why does my Alfa Romeo Giulia 952 (2016-Present) feel unstable when turning?

Symptoms

• Steering wheel feels loose or unresponsive during turns
• Vehicle exhibits excessive body roll when cornering
• Uneven tire wear or visible tire damage
• Vibration or shaking through the steering wheel while turning
• Warning lights illuminated on the dashboard (e.g., traction control light)

Diagnostic Steps

1. Inspect tire pressure and tread depth on all four tires.
2. Check for any visible damage to tires, including bulges or cuts.
3. Examine suspension components for wear, including control arms, bushings, and shock absorbers.
4. Assess steering system for play, including the steering rack and joints.
5. Perform a wheel alignment check to ensure proper alignment settings.
6. Scan for any diagnostic trouble codes (DTCs) that may indicate electronic stability control issues.

Solution

1. Preparation

• Gather necessary tools and ensure a clean work area.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

• Sub-steps:
  1. Remove the wheel covers or hubcaps if equipped.
  2. Loosen lug nuts slightly but do not remove them.
  3. Lift the vehicle using a jack and secure it on jack stands.
  4. Remove the wheel and inspect the tire for damage.
  5. If tire wear is uneven or damage is found, replace the tire with a new one of the same specifications (ensure proper load rating and speed rating).

3. Suspension Component Replacement

• Sub-steps:
  1. Inspect all suspension components for signs of wear or damage.
  2. If any components (e.g., control arms, struts) are worn, remove them using a socket set and replace with OEM or high-quality aftermarket parts.
  3. Torque new components to manufacturer specifications using a torque wrench.

4. Steering System Adjustment

• Sub-steps:
  1. Check for play in the steering rack and tie rods.
  2. If damaged, replace the steering rack or corresponding tie rods.
  3. Reconnect and adjust any steering components as necessary.

5. Wheel Alignment

• Sub-steps:
  1. After replacing any components, take the vehicle to a professional alignment shop.
  2. Ensure that the alignment settings meet the manufacturer specifications.
