Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Inspect Struts and Shocks
- Remove the wheel to gain access to the suspension.
- Check the struts and shocks for any signs of leakage or damage.
- If damaged, proceed to replace:
  1. Remove the strut assembly by unbolting it from the strut mount and lower control arm.
  2. Disconnect any sensors or brake lines attached to the strut assembly.
  3. Install the new strut/shock assembly in reverse order, ensuring proper torque specifications (refer to service manual for torque values).
Check and Replace Bushings
- Inspect control arm bushings for wear.
- If worn, use a bushing removal tool to press out the old bushings.
- Press in new bushings and install control arms back to their mounts, torqueing to specifications.

3. Inspect Exhaust System

Check for any loose hangers or damage to exhaust components.
Tighten or replace any loose or damaged parts as necessary.

4. Verify Wheel Bearings

Lift the vehicle and check for wheel play by shaking the wheel at 12 and 6 o'clock positions.
If play is detected, remove the wheel and replace the affected wheel bearing.

Tools Required:

Socket set
Torque wrench
Bushing removal tool
Jack and jack stands
Strut spring compressor (if replacing struts)

Parts Required:

Struts or shocks (if damaged)
Suspension bushings (if worn)
Wheel bearings (if needed)

Estimated Repair Time: 3-5 hours

Safety Warnings:

Always use jack stands when working under the vehicle.
Ensure the vehicle is securely supported before removing any components.
