A complete guide to 4WD servicing and maintenance

 Four-wheel drive, or 4WD, is made for off-road driving or driving in extreme conditions. They have become integral to rugged trucks and SUVs and can be activated with a lever, button or knob.

4WD is more sophisticated than All Wheel Drive (AWD). However, vehicle service and repair can be expensive. Therefore, it is wise to get it serviced regularly. Here is a guide to ensure that your 4WD system works with minimal maintenance and what points you must consider while servicing your vehicle.

• Frequent servicing:

It is difficult to spare money for servicing, especially when there are no visible problems in your 4WD system. However, remember that prevention is better than the cure. If you get your 4WD system serviced regularly, it will run smoothly for a long time, saving significant costs spent after repair. Also, it will enhance the longevity of your vehicle. 

- Check the owner’s manual. It mentions about ideal duration between two car services.

- If the service date is approaching, or has already been missed, book an appointment at the right service centre.  

• Determine the type of service:

Decide what you want to include in your 4WD mechanical service. It depends on the health of your 4WD system and your budget. It is best to opt for comprehensive servicing that covers all parts of the 4WD system.

Minor service will involve checking the major parts and the oil and filter change.

Major service is a comprehensive service per your vehicle model and current requirements.

• Keep an eye on fluid levels:

Maintaining fluid levels and replacing them regularly is essential to keep your 4WD system running without hindrance. Maintain a record of when was the last time you got the fluids like engine oil, radiator coolant, brake, clutch & power steering fluids checked or replaced. Also, ask the 4WD expert to suggest the next fluid check or replacement date. You can also enquire about which 4X4 accessories can enhance your driving experience.

• Health of tyres:

Maintaining correct pressure in the tyre is of utmost importance. Checking tyre pressure is a vital part of 4WD servicing. Correctly inflated tyres reduce fuel consumption and enhance the vehicle’s longevity. This ultimately saves money in the long run. The mechanic can also advise you to get wheel alignment and balance checked. Also, while using 4WD, you must rotate the tyres to prevent uneven wear.

• Wiper’s condition:

This part of the car is easily ignored. But it can cause severe trouble by bringing down visibility if they do not work well when required, leading to accidents. So, do get your wipers serviced and replaced regularly.

• Engine air filter:

Vehicles with 4WD are often used for off-road driving. Therefore, there is a high possibility of the engine air filter getting choked with dust. This can make way for dirty air to enter your engine and damage its efficiency. So, ensure you get the air filter checked and replaced if required during the 4WD service.

• Battery life:

Batteries are the heart of the 4WD system. So, if they are old and do not have enough fluids or show any signs of corrosion, replace them instantly. It might look like a considerable expense, but eventually, it will impede the damage to your car’s essential parts.

Also, remember to get the entire 4WD system deep cleaned while getting them serviced in Mulgrave or Sydney.
