Install the subframe bolt retainers (D). Tighten the two flange bolts (E) and nuts (F) to the specified torque.






13. Install the front subframe front brackets (A) with 12 mm flange bolts (B) and the new 14 mm special bolts (C), and tighten to the specified torque.





14. Remove the jack from the subframe adapter.

15. Install the front splash shield Front Splash Shield Replacement.

16. Install the No.1 propeller shaft protector (A).






17. Connect the power steering pressure (PSP) switch connector (A).






18. Connect the under-floor three way catalytic converter (TWC) (A) to the muffler (B). Install the new 10 mm self-locking nuts and tighten them to the specified torque.






19. Install the front subframe stiffener (A) and tighten to the specified torque.






20. Install the new 10 mm flange bolts on the engine side mount bracket (A).





21. Remove the engine support hanger, the hanger balance bar, and the hanger adapter set.

22. Install the connector bracket (A) to the front cylinder head.






23. Install the harness clamp bracket (A) to the rear cylinder head.





24. Install the service caps on the cowl cover.

25. Install the power steering pump outlet line (A) with a new O-ring (B) to the pump, and secure the hose clamp (C) with the bolt.






26. Wipe off any grease contamination from the ball joint tapered section and threads. Reconnect the tie-rod ends (A) to the steering knuckles. Install the 12 mm nut (B) and tighten it on both sides.





27. Install a new cotter pin (C) and bend it as shown on both sides.

28. Center the steering rack within its stroke.

29. Insert the upper end of the steering joint onto the steering shaft (A) (line up the bolt hole (B) with the flat portion (C) on the shaft), and loosely install the upper joint bolt (D).





30. Slip the lower end of the steering joint onto the pinion shaft taking care to align the gap (E) within the angle.

31. Align the bolt hole (A) on the steering joint with the groove (B) around the pinion shaft, then loosely install the lower steering joint bolt (C). Be sure that the joint bolt is securely in the groove in the pinion shaft.





32. Pull on the steering joint to make sure that the steering joint is fully seated, then tighten the lower joint bolt to the specified torque.

33. Tighten the upper steering joint bolt (D) to the specified torque.

34. Install steering joint cover (A).





35. Install the front wheel, then set the wheels in the straight ahead position.

NOTE: Before installing the wheel, clean the mating surfaces of the brake disc and the inside of the wheel.

36. Install the steering wheel Steering Wheel Installation.

37. Do the battery terminal reconnection procedure Procedures, and check these items:

- Turn the ignition switch to ON (II) and check that the SRS indicator comes on for about 6 seconds and then goes off.
- Make sure the horn and turn signal switches work properly.
- Make sure the steering wheel switches work properly.

38. Fill the system with power steering fluid, and bleed air from the system Service and Repair.

39. After installation, check these items:

- Start the engine, allow it to idle, and turn the steering wheel from lock to lock several times to warm up the fluid. Check the gearbox for leaks Hydraulic Power Steering Fluid Leakage Inspection.
- Do the front toe inspection Service and Repair.
- Check the steering wheel spoke angle.
If steering spoke angles to the right and left are not equal (steering wheel and rack are not centered), correct the engagement of the joint/pinion shaft serrations, then adjust the front toe by turning the tie-rod ends, if necessary.
