Before installing the wheel and parts of the brake system, check the torque of the hub. Hook the dynamometer to the hub bolt and measure the torque at a frequency of 10±2 rpm.
- Torque: less than 1,750 Nm (0.178 kgm)
- Dynamometer reading: less than 30.6 N (3.10 kg)
Tighten the trailing arm bracket mounting bolts in the order shown in fig.
Attention: Tighten bolt 1 by hand, tighten bolts 2, 3 and 4 to the required torque. Then tighten bolt 1.
After installation, make the final tightening of bolts and nuts on an unladen vehicle with tires on the ground. Check wheel alignment and bleed air from brake system.
When installing the brake pipe bracket, do not deform it.
Pay attention to the following when installing the spring.
