Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Weather Stripping

Tools Required: Trim removal tool, utility knife, adhesive.
Remove the old weather stripping around doors and windows using the trim removal tool.
Clean the surface where the new weather stripping will adhere.
Cut the new weather stripping to size and apply adhesive as necessary.
Press firmly to ensure a proper seal and allow to set according to adhesive instructions.

3. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure and inflate to the recommended PSI.
Inspect for uneven wear; if tires are damaged or worn, replace them.
If stones or debris are lodged in the tread, remove them carefully.

4. Wheel Bearing Inspection and Replacement

Tools Required: Jack, jack stands, lug wrench, bearing puller, grease.
Lift the vehicle and secure it with jack stands.
Remove the wheel and inspect the wheel bearing for noise or play.
If faulty, use a bearing puller to remove the old bearing and install a new one, ensuring it is properly greased.

5. Inspect and Secure Engine Components

Tools Required: Socket set, torque wrench.
Open the hood and visually inspect hoses and components for looseness or damage.
Tighten any loose bolts and ensure connections are secure.
