If leaks are found, replace damaged hoses or seals.
Clean the area around the steering rack and hoses to check for new leaks after repairs.

Raise the vehicle with a jack and secure it with jack stands.
Check the steering rack and pinion for signs of wear or damage.
Inspect tie rods and ball joints for play; replace if necessary.

5. Wheel Alignment

Use an alignment tool to check the alignment of the front wheels.
If misaligned, adjust the alignment according to manufacturer specifications.
