my Volvo XC90 makes a popping noise when turning, what could it be?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Wear safety gloves and goggles.

2. Inspect and Replace CV Joints

1. Lift Front of Vehicle: Use a jack to raise the front of the vehicle and secure it on jack stands.
2. Remove Wheel: Use a socket set to remove the lug nuts and take off the front wheel.
3. Check CV Joint: Inspect the CV joint for any signs of damage or torn boots.
   • If damaged, proceed to replace the CV joint.
4. Remove CV Axle: Unbolt the CV axle from the transmission and the wheel hub.
5. Install New CV Axle: Insert the new CV axle and torque the bolts to manufacturer specifications (typically around 30-50 ft-lbs).

3. Inspect and Replace Suspension Components

1. Check Ball Joints: Inspect the upper and lower ball joints for wear.
   • If worn, unbolt and replace with new ball joints.
2. Inspect Control Arms: Look for cracks or damage on the control arms.
   • Replace if necessary by unbolting them from the chassis and suspension components.
3. Check Strut and Shock Absorbers: Inspect for leaks and excessive play.
   • Replace if necessary by unbolting from the top and bottom mount.

4. Verify Steering Components

1. Check Steering Rack: Inspect for any signs of leakage or wear.
   • If damaged, replace the steering rack.
2. Inspect Tie Rod Ends: Check for play in the tie rod ends.
   • Replace if there is noticeable movement.
