REMOVAL & INSTALLATION

Front

3000GT

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Disconnect the negative battery cable.
3. Raise and safely support vehicle.
4. Remove the brake hose and tube bracket. Do not pry the brake hose and tube clamp away when removing it.
5. If equipped with ABS, disconnect the front speed sensor mounting clamp from the strut.
6. Support the lower arm and remove the strut to knuckle bolts. Use a piece of wire to suspend the knuckle to keep the weight off the brake hose.
7. If equipped with Active Electronic Control Suspension (Active-ECS) perform the following:
   1. Loosen the nut that secures the air line to the to the top of the strut and discard the O-ring.
   2. Remove the bolts that secure the actuator to the top of the strut and remove the component. Disconnect the wiring harness.
8. Before removing the top bolts, make matchmarks on the body and the strut insulator for proper reassembly.
9. Remove the strut upper bolts and remove the strut assembly from the vehicle.
10. Compress the coil spring using a spring compressor until the spring just comes away from one of the seats.
11. Remove or disconnect the following:
    • Center nut from the strut and remove the upper mounting bracket and bushings
    • Coil spring

    To install:

12. Install or connect the following:
    • Compressed spring on the strut assembly
    • Upper bushings and the mounting bracket
    • Nut and tighten it to 16 ft. lbs. (22 Nm)
    • Strut to the vehicle and install the top bolts
    • Strut to the knuckle and install the bolts
13. If equipped with Active-ECS, perform the following:
    1. Install the air line with a new O-ring.
    2. Install the actuator to the top of the strut. Connect the wiring harness.
14. Install or connect the following:
    • Brake hose bracket and the ABS clamp
    • Wheel and tire assembly
    • Negative battery cable
15. Perform a front end alignment.
