- Ensure that all bushings are intact and showing no signs of excessive wear.

3. Replace Worn Components

Sub-steps:
- If any components are found to be damaged during the inspection (e.g., bushings, sway bar links), remove them using appropriate tools.
- Install new parts by aligning them properly and tightening to manufacturer specifications (refer to service manual for torque values).
- Replace rear shocks or struts if they are leaking or worn out.

4. Inspect Driveshaft and Differential

Sub-steps:
- Check the driveshaft for any play and ensure the U-joints are functioning properly.
- If necessary, replace any worn U-joints with new ones.
- Inspect the rear differential for proper fluid levels and signs of wear or damage. Change fluid if necessary.
