Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool if it has been recently driven.

2. Tire Inspection

Tools Required: Tire pressure gauge, tread depth gauge
Check and adjust tire pressure to the manufacturer’s specifications.
Inspect tire tread depth and for any signs of uneven wear.
Replace tires if necessary.

3. Suspension Component Inspection

Tools Required: Socket set, torque wrench
Remove the front wheel to gain access to the suspension components.
Inspect the shocks and struts for leaks or physical damage.
Check the control arms, bushings, and springs for any signs of wear or damage.

4. Shock Absorber Replacement (if needed)

Tools Required: Wrench set, strut spring compressor, floor jack
Lift the vehicle safely using a jack and secure it with jack stands.
Remove the old shock absorber or strut assembly using a socket set.
If replacing struts, compress the coil spring and remove it from the strut assembly.
Install the new shock absorber or strut and reassemble in reverse order, ensuring to torque bolts to manufacturer specifications.

5. Wheel Alignment

Tools Required: Wheel alignment machine
After replacing any suspension components, perform a wheel alignment to ensure proper handling.
Adjust camber, caster, and toe as per manufacturer specifications.
