  A: Begin the front shock absorber with coil spring service and repair task by taking off the front wheel and wiper arm head cap and both front wiper arms before handling the hood to cowl top seal and left-hand side cowl top ventilator louver. Use a jack to support the front No. 1 suspension lower arm LH before removing the stabilizer link nut while disconnecting the assembly from the left-hand side. The front speed sensor LH requires complete disconnection from the shock absorber assembly by removing its bolt. Loosen the lock nut on the front shock absorber housing except for complete removal before removing its two lower nuts and three upper nuts which will retain all bolts. Slower movement of the jack allows you to remove the shock absorber from its position. You should first clamp the shock absorber in a vise and then remove the lock nut using Special Service Tool: 09727-30021 before you proceed to take off one by one the dust seal and suspension support LH followed by the coil spring seat upper LH, coil spring insulator upper LH, coil spring LH, spring bumper LH, and coil spring insulator lower LH.

After installing the front speed sensor LH and stabilizer link assembly LH (torque: 74 Nm), the technician should fasten the front wheel (torque: 103 Nm) but should start installation with the cowl top ventilator louver and then proceed to attach the hood to cowl top seal and both front wiper arms and head cap. Examine and correct the front wheel alignment at the end of the procedure. emporary disposal of the shock absorber requires a piston rod extension before drilling a hole into the cylinder to release gas while using appropriate protective equipment.
