Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Lift the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Suspension Components

Control Arms/Bushings
- Remove the wheel to access the suspension components.
- Inspect control arms for cracks or excessive wear in bushings.
- If damaged, remove the control arm bolts using a socket set and replace with new control arms.
- Torque the bolts to manufacturer specifications (typically around 80-100 Nm).
Shocks/Struts
- Remove the wheel.
- Unbolt the shocks/struts from the top mount and lower mount using appropriate sockets.
- Replace with new shocks/struts and ensure they are aligned correctly.
- Torque all mount bolts to manufacturer specifications.

3. Inspect and Replace Drivetrain Components

Tie Rod Ends and Ball Joints
- Check for play by applying pressure to the tie rod ends and ball joints using a pry bar.
- If excessive movement is detected, use a socket set to remove the tie rod end or ball joint.
- Replace with new components and torque to specifications.
Driveshaft and CV Joints
- Inspect for any visible damage or excessive play.
- If necessary, unbolt the driveshaft and replace the CV joints or entire driveshaft as needed.
- Ensure proper alignment and torque bolts to specifications.

4. Check Engine and Transmission Mounts

Inspect mounts visually for cracks or excessive movement.
If damaged, unbolt the mounts and replace with new ones, ensuring proper alignment.
Torque bolts to specifications.
