After unscrewing the bolts, the shock absorber will no longer hold the rear axle, and the spring will push it down, causing oil to flow. To avoid this, you need to first adjust the stand by jacking the car higher.

Pay attention to the groovers: If you ignore the loss of the groover and install a new one, the old one will subsequently get between the block and the drum while driving and the wheel will jam. After unscrewing the bolts, with a sharp movement, remove the axle shaft with the bearing from the cage.

If this fails, attach the wheel to the studs with 3 nuts and try to pull it. The last option is to use a special inertial puller for removal.

There is also a popular way: This will lead to problems with work efficiency. If it is necessary to change the type of lubricant, it is recommended to first flush the system.

When removing the axle shaft, oil will begin to flow out.

pliers;
hammer;
large flat screwdriver;
a powerful wrench for unscrewing and tightening the nut on the shank;

Signs of malfunction and wear of the rear axle bearing of Niva Chevrolet

As was said at the beginning of the article, radial and axial loads are concentrated on the axle bearing of the rear axle of the Niva Chevrolet. Since the ball bearing itself is radial, this means that axial loads should be minimal or absent, but they appear if there is play in the inner race along the seating surface. Play also appears inside the bearing itself when the raceway, balls, and cage wear out.

Other causes of failure: - Wear and leakage of the oil seal; — Ingress of dirt and moisture; — Shaft runout; — Movement of the locking (locking) faceplate along the shaft journal, resulting in play at the bearing; — Shaft imbalance.
