Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Engine Mounts (if needed)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (typically found near the engine and transmission).
3. Visually inspect for cracks, breaks, or excessive wear.
4. Remove the bolts securing the engine mounts using a socket set.
5. Replace any damaged mounts with new, OEM parts.
6. Reinstall the bolts and torque them to the manufacturer’s specifications (usually around 40-50 ft-lbs, but verify).

3. Transmission Fluid Inspection and Replacement (if needed)

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and check the fluid level and color.
3. If fluid is low or burnt, drain the transmission pan using a socket set.
4. Replace the transmission filter if applicable.
5. Fill with new transmission fluid (use Toyota WS transmission fluid) until it reaches the proper level.

4. Check and Replace Drive Shafts (if needed)

Sub-steps:
1. Inspect the drive shafts and CV joints for any visible damage.
2. If damaged, remove the retaining clips and bolts securing the drive shaft.
3. Replace with new drive shaft components and secure them with the appropriate torque specifications.

5. Tire Inspection and Replacement (if needed)

Sub-steps:
1. Inspect all tires for uneven wear, bulges, or damage.
2. Rotate tires if uneven wear is detected, or replace tires if necessary.
3. Balance and align the wheels to ensure proper performance.
