Most in the San Diego area may not know much about transfer cases, but if you have a four-wheel drive vehicle, you've got one. It makes sure you have power available for both the front and rear axles when driving around CA.

For example, if you have a rear-wheel drive SUV, power goes to the rear wheels until you need four-wheel drive. That's when the transfer case steps in and transfers some of the power to the front wheels as well. You might use a shift lever to go into four-wheel drive, it could be a button on the dash or it might even go into four-wheel drive automatically, depending on your vehicle.

The transfer case is serviced at Bonita Point Auto Care, Inc. by periodically draining its fluid and replacing it with fresh fluid. We also check for leaks and damage. Transfer case fluid cools and lubricates the gears, chains, bearings, shafts and other parts for Chula Vista motorists. Over time, the additives in the fluid wear out and it doesn't protect as well. Also, bits of metal and clutch material wear off and contaminate the fluid. There isn't a filter in the transfer case, so if Chula Vista drivers allow the contamination to stay for too long, it'll further accelerate wear.

Now, your owner's manual may not have a recommended interval for when you should change your transfer case fluid – so ask your Chula Vista service advisor at Bonita Point Auto Care, Inc.. There are several things that affect how often you should change the fluid, so tell her how often you use four-wheel drive: if you drive in wet Chula Vista environments like places you cross streams or drive through mud and snow. That kind of stuff really shortens the drain interval.

Transfer case parts will eventually wear out and you'll have to make repairs. But properly servicing your transfer case at Bonita Point Auto Care, Inc. will keep that day as far in the future as possible.
