Benefits of 4WD service
Four-wheel drive is idyllic for driving in conditions such as low to little traction. If you frequently take your vehicle off-road or drive in snow, you would greatly benefit from the four-wheel drive. A few modern vehicles engage 4-wheel drive automatically. So, you need not do anything to turn it on. This automatic system generally turns on when the wheels tend to slip. Besides, it improves the fuel economy.
Things to Remember
- The four-wheel drive vehicles have a transfer case. It means the rear and front drive shafts will be locked together, if the four-wheel drive is engaged. It requires periodic service. You need to check the fluid level in it.
- There is a motor in the transfer case. It is exposed and has an electrical connector on it. You must open the connector at least once a year to coat it with di-electric grease. It is necessary to do so because it has a bad habit of corroding internally.
- You must keep looking at the brake lines of the vehicle. You need to prevent them from getting rust. One way to help prevent is to use anti-corrosion spray or white lithium grease on all of the brake lines. It is the vital part of 4WD service.
- Next thing to keep in mind is the rear differential. You have to change the fluid in it on a regular basis. Make sure that you use the appropriate lubricant, as most of these would be locking differentials. If you use the wrong lubricant, the locking mechanism might not work.

Oil
Oil is the lifeblood of every vehicle’s engine. Oil keeps your engine working properly and rotating its parts smoothly. Over time, small bits of metal and exhaust gases from cylinders contaminate the oil. In turn, it reduces its effectiveness. If the oil becomes too thin, it would not lubricate the engine. Many newer vehicles come with a complex monitoring system, which evaluates many aspects of the oil to determine how long it would last.
Air Filter
Do not forget to check your vehicle’s air filter at the time of 4WD service. If your air filter is clogged, it might reduce your gas mileage, horsepower, and cause your engine to run rough. The frequency of which you would require changing your air filter depends on two factors. The atmospheric conditions and how many miles you drive your vehicle each year.
Brake Pads
The brake pads are essential. How often you require changing your brake pads depends on:
- Your driving styles
- Weight of your vehicle
- Type of driving
- Condition of your brake rotors, and
- Quality of the brake pads
