Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and securely raised with jack stands.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Worn Components

Inspect Suspension Components:
- Check the upper and lower control arms, sway bar links, and strut mounts.
- Look for any signs of dry or cracked bushings.
Replace Worn Bushings:
- Use a socket set to remove the bolts securing the control arms.
- Use a bushing removal tool to extract old bushings.
- Lubricate and install new bushings in the same orientation as the originals.

3. Tighten Loose Hardware

Inspect and Tighten All Fasteners:
- Check all suspension bolts and fasteners for proper torque specifications.
- Use a torque wrench to tighten bolts to manufacturer specifications, which can usually be found in the service manual.

4. Lubricate Moving Parts

Apply Lubrication:
- Use a silicone-based lubricant on rubber bushings and joints to reduce friction.
- Ensure that any grease fittings on the suspension components are filled with appropriate grease.
