Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the engine mount to the engine block and subframe using a socket set.
Use a pry bar to slightly lift the engine for easier access.
Remove the old engine mount and replace it with a new mount, ensuring it is properly aligned.
Torque the mounting bolts to the manufacturer’s specifications (typically around 30-40 Nm).

3. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, clean containers
Locate the transmission fluid dipstick or fill plug.
Remove the fill plug and use a fluid pump to extract old fluid.
Inspect the color and smell of the fluid; if it’s dark or burnt, it needs changing.
Refill the transmission with the correct type of fluid (consult the owner’s manual for specifications).
Ensure the transmission is at the right level by checking the dipstick.

4. Inspect Drive Shafts and CV Joints

Tools Required: Jack stands, socket set
Raise the vehicle and secure it on jack stands.
Visually inspect the CV joints for tears in the rubber boots or excessive play.
If any damage is found, remove the drive shaft and replace the faulty CV joint or the complete assembly.
