Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Tire and Wheel Inspection

Sub-step 1: Remove the wheel covers or hubcaps, if applicable.
Sub-step 2: Inspect each tire for uneven wear, bulges, or sidewall damage. Replace any damaged tires.
Sub-step 3: Check wheel balance and alignment. If necessary, take the vehicle to a tire shop for balancing and alignment.

3. Suspension Inspection

Sub-step 1: Raise the vehicle using a jack and secure it on jack stands.
Sub-step 2: Visually inspect the suspension components (control arms, bushings, shock absorbers) for signs of damage or excessive wear.
Sub-step 3: Replace any worn suspension parts.

4. Driveshaft and Mount Inspection

Sub-step 1: Inspect the driveshaft for any signs of damage or excessive play in the universal joints.
Sub-step 2: If any issues are found, replace the driveshaft or universal joints as necessary.
Sub-step 3: Check engine and transmission mounts for any signs of cracking or failure. Replace if necessary.
