Flush the system with fresh power steering fluid until the fluid runs clear.
Reconnect the return line and refill the reservoir to the proper level.

4. Check and Adjust Steering Components

Inspect the steering rack and pinion for leaks or damage.
Tighten any loose bolts or fasteners in the steering assembly.
If necessary, replace any worn or damaged bushings or linkages.
