Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface and securely lift the rear using a jack and jack stands.
Disconnect the battery to ensure safety while working on electrical components if necessary.

2. Inspect Rear Suspension

Inspect the shock absorbers for leaks or damage.
- If damaged, remove the bolts securing the shocks using a socket set and replace with new units.
Check the rear control arms and bushings for wear.
- If bushings are worn, remove the control arms and press out the old bushings using a bushing tool. Install new bushings and reattach the control arms.

3. Inspect and Replace Rear Brakes (if necessary)

Remove the rear wheels using a lug wrench.
Inspect brake pads for thickness; if below specifications (usually less than 3mm), replace them.
- Remove the caliper bolts with a socket set, slide off the caliper, and replace the pads.
Check the rotors for wear; if warped or below minimum thickness, replace them as well.

4. Check Exhaust Components

Inspect all exhaust hangers and clamps for looseness or corrosion.
- Tighten or replace any loose components to eliminate noise.

5. Verify Rear Tires

Inspect the rear tires for proper alignment and inflation.
- Inflate tires to the manufacturer’s recommended PSI if necessary.
- If wear is uneven, consider rotating or replacing the tires and performing a wheel alignment.
