•Uneven tire wear observed on front tires
•Vehicle pulls to one side while driving
•Brake pedal pulsation when braking

Diagnostic Steps

1
Inspect tire condition and pressure to ensure they are within manufacturer specifications.
2
Check for wheel balance by using a wheel balancer.
3
Examine suspension components (e.g., control arms, tie rods) for wear or damage.
4
Inspect brake components (e.g., rotors, pads) for warping or uneven wear.
5
Perform a wheel alignment check to assess proper alignment settings.
6
Test drive the vehicle to replicate the shaking and pinpoint the speed range.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Safety warning: Always wear safety glasses and gloves when working on vehicles.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, tire iron, jack, jack stands.
Check tire pressure using the tire pressure gauge; inflate to recommended PSI if necessary.
Inspect tires for uneven wear patterns, bulges, or damages. Replace if necessary.
If tires are worn, remove them using the tire iron and replace with new tires, ensuring proper torque (typically 85-100 ft-lbs for Porsche).

3. Wheel Balancing

Tools Required: Wheel balancer.
Mount the tires on a wheel balancer.
Spin the tires to check for balance; add wheel weights as needed to achieve proper balance.

4. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, pry bar.
Visually inspect control arms, tie rods, and ball joints for signs of wear or play.
Replace any worn or damaged components with OEM parts.
Torque suspension components to manufacturer specifications (refer to repair manual for exact values).

5. Brake Inspection

Tools Required: Brake caliper tool, torque wrench.
Remove the wheel to access the brake components.
Inspect brake rotors for warping; use a micrometer to measure thickness.
Replace warped rotors and worn brake pads.
Reinstall wheels and torque to manufacturer specifications.

6. Wheel Alignment

Tools Required: Alignment machine (performed at a shop).
After all repairs, have a professional perform a 4-wheel alignment to ensure proper alignment settings.
