4X4 SERVICES

The technicians at D & B Bear Service have years of experience working on standard 4-wheel drive (4x4) vehicles as well as all-wheel drive (AWD) vehicles. AWD is a full-time 4-wheel-drive system (all four wheels receive torque from the engine simultaneously) that employs a center differential that allows each tire to rotate at different speeds.

We understand the special needs of these vehicles. These are some of the services we offer.


Transmissions
Transmission repair is not something to take lightly. The transmission is connected to key parts of your vehicle and needs to be working properly for your safety. Transmission services include replacing filters and draining fluids to prevent transmission damage. Typical transmission issues that may lead to repair may include shifting issues, slipping, stalling, fluid leaking, and the service light turning on. If you are concerned that you may need transmission repair, don't hesitate to schedule an appointment at D & B Bear Service today.

Transfer Cases
A transfer case is a part of a four wheel drive system found in four wheel drive and all wheel drive vehicles. The transfer case receives power from the transmission and sends it to both the front and rear axles. This can be done with a set of gears, but the majority of transfer cases manufactured today are chain driven. The transfer case is connected to the transmission and also to the front and rear axles by means of drive shafts. Trust the automotive experts at D & B Bear Service for all your transmission repairs.

Differentials
The differential transfers the engine power to the wheels. One important function of the differential is to pass on power to the wheels while allowing them to rotate at different speeds - thus the name differential. When turning, the outer wheels travel a larger distance than the inner wheels do (also the front wheels travel a longer distance than the rear wheels). This means that all four wheels travel at different speeds during a turn and this is where the differential comes in to help. To make sure your vehicle's differentials are working properly, have them checked regularly. Contact D & B Bear Service today for differentials examination and servicing.

Driveline
A driveline is a part of your motor vehicle that connects the engine and the transmission to the wheel axles. The driveline consists of the parts of the powertrain less the engine and transmission. Failure of the driveline means that the car would not move since energy cannot be transmitted from the engine to the wheel axles. Therefore, make sure that your car's driveline is regularly inspected and serviced. And, at D & B Bear Service, you can have the driveline serviced by experts.

Alignment
Wheel alignment (or simply alignment) is standard car maintenance that involves adjusting the angles of the wheels so that they are set to the manufacturer's specifications. The main purpose is to let the suspension and the steering systems operate at their desired angles - this reduces tire wear. Alignment is a complicated process and not all mechanics get it right. To have experts handle your car's alignment, visit D & B Bear Service.

Wheel Bearings
Wheel bearings are found inside of wheels, allowing the wheels to spin freely, and are connected to the brake system. They can become worn over time, causing a vibrating suspension and noisy rubbing as the car is driven. If they break completely, the vehicle will become very difficult to control and unsafe to drive. Replacement interval for wheel bearings varies greatly, but they should be checked for leaks and wear periodically. D & B Bear Service can make sure that your bearings are in good shape and let you know if they need replacement.

Hubs, Seals, Studs, & Nuts
A wheel hub motor, also referred to as a wheel motor, is an electric motor incorporated into the wheel hub and drives it directly. You can have a safer and smoother ride today by replacing your warped and worn out wheel hubs. Let D & B Bear Service replace your worn out hubs today.

Properly working seals provide oil and grease sealing - offering enhanced performance in a wide range of temperatures and environments. Worn out or warped seals allow external contaminants to enter the bearing unit or let lubricant escape from the unit. This ultimately leads to premature failure of the bearing unit. To keep out contamination and retain lubricant in the bearings, have the seals replaced with new ones. To have the seals replaced by experts, contact or visit D & B Bear Service today.

Studs are the threaded fasteners that hold on the wheels of your truck. The wheel studs are permanently mounted on the wheel hub through the brake disk or brake drum. To secure the wheel, nuts (lug nuts) are fastened over the stud. Stripped wheel studs can be quite dangerous. Damaged wheel studs should be replaced with new ones immediately. To have your truck's wheel studs replaced with high quality ones, call 541-752-3316 or visit D & B Bear Service today.

A wheel nut or lug nut is a fastener for securing a wheel on the hub. A set of lug nuts are used to secure a wheel to the threaded wheel studs (which are fixed to a wheel hub). Worn out nuts means one thing - the wheel is not fixed securely on the vehicle which puts the vehicle at the risk of rolling over. To have your truck's wheels securely fastened to the hub, contact or visit D & B Bear Service in Corvallis, OR 97330 today.


What Our Customers Are Saying

I worked for and was service manager at D & B BEAR for 31 years and have recently changed careers. Owner Denny Rice is a one-of-a-kind suspension specialist & provides a great family-driven full-service shop that you can count on. Thank you for the time spent with you all.


-Steven Graves

My parents have owned D & B Bear service for nearly 40 years. They pride themselves on being honest and always putting the customer first. They also have always offered friendly service. My father started working at his family's business when he was 12 years. His experience is something that you don't find that often. If you are looking for great, friendly, honest service, give Jack a call today.


-Jeanette Doane

We discovered these guys from a person who sold us a used car. It was a '94 Honda they had been responsible for since it was new. I have been driving for 55 years and have used many repair shops in many cities. We have used these guys on many occasions in the last several years for all of our cars' repairs. I used to work on cars myself when I was young so I know when I am getting BS. These guys are very very good - the best I have ever had. Do yourself a favor and give them a shot.


-James Denning

Great, friendly service. They kept me informed about the progress and estimates for the repairs they did throughout the day. I will always take my car back here as long as I live in Corvallis.


-Anthony Zak

They have done me right a couple times now by coming in with quotes under others, and never going over their own quote, and my truck has been great!


-Robert Voss

Very knowledgeable and friendly. We were recommended to them by our neighbors and rightly so! They did a great job fixing our car and did it so fast it surprised us and all of my coworkers. Thanks for getting us back on the road so quickly.


-Steve Z

Super friendly people, extremely helpful. Took a look at my brakes and explained the problem piece by piece to me, so I could make an informed decision. Wonderful folks, I'd recommend them to anyone, and I will definitely be returning for any future car issues.


-Steven Alexander Czyz

Great friendly service and reasonable.


-Larry Hood

They helped me so quickly and treated me so nicely! Fair price and some really nice people.


-Kelly Conklin

Les Schwab wanted me to do some major repairs. I took my car to D & B, and they said my car didn't need it. The dealer is more expensive, and they want to do additional maintenance than D & B recommends. These guys are honest, and they are not just in it for your money.


-Jared Martinsen

We had some problems with our radiator on our way home for Thanksgiving and ended up at D & B. They told us we needed a new radiator, but it was late in the day, and no one in town had one. We didn't end up having the work done here because of travel logistics, but they were very helpful and kind enough to let us hang out in their office with a dog and baby while we figured out our tow truck. Very nice folks.
