- Use a tie rod puller to separate the tie rod ends from the knuckle.
d. Disconnect Steering Rack Hoses:
- Locate the high-pressure and low-pressure hoses connected to the steering rack.
- Use the appropriate wrench to loosen and disconnect both hoses, allowing any remaining fluid to drain.
e. Remove Mounting Bolts:
