Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working.

2. Tire Inspection

Tools Required: Tire pressure gauge, visual inspection tools.
Check tire pressure and adjust as needed to manufacturer specifications.
Inspect tires for uneven wear patterns and replace if necessary.

3. Engine Mount Replacement

Tools Required: Socket set, torque wrench, pry bar.
Remove the bolts securing the engine mount to the engine and subframe using the socket set.
Lift the engine slightly using a jack to relieve tension on the mount.
Replace the old mount with a new one, ensuring proper alignment.
Torque the mounting bolts to the manufacturer’s specifications (typically around 40-50 Nm).

4. CV Joint and Driveshaft Inspection

Tools Required: Socket set, pry bar.
Inspect CV joints for any tears in the rubber boots or leaks.
If damaged, replace the CV joint or entire axle as necessary.
Check the driveshaft for any play or signs of wear. Replace if damaged.

5. Suspension Component Inspection

Tools Required: Jack and jack stands, socket set.
Raise the vehicle and inspect struts, shocks, and bushings for wear or damage.
Replace any worn or damaged components with OEM or quality aftermarket parts.
