Solution

1. Preparation

Gather 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 electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, tire iron, jack and jack stands.
Check tire pressures and inflate to the recommended levels.
Inspect tires for uneven wear; replace if necessary.
If tires are damaged, remove them using the tire iron and replace with new tires, ensuring proper torque specifications when reattaching (typically 80-100 ft-lbs).

3. Steering and Suspension Inspection

Tools Required: Wrenches, socket set, torque wrench.
Inspect tie rods, ball joints, and control arms for wear. Replace any worn-out components.
To replace a tie rod:
- Use a wrench to loosen the tie rod nut and disconnect it from the steering knuckle.
- Remove the tie rod from the steering rack.
- Install the new tie rod, ensuring to tighten the nut to manufacturer specifications (usually around 50-60 ft-lbs).

4. Wheel Balancing and Alignment

Tools Required: Wheel balancer, alignment machine (if available).
Take the vehicle to a professional for wheel balancing and alignment.
Verify that all specifications are within the manufacturer's guidelines.

5. Shock Absorber or Strut Replacement

Tools Required: Socket set, spring compressor (for struts).
If shock absorbers or struts are found to be faulty:
- Remove the mounting bolts and disconnect the shock/strut assembly from the vehicle.
- If replacing struts, use a spring compressor to safely remove the coil spring before replacing the strut.
- Reinstall the new shock/strut, ensuring all bolts are torqued to specifications.
