Power Steering System - Fluid Level and Lines
2. The fluid level is checked with the engine cold and not running. The fluid level should be between the marks "Max" And "Min" on the tank body.
3. If refueling is necessary, clean the area around the reservoir cap and unscrew it. Add fluid to the level "Max" (photo). Replace the cover.
2.3. When refilling the brake system, use only good quality fluid of the specified type
4. Inspect every metal pipe and flexible hoses from the fuel tank, power steering pump and steering gear.
5. To check the lower pressure of the system, start the engine, turn the steering wheel from lock to lock until the fluid warms up (60-80°C). Set the idle speed, hold the steering wheel for no more than 5 seconds in each extreme position and carefully check for leaks.
6. If there are leaks, they must be repaired.
Power Steering System - Drive Belt
7. Check the condition and tension of the power steering and drive belt.
Checking the steering gear and communication
8. Apply the handbrake and raise the front of the car.
9. Visually inspect the steering gear protective rubber covers and rubber dust caps on the tie rods and outer ball joints.
10. On vehicles with direct steering, the steering shock absorber must be securely fastened.
11. The lower steering column pinch bolts should be tightened, the steering gear mounting bolts should be securely fastened, the outer tie rod ball joint lock nuts should be tightened, with the pins installed.
12. Check the condition of the steering components by measuring the steering wheel play. If the cause of play is not due to loose connectors, it may be caused by wear in the steering column connections, tie rod ball joints, or steering gear. Check the outer tie rod ball joints.
13. To check the outer tie rod ball joints, lower the vehicle and watch them closely while an assistant rotates the steering wheel back and forth; any wear should be visible in the form of play between the tie rod end and the hub fastener. If a worn ball joint is found, it must be replaced. Nissan recommends that ball joints (with flat top surface) late types were replaced in pairs, even if only one was worn out.
Checking the suspension, wheels and tires
14. Park the vehicle on a level surface and shake it at each corner to check the suspension braces. If the rack is working properly, the body will return to its normal position and then stop. If the body oscillates more than once with little damping and signs of uncontrolled movement, the rack is considered faulty and should have. replaced.
15. Apply the handbrake and raise the front of the car.
16. Visually inspect all suspension components, looking for obvious signs of wear, damage or loose connections. Check the rubber dust caps on the ball joints of the lower suspension arm. Replace the ball joint if the cover is cracked, leaking holes or leaking lubricant. Check for oil leaks from the suspension struts.
17. Grasp the wheel at the 12 o'clock - 6 o'clock position and try to rock it. If there is play, first check the tightness of the wheel nuts, then the drive shaft nut. If they are properly clamped, repeat the test with an assistant pressing on the brake pedal. If there is no play now or it has decreased significantly, the hub bearings are probably worn out. If play remains, there is wear in the suspension components, especially likely in the lower control arm ball joints.
18. Spin the wheel quickly and listen. If the wheel spins smoothly and easily without noise and slows down and stops without jumping, the bearings are in good condition.
19. Using a large screwdriver or flat rod, check for wear at the suspension bushings and mounting points, moving them around to check for play. A small permissible play may be in the rubber bushings. If there is play, first check the tightness of the mounting nuts or bolts, using a torque wrench if possible. Any worn components must be replaced as described in the appropriate Chapters of this Section.
20. Lower the car and engage reverse gear (manual transmission) or "R" (automatic transmission). Block the front wheels. Raise the rear of the car. Release the handbrake and check the wheel bearings.
21. Check the condition and reliability of all rear suspension components, first visually then physically, as described above. Check crossmember, link and bushing installations, anti-roll bar installations and strut installations.
22. Check the rear wheel bearings as described above.
23. After checking, lower the vehicle and check the tire tread wear. If there is abnormal wear or the vehicle's steering and wheel alignment have deteriorated, check the wheel alignment.
