perches to rear axle housing flanges. Raise frame at the rear end, and the axle can be easily withdrawn.

Q. How is the universal joint disconnected from the drive shaft?

A. Remove two plugs from top and bottom of ball casting and turn shaft until pin comes opposite hole, drive out pin and joint can be pulled or forced away from the shaft and out of the housing.

Q. How are the rear axle and differential disassembled?

A. With the universal joint disconnected, remove nuts in front end of radius rods and the nuts on studs holding drive shaft tube to rear axle housing. Remove bolts which hold the two halves of differential together. If necessary to disassemble differential a very slight mechanical knowledge will permit one to immediately discern how to do it once it is exposed to view. Care must be exercised to get every pin, bolt and key lock back in its correct position when reassembling.

Q. How is the drive shaft pinion removed?

A. The end of the drive shaft, to which the pinion is attached, is tapered to fit the tapered hole in the pinion, which is keyed onto the shaft, and then secured by a cotter pinned “castle” nut. Remove the castle nut, and drive the pinion off.

Q. How are the differential gears removed?

A. The compensating gears are attached to the inner ends of the rear axle shaft. They work upon the spider gears when turning a corner, so that the axle shaft revolves independently, but when the car is moving in a straight line the spider gears and compensating gears and axle shaft move as an integral part. If you will examine the rear axle shafts you will notice that the gears are keyed on, and held in position by a ring which is in two halves and fits in a groove in the rear axle shaft. To remove the compensating gears, force them down on the shaft, that is, away from the end to which they are secured, drive out the two halves of ring in the grooves in shaft with screw driver or chisel, then force the gears off the end of the shafts.

Q. How is the rear axle shaft removed?

A. Disconnect rear axle as directed above, then unbolt the drive shaft assembly where it joins the rear axle housing at the differential. Disconnect the two radius rods at the outer end of the housing. Take out the bolts which hold the two halves of the rear axle housing together at the center. Take the inner differential casing apart and draw the axle shaft through the housing at the center. After replacing the axle shaft be sure that the rear wheels are firmly wedged on at the outer end of the axle shaft and the key in proper position. When the car has been driven thirty days or so, make it a point to remove the hub cap and set up the lock nut to overcome any play that might have developed. It is extremely important that the rear wheels are kept tight, otherwise the constant rocking back and forth against the key may in time cause serious trouble. If the rear axle or wheel is sprung by skidding against the curb, or other accident, it is false economy to drive the car, as tires, gears and all other parts will suffer. If the axle shaft is bent, it can, with proper facilities, be straightened, but it is best to replace it.
