my Volvo XC90 makes a loud noise when turning, what's causing it?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to ensure safety during electrical inspections.

2. Inspect and Replace Power Steering Fluid

• Tools Required: Funnel, power steering fluid (specific to Volvo).
• Sub-steps:
  1. Locate the power steering reservoir.
  2. Remove the cap and check the fluid level. If low, top off with the recommended fluid type.
  3. If the fluid is dark or contaminated, drain the reservoir and refill with new fluid.

3. Examine and Replace Faulty CV Joints

• Tools Required: Socket set, jack stands, torque wrench.
• Sub-steps:
  1. Lift the front of the vehicle using a jack and secure it with jack stands.
  2. Remove the front wheels for better access to the CV joints.
  3. Inspect the CV boots for tears or leaks. If damaged, replace the CV joint.
  4. Reassemble the wheels and lower the vehicle.

4. Inspect and Repair Steering Components

• Tools Required: Wrench set, torque wrench.
• Sub-steps:
  1. Check the tie rod ends for play by grasping the rod and moving it side to side.
  2. If movement is detected, replace the tie rod ends.
  3. Inspect the steering rack for leaks or damage, and replace if necessary.
  4. Reassemble all components and ensure all bolts are torqued to manufacturer's specifications.
