Steering Gear

The first step for removing the power rack and pinion from a sedan involves positioning the front wheels straight ahead then disconnecting the negative terminal battery cable. As the second step you should take out the 4 bolts which hold the hood in place. The first step requires removing the front wiper arm head caps then continuing with front wiper arm and blade assemblies from both left and right sides. For removal of the power rack and pinion you need to take away both cowl side ventilator sub-assemblies together with cowl top ventilator louver sub-assembly and front wiper motor and link. Process next by taking off the front air shutter seal and then detach the cowl top panel outer. Remove the column hole cover silencer sheet by unfastening the floor carpet and its 2 clips. Properly secure the steering wheel assembly using a seat belt to keep the spiral cable safe and mark the sliding yoke of the steering intermediate shaft assembly and power rack and pinion before unbolt A and unfasten B to separate the steering intermediate shaft assembly. The process to remove the No. 1 steering column hole cover sub-assembly requires unfastening clip A and peeling clip B off its body attachment. Begin by removing the front wheel and proceeding with removal of both tie rod end sub-assemblies and front stabilizer link assemblies and front suspension lower arms from both sides. Engine suspension will start with removing the radio setting condenser connection bolt and the air-fuel ratio sensor wiring bracket. The suspension process requires using engine hanger (Part No.: 12281-21010) installed with bolt (Part No.: 91642-81025) torqued to 40 Nm (408 kgf-cm, 30 ft-lbf). An engine sling device and chain block sustain the engine assembly while technicians follow steps to eliminate the front suspension crossmember sub-assembly by loosening the engine moving control rod then using a transmission jack to stabilize the crossmember followed by removing the 6 bolts. You can remove the power rack and pinion after taking out the 2 bolts and 2 nuts making sure the nuts stay still throughout the operation.

Remove the front wiper arm head cap, followed by the left and right front wiper arm and blade assemblies, and then the left and right cowl side ventilator sub-assemblies.

Place matchmarks on the sliding yoke of the steering intermediate shaft assembly and the power steering.

Fix the steering wheel assembly with a seat belt to prevent damage to the spiral cable.

Take out the 2 bolts and 2 nuts while ensuring the nut does not rotate.
