Four Wheel Drive System
Four-Wheel Drive System
Four-wheel drive systems allow all four wheels on a vehicle to spin simultaneously.
All 4WD vehicles have a transfer case between the front and rear axles that prevents the axles from spinning at different speeds.
The transfer case allows the engine to provide maximum torque to the axle and wheels to maintain traction.
Different 4WD configurations exist, and each variation employs other technologies to meet the driver’s needs.
Some 4WD systems have a locking differential.
This means both wheels on the axle will turn together to achieve maximum traction.
Another variation is the limited-slip differential.
It can detect a slide or slip in one wheel and send torque to the other wheel to regain traction.
A manual hub requires users to manually engage the front wheel drive mechanism to fully engage the 4WD system.
In contrast, an automatic hub allows users to automatically command the front wheels in order to engage the 4WD system.
Our service staff has extensive experience working on all types of 4WD systems.
Benefits of Four-Wheel Drive System
Smooth and consistent four-wheel drive system performance is made possible through routine maintenance, which can vary from vehicle to vehicle and from system to system.
This makes consulting your owner’s manual extremely important when it comes to scheduling services within the proper maintenance intervals.
Rougher terrain can have a heavier impact on the life of your 4WD system.
When scheduling 4WD maintenance, consider where you drive most often and how much time your vehicle spends traversing difficult terrain.
Symptoms that show 4WD system repairs are needed include excessive noise while switching between gears, transfer case gear leaks and failures, unusual vibrations, and of course, a warning light on the dashboard.
Whether you are in need of an inspection or repair, our staff is ready to help you with all aspects of 4WD maintenance.

Customer Testimonials
We stand by our work.
The owner John is very knowledgeable and the whole staff is friendly. I came for an oil change and to have my tires serviced (rotation, alignment and balance) because I thought they needed it. John told me I didn’t need service to my tires and they rode very well; no need to spend the money on a service that wasn’t needed. We all know many establishments would try to push a service for a dollar so his honesty is appreciated. Reasonable pricing and great service. Highly recommend! Services: Tire rotations, Oil change

Since 2003 I have entrusted all my vehicular repairs and maintenance to John and his team at C & D Auto Service. In that time I have referred my family and friends to this shop. You are in safe and steady hands with John.

Very knowledgeable HONEST people. Saved me over 2K based on a quote I would have received from another shop. Services: Tires, Steering & suspension repair, Brakes, Electrical
Ronnell FieldsGoogle ReviewI had slow leak from a nail puncture and I was told by another tire shop that run flat tires could not be fully patched. He said it would cost $75 for a temporary fix but he recommended replacing, so I bought another tire online. [...] Thomas did such great work that it was not a temp fix at all and basically let me know the other place did not know what they were talking about. I have had no issues with the tire and its been over 3 months. He also said the repair came with a lifetime warranty so this place is all good in my book. Highly recommend. Service: Tires
