To disconnect the rear axle without springs, you need to install the car on a flat horizontal platform or on an inspection ditch equipped with a lifting device

  • 1. Remove the shock absorbers by unscrewing the lower and upper fasteners. To avoid leakage of brake fluid from the system, it is allowed to pinch the hoses that supply brake fluid to the axle with a clamp.

Be careful not to damage the hoses, then disconnect the hoses from the bridge.

  • 2. Disconnect the cardan shaft.
  • 3. Release the parking brake cable by pulling out the rollers.

Remove the bolts securing the brake force regulator bracket to the axle.

Unscrew the nut securing the stabilizer pin to the bracket and knock the pin out of the bracket through a copper punch.

  • 4. Using a lifting mechanism, raise the rear of the vehicle so that the rear springs are released from the load. Place props under the axle gearbox.

Evenly unscrew the nuts of the stepladders for fastening the springs, raise the frame.

  • 5. Roll out the rear axle from under the frame, supporting the gearbox.

Lower the frame on the stands.

To disassemble the rear axle, do the following

  • 1. Remove the wheels, clean the bridge of dirt.

ZIL-5301 final drive

  • 2. Drain the oil.
  • 3. Remove axle shafts (see section "Adjusting bearing preload differential and backlash control in the final drive gear engagement”).
  • 4. Unscrew the locknut 39 (see Fig. 1), remove the lock ring. There are two threaded holes in the lock ring, as well as in the axle shaft flange, designed to facilitate their removal.

Unscrew the adjusting nut.

Wheel hub puller

In fig. 2 shows the removal of the wheel hubs using a puller installed with an annular grip on the wheel studs and secured with wheel nuts.

  • 5. Loosen the bolts securing the rear axle housing cover and remove it. Mark with a core the relative position of the bearing caps of the differential cups and the axle housing.

Unlock and unscrew the bolts securing the bearing caps. Remove covers.

Mark and remove both adjusting nuts, remove differential with bearings

  • 6. Unscrew the bolts securing the cup of the bearings of the drive gear, and then remove it. Remove shims 18 (see Fig. 1).
  • 7. Disassemble the glass (see .Contact adjustment in ZIL-5301 gears
  • 8. Using a mandrel, press the outer ring of the rear bearing out of the glass.

Remove the rear bearing from the drive bevel gear shaft

It is recommended to remove the rear bearing from the drive gear shaft with a puller 20P-7984 (Fig. 3).

  • 9. Loosen and unscrew the bolts securing the driven gear and remove it from the left differential cup using a copper mandrel and a hammer.

Mark the relative position of the differential cups with a core.

  • 10. Loosen the differential cup bolts.
  • 11. Remove the right cup and right axle gear with thrust washer. With a thin beard, push the pins of the pins of the satellites into the pin hole until they stop.

After that, you can press the pins of the satellites in any sequence with a beard and remove the satellites with support washers.

  • 12. Remove the left axle gear with thrust washer.

The bearing puller from the neck of the differential cup is similar in design to the bearing puller from the pinion shaft. In this case, the puller is installed so that the grips of the puller fit under the end face of the inner ring of the bearing.
