Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery cable to prevent any electrical issues.

2. Remove the Front Wheels

Use a jack to lift the front of the vehicle and secure it on jack stands.
Remove the lug nuts using a socket set and take off the front wheels.

3. Disconnect the Steering Rack

Remove the tie rod ends from the steering knuckles using a pickle fork or ball joint separator.
Unbolt the steering rack from the subframe. Typically, this requires removing several bolts with a socket set.
Disconnect the power steering lines from the rack, using a line wrench to avoid damage.
Carefully remove the steering column coupling from the rack (may require a Torx or Allen wrench).

4. Install the New Steering Rack

Position the new steering rack in place and reconnect the steering column coupling.
Reattach the power steering lines to the new rack, ensuring all connections are tight and leak-free.
Bolt the steering rack back to the subframe using the original bolts. Torque the bolts to manufacturer specifications (usually around 30-40 Nm, check specific values for your model).
Reconnect the tie rod ends to the steering knuckles.

5. Reassemble and Test

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Tighten the lug nuts to the manufacturer's specification (typically 100-120 Nm).
Reconnect the negative battery cable.
Fill the power steering reservoir with the appropriate fluid (refer to the owner's manual for specifications).
Start the engine and turn the steering wheel from lock to lock to purge air from the system.
