Solution

1. Preparation

• Gather tools and parts needed for repair.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid (if needed)

• Tools Required: Transmission fluid pump, socket set, drain pan.
• Remove the transmission fluid pan using a socket set.
• Allow the old fluid to drain completely into the drain pan.
• Inspect the pan for metal shavings or debris.
• Replace the filter if necessary, ensuring proper alignment.
• Reinstall the pan, torqueing bolts to the manufacturer's specifications.
• Refill with the recommended transmission fluid type through the dipstick tube or fill port.

3. Inspect and Replace CV Joints/Axles (if damaged)

• Tools Required: Jack and jack stands, socket set, pry bar.
• Raise the vehicle using a jack and secure it with jack stands.
• Remove the wheel and inspect the CV axle for damage.
• If damaged, use the socket set to unbolt the CV joint from the transmission and the wheel hub.
• Replace the CV joint or entire axle if needed, ensuring proper alignment.
• Reinstall the wheel and lower the vehicle.

4. Address Engine Mounts (if loose or damaged)

• Tools Required: Socket set, torque wrench.
• Inspect engine mounts visually for cracks or separation.
• If damaged, remove the bolts securing the engine mount with the socket set.
• Replace with new engine mounts, ensuring they are torqued to specified values.
• Recheck alignment and positioning after installation.
