Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts while working.

2. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel using a socket set.
3. Inspect the CV joint boots for any tears or leaks. If damaged, proceed to replace.
4. Remove the axle nut using a torque wrench and socket.
5. Disconnect the lower control arm from the steering knuckle to free the axle.
6. Pull the CV axle out of the transmission and replace it with a new unit.
7. Reassemble in reverse order, ensuring all bolts are torqued to manufacturer specifications (typically around 30-50 ft-lbs for the axle nut).

3. Inspect and Replace Steering Components

Sub-steps:
1. Examine the steering rack and pinion for any signs of wear or damage.
2. If worn, remove the steering rack by disconnecting the tie rods and any brackets securing it.
3. Install the new steering rack, ensuring proper alignment and tight connections.
4. Reconnect the tie rods and torque them to the specified values.

4. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Check the fluid level and condition; if low or contaminated, drain and replace with OEM fluid.
3. Bleed the system by turning the steering wheel from lock to lock several times.
