How To Do a 4WD Vehicle Inspection

If you are planning to hit the road using your 4WD vehicle anytime soon, it is imperative that you do a vehicle inspection to ensure you and your passengers' safety. There are two basic types of inspection that you can do: pre-trip inspection and post-trip inspection.

Pre-trip inspection. This type of inspection should be performed minutes before you hit the road. The purpose of this type of inspection is to ensure that all systems are equipments are functioning properly to ensure that you will not encounter mechanical problems while on the road. 

Here are some things you need to do when conducting a pre-trip inspection of your 4WD vehicle:

  • Check if windshield wipers, lights, flashers, warning lights, horn, and CB radio are working properly
  • Test  whether emergency brakes and brake pedal are properly functioning
  • Double check the contents of your first aid kit and road toobox
  • Make sure that the fire extinguisher is within easy access
  • Check if there are adequate seatbelts if they are in proper condition
  • Inspect whether the light lenses, glass and mirrors are clean for
  • Test whether the steering is aligned
  • Check tires for correct inflation, signs of excessive wear and tear, cuts or breaks

Post-trip inspection. This type of inspection must be done when the trip has ended, preferably within 24 hours. If you are travelling for several days at a time, make sure that you conduct this type of inspection at the end of each day, preferably before you rest for the night. This is to ensure that your 4WD vehicle can withstand another day of rigorous traveling in rough terrain.

At the end of each day of your trip, inspect your vehicle for structural integrity, security, wear and tear type items. Here are some things you should look for:

  • Leaks in the  brake, cooling system, engine, and other possible fluid leaks
