Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.

2. Inspect and Replace Suspension Components

Lift the Vehicle
- Use a jack to lift the front and rear of the vehicle; secure it with jack stands.
- Tools Required: Jack, jack stands, socket set.
Inspect Suspension Parts
- Examine struts, control arms, and bushings for wear, cracks, or breaks.
- If any components are damaged, proceed to replace them.
Remove and Replace Damaged Components
- For struts:
  1. Remove the wheel.
  2. Unbolt the strut from the control arm and the top mount.
  3. Replace with a new strut and reassemble.
- For control arms:
  1. Unbolt from the chassis and control arm.
  2. Replace with a new control arm and reattach.
- Torque values should be followed according to manufacturer specifications.

3. Inspect and Replace Drivetrain Components

Check CV Joints and Drive Shafts
- Inspect for torn boots or excessive play.
- If damaged, replace with new CV joints or entire axle assemblies.
Remove and Install New CV Joint/Axle
- Remove the wheel and hub assembly if necessary.
- Unbolt the CV joint from the transmission and control arm.
- Install the new CV joint/axle and reassemble.

4. Check Engine Mounts

Inspect Engine Mounts
- Look for cracks or degradation in rubber mounts.
Replace Engine Mounts if Necessary
- Raise the engine slightly using a jack.
- Remove the bolts securing the mount and replace with new mounts.
- Torque to manufacturer specifications.
