Undercar Services: Maintenance & Repair

Rely on Northwest Automotive LLC in Defiance, OH 43512 to provide quality care for your vehicle's undercarriage. Stop by our shop to see how we can help you or call 419-782-7827 for more information.

To keep your vehicle running at peak performance, we provide undercar services that include:

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 Northwest Automotive LLC.

Anti-Lock Brakes
Anti-lock brakes prevent wheel lock-up when rapidly decelerating by automatically modulating the brake pressure during an emergency stop. With this system, the wheels are able to maintain traction with the road while braking. Failure of the anti-lock brakes could lead to an increase in the risks of multiple vehicle crashes and run-off road crashes. To avoid this, have your anti-lock brake system checked and repaired by experts. At Northwest Automotive LLC, we have anti-lock brake experts who will examine and repair your faulty ABS - keeping you safe.

Brake System Flush
Brake fluid is hygroscopic (it absorbs moisture). The absorbed moisture lowers the fluid's boiling point. It also corrodes the lines and cylinders. With the lowered boiling point, the brake fluid could boil during braking which makes you lose braking ability. Although this is an extreme scenario, it does happen in heavy braking. To reduce the effects of the absorbed moisture, auto manufacturers recommend that you have a brake flush done periodically. A brake system flush involves the replacement of used and contaminated fluid with fresh fluid. With Northwest Automotive LLC's quick lube services, you will have a brake system flush performed by brake experts. Call 419-782-7827 or visit Northwest Automotive LLC today.

Brakes
A brake is a mechanical device for slowing or stopping a vehicle (usually by means of friction). In short, a brake inhibits your car's motion. It lets you stop the car whenever and wherever you choose. Brakes are one of the most important parts of a motor vehicle. Without them, you would not be able to stop the car. If your vehicle's brakes are having issues, consider having them worked on. Brake experts at Northwest Automotive LLC can work on your car's brakes to ensure you have a safe drive.

Chassis
A chassis is the car's internal framework that supports the body and other parts like the wheels, engine, transmission, driveshaft, differential, and suspension. A weak or damaged chassis will translate to a weak car. To have a strong and properly working vehicle, have your car's chassis checked for defects. At Northwest Automotive LLC, there are experienced undercar service providers who can work on your chassis.

Custom Exhaust
A motor vehicle exhaust system is piping used to guide exhaust gasses away from the engine to the outdoors. Although the exhaust system's main purpose is to guide exhaust gases from the engine to the outdoors, it can be modified to increase engine power, reduce pollution, and reduce noise. To achieve this, you need to invest in a custom-made exhaust system.

At Northwest Automotive LLC in Defiance, OH 43512, we can create a custom-made stainless steel exhaust for your vehicle. We specialize in custom performance exhaust systems, stainless steel mufflers, mufflers, exhaust kits, racing mufflers, and exhaust accessories for a huge and diverse range of vehicles: customized cars, standard road cars, classic cars, kit cars, 4x4's, imports, and racecars.

Differential Flush
The differential is a car part that compensates for the difference in travel distance between the inner wheels and outer wheels when the vehicle is turning. Due to the differential's position in most non-four-wheel-drive (FWD) vehicles (located at the rear and under the car), it does not get any of the star treatment the engine gets. The one thing that every car owner needs to know is that failure of the differential will mean failure of the car. To save the differential from failure, you need to have differential fluid changed every 30,000 to 50,000 miles. Changing the oil on the differential is as important as changing the car's engine oil. Although checking and changing differential oil is pretty easy, you need to visit an auto shop to get a comprehensive differential flush. For differential flush services, visit or call Northwest Automotive LLC in Defiance, OH 43512 today.

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 Northwest Automotive LLC 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 Northwest Automotive LLC, you can have the driveline serviced by experts.

Exhaust
In a motor vehicle, an exhaust system is a piping used to guide exhaust fumes away from the engine - usually to the rear of the vehicle. A properly functioning exhaust system not only sounds better, it is better - for you, your car, and the environment. Northwest Automotive LLC has expert technicians to service your car's exhaust system.

Shocks
Shocks (or shock absorbers) are mechanical devices designed to smooth out rough roads. The devices do this by converting kinetic energy to another form of energy. Properly working shocks reduce the effect of traveling over rough ground, leading to improved ride quality and vehicle handling. When shocks develop problems, driving on poorly leveled roads becomes unpleasant, and your vehicle may sway when turning. To have your vehicle's shocks diagnosed and repaired, visit Northwest Automotive LLC today.

Struts
Much like a shock absorber (shocks), your car's struts provide a dampening effect as you travel over a road's surface. By absorbing the shock of the road, struts allow passengers to ride in a car without constant and uncomfortable motion. Struts work a bit differently than shocks in that they provide structural support for your car's suspension. This means that struts support your car's weight, unlike shocks which only regulate the speed at which the weight is transferred. Struts usually last around 50,000 or 60,000 miles. This is simply because the damping characteristics of the parts gradually deteriorate over time. Call Northwest Automotive LLC at 419-782-7827 if you have questions about the struts on your car. Our expert technicians will diagnose any problems and help you make an informed decision about repairs.

Tires
As tires get older, they lose traction and deteriorate from the inside out, increasing the likelihood of a tire bursting. This can cause a rapid loss of control of your vehicle. To have a better performing vehicle, you need to make sure the tires are in good condition. For all your tire needs, contact Northwest Automotive LLC today.

What Our Customers Are Saying

Early Saturday morning, we were heading home to Minnesota and our car started making grinding noises. Called Tim and he said bring it in. Discovered we needed a new air conditioner compressor and he installed it and had us back on the road right away. It was a 12 hour drive home and we felt happy, cool and comfortable. Thanks Tim!


-Sharon Snyder

Extremely trustworthy and knowledgeable, with fair rates. Absolutely recommend this shop! You won't be disappointed.


-Jennifer Holman

My family has always gone to Northwest Automotive. We enjoy their great work, great deals, and friendly staff. I needed an alternator on an emergency. The shop owner found me an alternator after hours and willingly installed it to get us back on the road at a reasonable price. Always my first choice when recommending professional automotive repair.


-Sarah Doeden

Thanks so much for making our car safe, and doing it for an afforadable price.


-Madalyn Hasselschwert

Great service!


-Kevin Kaskel

The guys here are awesome! The fuel pump in my 99 Firebird went bad. They had my car towed to their place, diagnosed the problem, and had the fuel pump and the serpentine belt fixed within a few days. Will be recommending this place to all my family and friends!


-Jillian Graham

My daughter's car was making a horrible clacking noise from the engine. I trailered it to Northwest Automotive, and they took one listen and knew it was mechanical in nature. The worked really hard to quote a good price, find a used engine, and even offered to arrange financing. We chose not to repair the car at this time, and they didn't charge us for the effort they put in. I would definitely recommend these guys for any auto repair need.


-George Schaffer

My experience at Northwest Automotive has always been good. They have always gotten me in quickly and fixed whatever I needed for a reasonable price! I would definitely recommend doing business there. Specializing in engine repairs and all your other needs!


-Cassy Jennings

Our van's check engine light came on Friday evening. We planned to leave Sunday after church for vacation. So, Saturday morning I call up Northwest Automotive to see if they could fit me in. They said come on in. When I arrived, they ran the standard diagnostic test to find what tripped the light. It turned out to be an extremely simple fix, and they had me back on the road in 10 minutes, which was fantastic because I had two toddlers in tow. The best part? They charged me nothing! At dealerships, I've paid $50+ for them just to run this test.


-Eric Moquin

Great service and great guys that know what they're doing. And, they get it done fast and right!


-Justin Reed

Awesome work! These guys know automobiles and have all the professional tools to do any job, big or small. Take your vehicle in or give them a call. OUTSTANDING WORK!
