Just because a vehicle boasts more than 2-wheel drive capability doesn't necessarily mean that it's off-road capable.
What it does mean is better traction and power. When your car is distributing power to all four wheels, you're far less likely to find yourself stuck in snow, ice, mud, etc.
In most cases, however, this doesn't necessarily translate to better safety. Four-wheel drive doesn't mean any extra clearance for a vehicle (it sits just as far off of the ground as a two-wheel drive vehicle), any extra braking (all vehicles have brakes on each wheel, whether 2- or 4-wheel drive), or improved steering or handling.
Maintenance for a four-wheel drive vehicle is different from a two-wheel drive one, mostly because there are more parts involved. For example, a typical four-wheel drive car, such as a Jeep in Colorado Springs has the following:
- Transfer case (which needs periodic fluid changes)
- 2 Differentials or gear boxes (which require periodic fluid changes)
- Transmission (which needs fluid changes)
- 2 sets of hubs and bearings (that need to be cleaned and re-packed with grease)
- Drive shafts (that needs lubrication): one for the front wheels, one for the rear
A typical 2-wheel drive vehicle only has one differential, one axle of hubs and bearings needing grease, and one drive shaft.
Be careful, however! Most discount stores don't have ASE Certified technicians who understand how to properly inspect and maintain these extra moving parts and their lubrication needs, like in a Colorado Springs Jeep. Find the most reputable shop in your area to ensure that your vehicle will be serviced correctly, the first time you bring it in.
