4X4 SERVICES

Comprehensive 4x4 and All-Wheel Drive Vehicle Services

When it comes to maintaining your standard 4-wheel drive (4x4) and all-wheel drive (AWD) vehicles, the skilled technicians at Covenant Automotive Repair & Service possess years of experience and specialized knowledge.

AWD systems operate as full-time 4-wheel-drive setups, where all four wheels receive torque from the engine simultaneously. These intricate systems require unique attention, and we're here to cater to their distinct needs. Below are some of the services we offer:


Differentials
The differential plays a pivotal role in distributing engine power to the wheels. It enables each wheel to rotate at different speeds, especially crucial during turns. To guarantee that your vehicle's differentials operate flawlessly, regular inspections and servicing are essential.

Driveline
The driveline serves as the vital link between the engine and the wheel axles. It encompasses the powertrain components, excluding the engine and transmission. Any malfunction in the driveline can immobilize your car since it hinders the transfer of energy from the engine to the wheel axles. Therefore, it is imperative to have your car's driveline routinely inspected and serviced.

Hubs, Seals, Studs, & Nuts
Wheel hub motors, or wheel motors, are electric motors integrated into the wheel hub itself, directly driving the wheel. To ensure a safer and smoother ride, it is crucial to replace damaged or worn-out wheel hubs promptly.

Maintaining functioning seals is essential for effective oil and grease sealing, particularly under diverse temperature and environmental conditions. Worn or damaged seals permit contaminants to infiltrate the bearing unit or cause lubricant leakage, leading to premature bearing failure. To safeguard your bearings, it's crucial to replace worn seals with new ones.

Studs are threaded fasteners that secure your truck's wheels to the wheel hub, via the brake disk or drum. If these wheel studs become stripped or damaged, they can pose serious safety risks. For your safety, replace any compromised wheel studs with high-quality replacements promptly.

Wheel nuts or lug nuts are fasteners that secure your vehicle's wheels to the threaded wheel studs on the wheel hub. Worn-out or damaged nuts jeopardize the secure attachment of your wheels to the hub, posing a risk of wheel detachment. To ensure the safe and secure fastening of your truck's wheels, reach out to Covenant Automotive Repair & Service in Tucson, AZ today.

Transfer Cases
The transfer case plays a crucial role in the four-wheel drive systems of both 4x4 and AWD vehicles. It receives power from the transmission and transmits it to both the front and rear axles. This transfer of power can be achieved through a set of gears or, in most modern cases, chain-driven mechanisms. The transfer case is connected to the transmission and axles via driveshafts.

Transmissions
Transmission repair is a matter of paramount importance, as the transmission is closely linked to key vehicle components, impacting your overall safety. Our transmission services encompass tasks like filter replacement and fluid draining to prevent transmission damage. If you encounter transmission issues such as shifting problems, slipping, stalling, fluid leakage, or a lit service indicator, it is imperative to schedule an appointment.

Wheel Bearings
Wheel bearings reside within the wheel assemblies and enable the wheels to spin freely while being connected to the brake system. Over time, they can wear out, leading to a vibrating suspension and noisy operation while driving. In severe cases, if they fail entirely, your vehicle can become challenging to control and unsafe to drive. The replacement interval for wheel bearings varies, but periodic checks for leaks and wear are crucial.


4x4 FAQs

Is there a difference between four-wheel drive and all-wheel drive?

Both all-wheel drive (AWD) and four-wheel drive (4WD) engage all four wheels, but with a twist. AWD uses three differentials (front, rear, and center) for continuous power distribution, making it ideal for everyday driving with improved traction. 4WD typically uses two differentials and can be switched between two-wheel drive and four-wheel drive modes, offering more control for off-road adventures.

Are 4x4 vehicles meant just for off-road driving?

While off-roading is their specialty, 4x4s aren't just for outdoor enthusiasts. Their enhanced grip and stability tackle slippery city streets and uneven landscapes with ease, offering peace of mind for families, outdoor enthusiasts, and anyone who values dependable performance in diverse conditions.

Is running a four-wheel drive expensive?

Four-wheel drive fuel economy and maintenance might seem daunting, but it's a nuanced picture. Frequent off-road adventures and towing will impact costs differently than city commutes. Analyze your driving habits and needs before comparing 4x4 and 2 wheel drive costs.

    We found our former auto repair shop closed only to "randomly" pull into Mark Knaak's, Covenant Automotive, LLC today. While it makes sense to get an appointment, they performed mechanical service on two of our cars without hesitation. They were pleasant to work with, asked appropriate questions, provided information and excellent service second to none. Mark is a VERY experienced mechanic and able to work on almost ANY make or model. He specializes in "high end" luxury vehicles. Raise your prices, Mark! You deserve EVERY penny. THANK YOU. We'll be back!

    Mark was honest, kind, worked very efficiently, and made my experience at Covenant Automotive not only enjoyable but heaven sent. I will certainly be taking my Nissan to him and his team as long as they are in business in Tucson. Thank you Mark for your kind heart and excellent service!

    Very impressed! I just dropped in before 3pm on 2/19/2018 with my 2001 F150 Lariat, thinking I might need a fuel filter replacement..."Service Engine Soon" light was lit. When they checked, it was determined the truck was misfiring on #8. I thought I'd have to arrange another day to bring it in for the estimated 3 hour job; Mark assured me that he could get two guys to work on it right away, and if they had to go a little past 5, they'd do whatever was needed to get me going. Well, a whole set of plugs and a new coil, and they finished at 4:50! Amazing work!

    My stepdad brings in our cars to Mark and he does a fabulous job taking care of them! I took my Nissan Maxima in for an oil change and to get my splash guard nailed back into place. They took excellent care of my car and I am very impressed with them! Will be back with my husband's car for an oil change, and will keep coming back! The oil change is a great price for the service that you receive!

    Mark has worked on my Mercedes E350...and now a doge journey (only an oil change and inspection before cross country trip.) The service and above all, honesty you'll get here is just the best. We're moving east and will miss them!
