Rely on A.G. Automotive & Diagnosis in Reseda, CA 91335 to provide quality care for your vehicle's undercarriage. Stop by our shop to see how we can help you or call 818-578-5191 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 A.G. Automotive & Diagnosis.

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 A.G. Automotive & Diagnosis, 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 A.G. Automotive & Diagnosis's quick lube services, you will have a brake system flush performed by brake experts. Call 818-578-5191 or visit A.G. Automotive & Diagnosis 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 A.G. Automotive & Diagnosis 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 A.G. Automotive & Diagnosis, 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 A.G. Automotive & Diagnosis in Reseda, CA 91335, 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 A.G. Automotive & Diagnosis in Reseda, CA 91335 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 A.G. Automotive & Diagnosis 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 A.G. Automotive & Diagnosis, 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. A.G. Automotive & Diagnosis 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 A.G. Automotive & Diagnosis 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 A.G. Automotive & Diagnosis at 818-578-5191 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.

My Dodge Cummins Diesel pickup suddenly started running rich and misfiring, had it towed to AG Automotive after talking to Chuck about the problem. He worked on it and found that the injector pump gear was bad, they never go bad but mine did and Chuck found and fixed it. My pickup runs great I will definitely recommend AG Automotive to others.

It's simply the best service shop I've been to. Professional and courteous staff. I Had some serious issues with my engine, tried 2 other shops prior A.G. and they couldn't solve the problem. Chuck diagnosed my pickup truck, found the problem and fixed it in a timely manner. For a reasonable price, too!

A&G Automotive did an awesome job on my mini. Fast and efficient service. Fair pricing. They get straight to the point. I'll continue to bring my car to here for maintenance and recommend them to all my family and friends. Thanks A&G


reviewicon
I had an oil leak and I could have been taken advantage of very easily...but they were honest and told me it was a simple fix, and I walked out paying less than originally quoted. I understand every business has to make money to strive, but I can see they value their integrity over making a quick buck. They've gained my respect and future business. I highly recommend this company!


reviewicon
I found this AG Automotive through yelp. So I decided to give it a try. I sent in one of our inventory (2006 Ford Crown Victoria Police Interceptor) in for steering wheel stiffness diagnostic. Owner Chuck was able to identify the problem in the first place. His crews are very professional (more professional I thought I was at a car dealership service department). Great experience throughout. Most importantly, got the job done right. They know what they're talking about. Certainly not some BS mom & pop shop just there for your money (if they fixed it right the first time). Price is fair. If you ever have problem with the repairs they done, there's always a warranty to back you up. Thank you chuck. I will be back at your shop for our other vehicle recondition. From: Ideal Motor Group in San Gabriel Valley.


reviewicon
I went here with a really bad brake problem. Chuck took the time to explain the cause of the issue and what could be done to not only fix it but how to prevent it in the future. He and his team are professional and highly knowledgeable. I feel confident and grateful to these guys. I definitely recommend this shop and will continue to refer friends and family here. His prices are more than fair and the work is top shelf.
