2. Inspect all suspension bolts and drivetrain connections for tightness.
3. Use a torque wrench to tighten any loose bolts to the manufacturer’s specifications.

3. Replace Worn Suspension Components

Tools Required: Socket set, spring compressor (if needed), pry bar
Parts Required: New struts, shocks, or control arms (if necessary)
Steps:
1. Remove the wheel to access the suspension components.
2. If replacing struts or shocks, use a spring compressor to safely remove the spring from the strut assembly.
3. Install new struts or shocks in reverse order of removal.
4. Reinstall the wheel and lower the vehicle.

4. Inspect Drivetrain Components
