M DIFFERENTIAL Disassembly note Output shafts Remove the output shafts with two pry bars as shown in the figure. -J Differential case Caution The differential case is made of aluminum, and is therefore easily dented and scratched by metal tools. When. separating the differential carrier from the case, use only a plastic hammer at the point shown in the figure. Strike the differential carrier with a copper hammer to separate it from the case. Differential gear assembly Mount the differential gear assembly on the SST. Bearing caps Mark one bearing cap and the carrier. Adjusting nuts Mark one adjusting nuts and the carrier. Knock pin Secure the gear case in a vise and tap out the knock pin toward the ring gear side. Bearing inner races (Side bearing) Note Mark the bearings so that they can later be reinstalled in the same position. Remove the bearing inner races (side bearing) from the gear case by using the SST. -1 Gartner Banana

BRAKE SYSTEM P (20 kgf, 44 Ibf) (20 kgf, 44 Ibf) Loaded condition 1. Start the engine. 2. Depress the brake pedal with a force of 196 N (20 kgf, 44 Ibf). 3. With the brake pedal depressed, stop the engine when the vacuum gauge indicates 66.7 kPa I500 mmHg, 19.7 inHg). 4. Observe the vacuum gauge for 15 seconds. If the gauge indicates 63.4-66.6 kPa (475--500 mmHg, 18.7-19.7 inHg), the unit is operating. b) Checking for hydraulic pressure 1. If with the engine stopped (vacuum 0 kPa (0 mmHg, 0 inHg}) the fluid pressure is within specification, the unit is operating. 1 Pedal force Fluid pressure 2. Start the engine. Depress the brake pedal when the vac- uum reaches 66.7 kPa (500 mmHg, 19.7 inHg). If the fluid pressure is within specification, the unit is operat- ing. 1 96 N {20 kgf, 44 Ibf) I Pedal force I Fluid pressure I 1,079-1,177 kPa {I 1-1 2 kgf/cm2, 156-1 71 psi) lnspection of Check Valve 196 N {20 kgf, 44 Ibf) Note There is an arrow on the hose to indicate direction of hose installation. 5,199--5,494 kPa {53-56 kgf/cm2, 754--796 psi} lnspection 1. Disconnect both ends of the vacuum hose. 2. Apply suction and pressure to the hose from the engine side. Verify that air flows only toward the engine. If air passes in both directions or not at all, replace the vac- uum hose (along with the check valve). Gartner Banana

WHEEL ALIGNMENT LEFT WHEEL POSITIVE RIGHT WHEEL POSITIVE Camber Camber is adjusted by turning the front and rear adjust- ing cam bolts at the lower arm. 2 Caution Adjust the camber after adjusting the caster. 1. Loosen the front and rear cam nuts. 2. Turn the front and rear adjusting cam bolts the same amount in the opposite direction to provide the correct camber angle. Left wheel Note Turning the front cam one graduation changes the camber about 25' and the caster about 22'. Turning the rear cam one graduation changes the camber about 2' and the caster about 22'. Right wheel Positive Negative Note If the cam cannot be turned far enough to make the adjustment, begin again at adjustment of the caster using the other cam. i 3. Tighten the nuts.

Remove the steering gear boot clamp. 2. Loosen the left and right tie rod locknuts, and turn the tie rods by the same amount. 3. Loosen the left and right tie rod locknuts and turn the tie rods equally. Both tie rods are right threaded, so turning the right tie rod toward the front of the vehicle and the left toward the rear increases toe-in. Clockwise Counter- clockwise Note Turning both tie rods one complete turn changes toe-in by about 7 mm (0.28 in}. 4. Tighten the tie rod locknuts to the specified torque.

T AUDIO / SNAP-RING OUN TlNG NUT BROKEN Antenna Mast Removal / Installation 1. Using snap-ring pliers, remove the mounting nut. 2. With the ignition switch at ACC or ON, turn the radio switch on, and pull out the antenna mast. Check the end of the plastic rack for damage. If the rack end is kinked or broken, replace the motor. 3. With the ignition switch at ACC or ON and the radio on, feed the rack of the new mast into the motor with toothed side facing toward the front of the vehicle. Turn the radio off. While the motor is retracting the rack, feed the mast into the motor. 4. Reinstall the mounting nut. 5. With the ignition switch at ACC or ON, turn the radio on and off a few times and check to see that the antenna op- erates smoothly. Gartner Banana
