(d) Measure the front hub bearing's starting torque.

Put the SST on the wheel bolts which are at the symmetric

locations. Put a dial torque wrench on the SST to slowly

rotate the flange assembly (45°/4s), requiring a starting

torque range of 0.1-0.3 N·m.

If the bearing rotation is not flexible, the front hub flange

plate surface movement inaccurate, or front hub bearing

starting torque is too much. The assembly must be replaced.

1. Removal and inspection of front hub flange assembly.

(a) Use SST like a hand held travel hammer to repeatedly

hammer off the front hub flange assembly from the

steering knuckle and front hub bearing. Remove the

front hub with bearing's inner ring.

(b) Remove the bearing's inner ring on the front hub.

Use SST to remove the bearing's inner ring.

(c) Use dye penetrant to inspect the front hub flange for

cracks, which should be replaced if found.

(d) If one would like to continue using the front hub flange

assembly, first inspect the dimensions for the mounting

area of the bearing for inaccurate dimensions. If

oversized, replace.

2. Remove the steering knuckle's front hub bearing.

3. Remove the snap ring for hole 72.

Use a bent nose retaining ring caliper for holes to remove the

snap ring for hole 72.

4. Replace the removed bearing's inner ring back to the

bearing's original position.

5. Press out the front hub bearing from inside of the steer-

ing knuckle.

On the press, withstand the bearing inner ring that was put

on with SST, and press out the entire front hub bearing.

Caution: The front hub bearing assembly is a disposable

part, which needs to be replaced with a new one.

1. On the press, press the front hub bearing assembly

into the steering knuckle hole bearing mounting posi-

tion with SST.

6. If the steering knuckle has no cracks and one would

like to continue to use it, first inspect the bearing's

mounting location dimensions of the steering knuckle's

inner hole. If the measurements are oversized, replace

the steering knuckle.

2. Press the front hub flange assembly.

On the press, press the front hub flange into the front hub

bearing mounting position using SST.

3. Examine the front hub flange plate surface runout.

Examining methods are the same as the methods used

during disassembly. Plate surface runout should not exceed

0.03 mm.

4. Examine the front hub bearing assembly's starting

torque.

Examining methods are the same as the methods used during

disassembly. Put the SST on the wheel bolts which are at the

symmetrical locations. Put a dial torque wrench on the SST to

slowly rotate the flange's flange assembly (45°/4s), which re-

quires a starting torque range of 0.1-0.3 N·m

5. Install the snap ring for hole 72.

Use a bent nose retaining ring caliper for holes to install the

snap ring for hole 72 at the steering knuckle's retaining ring

mounting position.

6. Install the steering knuckle's front hub bearing and

front hub flange assembly.

7. Install the front brake disc cover.

Install the front brake disc cover on the steering knuckle, and

tighten the bolt to the set torque.

Tightening torque: 9±2 N·m

9. Examine the front brake disc plate surface runout.

When measuring, tighten the two wheel nut's symmetrical

locations. The front brake disc's brake linings runout on the

two sides should be less than 0.11 mm.

10. Install the brake caliper assembly.

Install the brake caliper on the steering knuckle, and tighten

the bolt according to the set torque.

Tightening torque: 100±10 N·m
