Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Worn Components

Inspect Suspension Bushings:
- Remove the rear wheel to gain access to the suspension components.
- Check all bushings for cracks or excessive wear.
- If damaged, proceed to replace the bushings.
Replace Shock Absorbers (if necessary):
- Remove the bolts securing the shock absorbers at both ends.
- Carefully remove the old shock absorbers from their mounts.
- Install new shock absorbers, ensuring they are oriented correctly.
- Torque the mounting bolts to the manufacturer’s specifications (typically around 50 ft-lbs).

3. Check and Adjust Driveshaft

Examine Driveshaft for Play:
- Inspect the driveshaft for any signs of damage or excessive play.
- If the driveshaft is worn, remove it by unbolting the flanges at both ends.
- Replace with a new driveshaft if necessary and torque bolts to manufacturer specifications.

4. Differential Fluid Check

Check and Replace Differential Fluid:
- Remove the fill plug on the rear differential.
- Check the fluid level; it should be at the bottom of the fill hole.
- If low or contaminated, drain the old fluid and refill with proper differential fluid (typically 75W-90 gear oil).
- Replace the fill plug and torque to specifications.
