Solution

1. Preparation

Gather tools and parts needed for inspection and potential replacement.
Park the vehicle on a flat, stable surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Adjustment

Check tire pressure with a tire pressure gauge; adjust to manufacturer specifications.
- Recommended pressure for the Corolla E140 is typically around 30-32 PSI.
Inspect tires for uneven wear patterns; replace tires if necessary.

3. Suspension Component Replacement

Inspect Shock Absorbers/Struts:
- Perform a bounce test by pushing down on the front/rear of the vehicle and observe if it rebounds excessively.
- If they are leaking or not compressing properly, replace them.
- Use a socket set to remove the bolts securing the struts and install new units according to manufacturer instructions.
Replace Worn Bushings:
- Inspect control arm and sway bar bushings for cracks or deterioration.
- Remove old bushings using a bushing removal tool, and install new ones, ensuring proper alignment.

4. Wheel Alignment

After replacing suspension components, perform a four-wheel alignment.
- Adjust camber, caster, and toe angles to manufacturer specifications using an alignment machine.
