Four Wheel Drive System
Description of Four Wheel Drive Systems
Four wheel drive systems allow all four wheels on a vehicle to receive engine power simultaneously, providing enhanced traction and control in challenging driving conditions.
All 4WD vehicles have a transfer case located between the transmission and the front and rear axles.
The transfer case distributes power between the front and rear wheels and allows the driver to switch between two-wheel drive and four-wheel drive modes.
Some 4WD vehicles use locking hubs that can be locked manually or electronically to engage the front wheels when four-wheel drive is needed.
Full-time 4WD systems supply power to all four wheels continuously, while part-time systems require the driver to manually engage four-wheel drive for off-road use.
The four-wheel drive system is essential for vehicles used in off-road conditions, mountains, snow, or muddy terrain.
Benefits of Four Wheel Drive System Service
Common four-wheel drive issues include transfer case fluid leaks, hub engagement problems, grinding noises, vibration when shifting between 2WD and 4WD, or failure to engage four-wheel drive mode.
Transfer case servicing involves fluid changes and filter replacements to maintain proper operation and prevent wear.
Hub service ensures that locking hubs engage properly when four-wheel drive is activated.
Regular inspection can identify wear in the transfer case, front and rear differentials, and driveshafts before they fail.
Proper maintenance of your 4WD system ensures reliable engagement of all four wheels, prevents damage to the transfer case and axles, improves traction and vehicle control in challenging conditions, and maximizes the lifespan of your 4WD components.
Whether you drive in snow, mud, or mountain terrain, a well-maintained four-wheel drive system keeps you moving safely.

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 Glenn Dale, Tire, Auto & Roadside Assist. In that time I have referred my family and friends to this shop. You are in safe and steady hands with John.

Ronnell FieldsGoogle Review
I 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
