Unbolt the pump from its mounting bracket and remove it.
Install the new pump by reversing the removal steps, ensuring all bolts are torqued to factory specifications.
Reconnect the power steering lines and check for leaks.

4. Inspect and Repair Steering Linkage and Suspension Components

Raise the vehicle and secure it with jack stands.
Inspect the tie rods, control arms, and ball joints for wear or play.
Replace any worn components using a socket set and torque to manufacturer specifications.
Reassemble any removed components and lower the vehicle.
