Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check the tire pressure and inflate to the manufacturer’s specifications.
Inspect tires for uneven wear or damage; replace if necessary.
- Use a lug wrench to remove tires and inspect tread depth and sidewall condition.
- If replacement is needed, mount and balance new tires.

3. Suspension Component Replacement

Tools Required: Socket set, torque wrench, pry bar, impact wrench
Inspect and replace any worn or damaged suspension components such as bushings, control arms, or struts.
- Remove the wheel and use a socket set to unbolt the affected components.
- Replace with OEM or high-quality aftermarket parts and torque to manufacturer specifications.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, torque wrench
Inspect the driveshaft and CV joints for damage.
- If damaged, remove the driveshaft by unbolting it from the transmission and rear differential.
- Replace the driveshaft or CV joints as necessary, ensuring proper alignment and torque to specifications.

5. Engine Mount Replacement

Tools Required: Jack stands, socket set, pry bar
