Today we’re going to talk about transfer case service. Not a super sexy topic, but very important nonetheless. 🙂 Now, you 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 and the right time and in the right proportion. For example, if you have a rear-wheel drive SUV, power goes to the rear wheels until you need four-wheel drive.
