Solution

1. Fluid Inspection

Check Fluid Level: Remove the power steering reservoir cap and check the fluid level.
Condition Assessment: Look at the fluid color; it should be clear or slightly tinted. If it’s dark or has debris, it needs to be replaced.

2. Fluid Replacement

Drain Old Fluid: Place a drain pan under the steering fluid reservoir. Disconnect the return hose and allow the old fluid to drain.
Refill with New Fluid: Use manufacturer-recommended power steering fluid. Reconnect the hose and fill the reservoir to the recommended level.

3. Leak Repair

Locate Leaks: Inspect hoses and connections for any signs of fluid leakage.
Replace Damaged Components: If leaks are found, replace the damaged hoses or seals using appropriate tools.

4. Steering Linkage Inspection

Visual Inspection: Check tie rods and ball joints for any signs of wear or damage.
Replace Worn Parts: If any components are worn, replace them with OEM or high-quality aftermarket parts.

5. Steering Rack Maintenance

Inspect the Rack: Check the steering rack for corrosion or leaks.
Replace if Necessary: If the rack is damaged, it may require full replacement, which involves disconnecting it from the vehicle and installing a new unit.
