Solution

1. Preparation

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

2. Inspect and Secure Components

Tools Required: Socket set, torque wrench, pry bar
Check all visible bolts and fasteners in the drivetrain and suspension assemblies. Tighten any loose bolts to factory specifications.
Use a pry bar to check for excessive play in CV joints and differential components. Replace any worn joints or components as necessary.

3. Fluid Replacement

Tools Required: Fluid pump, drain pan, funnel
Drain the transmission and differential fluids using a drain pan. Replace with manufacturer-recommended fluids.
Refill the transmission and differential using a fluid pump, ensuring the correct amount is added as per specifications.

4. Component Replacement (if necessary)

Parts Required: New CV joints, transmission mounts, or differential mounts (if any are found to be damaged)
Remove and replace any worn or damaged components. For example, if CV joints are faulty, remove the axle assembly, replace the joints, and reinstall.
Ensure all fasteners are torqued to the manufacturer’s specifications.
