Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Measure the tread depth using a tread depth gauge; replace tires if tread is below 3/32 inches.
2. Inspect for any punctures, bulges, or sidewall damage.
3. Replace tires with high-performance all-season or dedicated wet-weather tires if necessary.

Tools Required:

Tread depth gauge
Jack and jack stands

2. Traction Control System Check

Sub-steps:
1. Locate the wheel speed sensors on each wheel hub and check for dirt or damage.
2. Clean the sensors with a soft cloth and inspect the wiring for frays.
3. If any sensors are faulty, replace them with new OEM parts.

Tools Required:

Multimeter
Basic hand tools (sockets, wrenches)

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle and support it securely on jack stands.
2. Inspect the shocks and struts for leaks or physical damage.
3. Replace any worn or damaged components as needed, ensuring to torque bolts to manufacturer specifications.

Tools Required:

Torque wrench
Socket set
