1. Low Power Steering Fluid:
Check the power steering fluid level in the reservoir. If it's low, add the recommended fluid and monitor the issue.
2. Leaking Power Steering Hoses:
Examine the power steering hoses and connections for leaks. If you find any, replace the faulty hose.
3. Faulty Power Steering Pump:
If the fluid is full and there are no leaks, the power steering pump might be failing, leading to reduced or no power assistance.
4. Steering Rack Issues:
The steering rack and pinion might be worn out or damaged, causing difficulty in steering.
5. Worn Steering Components:
Inspect tie rods, ball joints, and other steering components for wear or damage. Replace any worn parts as necessary.
6. Misalignment:
Wheel alignment issues can affect steering effort. Improper alignment can cause the steering to feel heavy or unresponsive.
7. Worn Tires:
Worn tires can increase rolling resistance and impact steering response. Proper tire inflation is also important.
8. Bearing Issues:
Faulty wheel bearings can cause the steering to feel stiff and increase the turning effort.
9. Transmission Issues:
Sometimes transmission problems, like a faulty transmission mount, can affect steering. Check the transmission mount for any signs of damage.
10. Electronic Issues:
If your Altima has electronic power steering, there could be an issue with the power steering control module or electrical connections.
If the issue persists or if you're uncomfortable resolving it yourself, it's best to have a qualified mechanic diagnose and rectify the problem to ensure safe driving conditions.
