Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather tools and parts: jack and jack stands, socket set, torque wrench, stethoscope, OBD-II scanner.

2. Inspect and Replace Damaged Components

Sub-step 1: If any loose or damaged suspension components (like control arms or struts) were found, replace them using the socket set.
- Tools Required: Socket set, torque wrench
Sub-step 2: If CV joints or axles are found to be damaged, remove the affected axle by:
- Removing the wheel and brake caliper.
- Unscrewing the axle nut and disconnecting the axle from the hub.
- Replacing with a new axle and reassembling in reverse order, ensuring to torque the axle nut to manufacturer specifications.

3. Replace or Repair Engine Mounts

Sub-step 1: If engine mounts are worn, support the engine with a jack and remove the mounting bolts.
Sub-step 2: Replace the old mounts with new ones and torque to the specified values.

4. Fluid Check and Replacement (if necessary)

Sub-step 1: Check and top off or replace the transmission fluid and differential fluid if low or dirty.
- Fluid Type: Use manufacturer-recommended fluids for both the transmission and differential.
