Rear Axle Beam (For Sedan) Installation

Align the matchmarks on a new bush and the axle beam and provisionally install the bush onto the axle beam, as shown in the illustration.

NOTICE:

Install the bush in the same orientation as the old one was prior to removal because they are directional.

Using SST, install the bush onto the axle beam.

NOTICE:

Do not damage the rubber portion when installing the bush.

Support the rear axle beam with a jack.

Install the axle beam onto the vehicle and provisionally tighten the 2 bolts.

Install the coil spring insulator lower onto the axle beam.

Install the coil spring insulator upper so that its gap fits onto the end of coil spring.

Install the coil spring onto the axle beam.

NOTICE:

The paint mark of the coil spring should be towards the underside and rear side of the vehicle.

Support the axle beam with a jack. Insert a wooden block between the jack and the rear axle spring seat to prevent damage.

Jack up the axle beam slowly, and provisionally tighten the shock absorber (lower side) with the bolt and nut to the axle beam.

Install the suspension support and cushion retainer.

While holding the piston rod, install a new nut (lower nut) to the specified standard.

Standard:

15 to 18 mm (0.591 to 0.709 in.)

Hold the lower nut and tighten the upper nut against it.

Torque:

25 N*m{250 kgf*cm, 18 ft.*lbf}

Install the axle hub and bearing onto the axle beam with the 4 bolts.

Torque:

90 N*m{918 kgf*cm, 67 ft.*lbf}

Inspect the axle hub and bearing backlash.

1. Using a dial indicator, check the backlash near the center of the axle hub.
   

   Maximum:

   0.05 mm (0.0020 in.)
   

   If the backlash exceeds the maximum, replace the axle hub and bearing.
   

Inspect the axle hub and bearing runout.

1. Using a dial indicator, check the runout of the surface of the axle hub.
   

   Maximum:

   0.07 mm (0.0028 in.)
   

   If the runout exceeds the maximum, replace the axle hub and bearing.
   

Provisionally install the 2 hub nuts.

Remove the hole plug, and turn the adjuster to expand the shoe until the drum locks.

Using a screwdriver, release the adjuster 12 notches.

Install the hole plug.

Install the parking brake cable with the bolt and a new clamp.

Torque:

6.0 N*m{61 kgf*cm, 53 in.*lbf}

Install the brake tube onto the axle beam with the nut.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Connect the flexible hose to the axle beam with a new clip.

Using a union nut wrench (10 mm), separate the brake tube while holding the flexible hose with a wrench.

Torque:

15 N*m{155 kgf*cm, 11 ft.*lbf}

NOTICE:

Use the formula to calculate special torque values for situations where the union nut wrench is combined with a torque wrench (YARIS_NCP93 RM000000UYX0BYX.html).

Install the skid control sensor wire onto the axle beam with the nut.

Torque:

6.0 N*m{61 kgf*cm, 53 in.*lbf}

Connect the skid control sensor wire connector.

Lower the vehicle from the jack.

Bounce the vehicle up and down several times to stabilize the suspension.

Suspend the jack on the rear axle spring seat and adjust the length of the shock absorber to the reference value.

Length of shock absorber:

220 mm (8.66 in.)

Fully tighten the 2 bolts.

Torque:

90 N*m{918 kgf*cm, 67 ft.*lbf}

Fully tighten the shock absorber (lower side) with the bolt.

Torque:

49 N*m{500 kgf*cm, 36 ft.*lbf}

Engage the 3 hooks and install the rear seatback.

Tighten the 3 bolts.

Torque:

7.9 N*m{80 kgf*cm, 70 in.*lbf}

Install the rear seat outer belt into the rear seat shoulder belt guide.

HINT:

Use the same procedure for both sides.

Install the rear center seat outer belt into the rear center seat shoulder belt guide.

Pass the rear seat inner belt through the rear seat cushion cover pad slit.

Engage the 3 hooks and install the rear seat cushion cover pad.

NOTICE:

Make sure that the 2 rear seat cushion lock hooks and the rear seat cushion frame are securely engaged.

Disengage the 3 clips and separate the hood to cowl top seal.

Remove the cowl top ventilator louver.

Set the brake fluid can upside down on the reservoir.

Fluid:

SAE J1703 or FMVSS No. 116 DOT3

Using a union nut wrench, disconnect the brake tubes from the master cylinder.

Slowly depress the brake pedal and hold it there (Step A).

Block the outer holes with your fingers, and release the brake pedal (Step B).

Repeat step A and B 3 or 4 times.

Using a union nut wrench, connect the brake tubes to the master cylinder.

Torque:

without union nut wrench:

15 N*m{155 kgf*cm, 11 ft.*lbf}

with union nut wrench:

14 N*m{144 kgf*cm, 10 ft.*lbf}

HINT:

1. This torque value can be obtained by using a torque wrench with a fulcrum length of 300 mm (11.8 in.) and a union nut wrench with a fulcrum length of 22 mm (0.866 in.) (YARIS_NCP93 RM000000UYX0BYX.html).
   
2. This torque value is effective when the union nut wrench is parallel to the torque wrench.
   

Connect the vinyl tube to the bleeder plug.

Depress the brake pedal several times, then loosen the bleeder plug with the pedal depressed (Step C).

At the point where the fluid stops coming out, tighten the bleeder plug, then release the brake pedal (Step D).

Repeat step C and D until all the air in the fluid is completely bled out.

Tighten the bleeder plug.

Torque:

8.3 N*m{85 kgf*cm, 73 in.*lbf}

Repeat the above procedure to bleed the air out of the brake line for each wheel.

Check the fluid level and add fluid if necessary.

Fluid:

SAE J1703 or FMVSS No. 116 DOT3
