Solution

1. Tire Inspection and Repair

Check for Damage: Look for any visible punctures, bulges, or uneven wear patterns on the tires.
Balance and Alignment: If imbalance or misalignment is detected, take the vehicle to a tire shop for balancing and alignment.

2. Engine Mount Replacement

Preparation:
- Gather tools: socket set, jack and jack stands, torque wrench.
- Disconnect the battery.
Remove Old Engine Mounts:
1. Raise the vehicle securely using a jack and place jack stands under the vehicle.
2. Locate the engine mounts (typically near the front and rear of the engine).
3. Remove bolts securing the engine mount to the engine and the subframe using a socket set.
Install New Engine Mounts:
1. Position the new engine mount in place.
2. Hand-tighten the bolts to hold the mount.
3. Torque the bolts to manufacturer specifications (usually between 45-55 ft-lbs, check specific vehicle manual).

3. Driveshaft and CV Joint Inspection/Replacement

Visual Inspection:
- Check for any visible damage to the driveshaft and CV joints.
Replace if Necessary:
1. Remove any securing clips or bolts from the CV joint.
2. Disconnect the driveshaft from the differential and wheel hub.
3. Install the new driveshaft and secure using the appropriate torque specifications.
