Scheme 26

1. Suspend the brake caliper component using a cable or equivalent.
2. Temporarily tighten the wheel nut to prevent the disc plate from falling off.

Scheme 27

1. Insert a tire lever or equivalent between the rear differential and differential side outer ring, and remove the rear drive shaft. CAUTION: The sharp edges of the drive shaft can slice or puncture the oil seal. Be careful not to damage the oil seal when removing the drive shaft from the differential.
2. Pull the rear drive shaft and rear knuckle component to the outer side, and detach the rear drive shaft from the rear differential.
3. To hold the rear drive shaft and rear knuckle component, install the rear lateral link (upper) to the rear knuckle temporarily after disconnecting the rear drive shaft.

Scheme 28

Scheme 29

1. Support the transmission using a transmission jack.
2. Remove the power plant frame.

Scheme 30

1. Remove the rear differential, while supporting it securely with a jack, and moving the jack gradually.

Scheme 31

Scheme 32

Scheme 33

Scheme 34

1. Support the rear differential using the jack.
2. Temporarily tighten the differential mounting installation bolts.
3. Support the transmission and differential so that they are level using a transmission jack.
4. Install the power plant frame.
5. Temporarily tighten the nuts 1, 2, 3 in order shown in illustration.
6. Tighten nut 2 until the power plant frame is seated in the rear differential.
7. Temporarily tighten the nuts 4, 5 in order shown in illustration.
8. Install the tunnel member (MT) or tunnel member component (AT). (See «TRANSMISSION REMOVAL/INSTALLATION [M15M-D]»(ref-430321-S20208983802011101700000) ) (See «TRANSMISSION REMOVAL/INSTALLATION [P66M-D]»(ref-430322-S39125528952011101700000) ) (See «AUTOMATIC TRANSMISSION REMOVAL/INSTALLATION [SJ6A-EL]»(ref-430333-S25457889692011101700000) )
9. Raise the front end of the power plant frame (transmission side) or the transmission with the transmission jack, and adjust dimension A to 26.7-34.7 mm {1.06-1.36 in} (lower surface of power plant frame-upper surface of the tunnel member) as shown in illustration. NOTE: If there is the possibility of age-related bending/deterioration of the mount, adjust dimension A to approx. 15 mm {0.59 in} higher than the adjustment value to facilitate obtaining the specification.
10. Tighten the power plant frame installation nuts. Tightening Torque: 126-154 N.m {12.9-15.7 kgf.m, 93.0-113.5 ft.lbf}
11. Verify that dimension A is within the specification with the transmission jack and the adjustment bolt removed. If not within the specification, adjust dimension A again. Standard dimension A 26.7-34.7 mm {1.06-1.36 in}
12. Remove the tunnel member (MT) or tunnel member component (AT).
13. Temporarily loosen the differential mounting installation bolts, straighten the differential mounting bracket bushings, and then tighten the differential mounting installation bolts again to the specified torque. CAUTION: Never support the rear differential using a jack when tightening the differential mounting installation bolts. Otherwise, the differential mounting bracket bushings will twist and cause an abnormal noise while the vehicle is moving. Tightening Torque: 74.5-105.0 N.m {7.60-10.70 kgf.m, 55.0-77.44 ft.lbf}

Scheme 35

1. Install a new drive shaft clip to the clip groove at the top of the rear drive shaft with the clip opening facing upward and the clip width within the specification. Standard 31.2 mm {1.23 in}
2. After installing the clip, measure the outer diametric if it exceeds the specification, reinstall a new clip.
3. Apply differential oil to the differential oil seal lip. CAUTION: The sharp edges of the rear drive shaft can slice or puncture the oil seal Be careful not to damage the oil seal when installing the rear drive shaft from the rear differential.
4. Insert the rear drive shaft into the rear differential with the clip opening facing upward.
5. After installation, verify that the rear drive shaft is securely held by the clip by pulling the outer ring on the differential side towards the axle.
