Undercar Services: Maintenance & Repair

Superior Auto Service Center approaches caring for your car or truck from the ground up. That means that before we look over the internal components of your ride we take time to make sure that you're working with a solid foundation. Our comprehensive undercar inspections and services cover an important area of your car that can easily be neglected and give the foundation of your vehicle the care and attention it deserves.

Avoid disaster by coming in a having your undercarriage checked out today. Call us at 301-682-3533 or visit us in Frederick, MD so we can schedule an appointment to ensure your car is in tip-top shape!

Our competitively priced undercar services include:

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 Superior Auto Service Center.

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 Superior Auto Service Center, we have anti-lock brake experts who will examine and repair your faulty ABS - keeping you safe.

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 Superior Auto Service Center can work on your car's brakes to ensure you have a safe drive.

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 Superior Auto Service Center's quick lube services, you will have a brake system flush performed by brake experts. Call 301-682-3533 or visit Superior Auto Service Center today.

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 Superior Auto Service Center, there are experienced undercar service providers who can work on your chassis.

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 Superior Auto Service Center today for differentials examination and servicing.

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 Superior Auto Service Center in Frederick, MD 21703 today.

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. Superior Auto Service Center has expert technicians to service your car's exhaust system.

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 Superior Auto Service Center, you can have the driveline serviced by experts.

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 Superior Auto Service Center today.

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 Superior Auto Service Center today.

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 Superior Auto Service Center at 301-682-3533 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.

What Our Customers Are Saying

I've got 3 cars and I take all of them there when work is needed. These guys are thorough and honest! I've been a customer since 2006.

-Tom L

Fantastic and Honest people that go above and beyond to help you... Can't recommend them enough...

-Lenny A.

The best customer service, transparency and honesty I have ever experienced when working with an auto repair shop. They will be upfront, and go the extra mile. My vehicles will never be serviced elsewhere.

-Daniel K.

I have been with Superior for 3 years with my 2001 Jeep. They do all my work and I am 100% satisfied with they work and I like the way I'm treated, not like a customer but a good friend. They show me what is wrong so I don't have to take their word for it. If I need a ride home or be picked up to get my car they are there for me. I think I'll be with them for many more years.

-Tom R.

Absolutely the Best! Superior and the team is like family, trustworthy, a clean shop and a pleasure to work with. As a single lady, choosing a good mechanic can be daunting. I don't even want to take my truck anywhere else. The guys at Superior drove my vehicle with me and listened for problems. They described the problem to me so that I could really understand, and their service was fast! They will help with regular maintenance so I won't have to worry about missing important upkeep. They really are SUPERIOR!

-Diana O.

Very knowledgeable and honest guys. Was able to get an estimate before the work was even done. Very friendly. Pricing is not the cheapest around town but reasonable (There is also the old adage you get what you pay for). Would recommend and will do business with them again!

-Timothy W.

These guys are awesome! I was treated like family from the minute I walked in the door. They listened to my concerns, gave me a detailed description of what was needed, found other maintenance concerns, gave me a detailed estimate and even told me what could be differed until next time. Integrity comes to mind when I think about my experience. You can trust these folks with your ride. Highly recommended!

-Mac C.

These guys rock. Recently I started my car (while parked in the garage) and it was leaking fuel. Then, died on me. After calling these guys, within two hours they arranged to have the car towed and by that afternoon provided me with an update. The next morning they called with an estimate for the repairs. Ironically, this happened the DAY BEFORE I left for vacation. Not only did they provide amazing service from the very beginning, but they took care of the repairs and the car was ready for pickup upon my return. This gave me peace of mind while I was away. They even came to my house to pick me up to get my car when I returned! Reasonable prices for work performed (replaced fuel filter, PCV valve, etc.) and the car's been running smoothly ever since. So happy with Superior and highly recommend them.

-Nicole R.

I just want to say that Superior Auto Services are awesome! They have a great professional team. They always greet you with a smile and work around your schedule. Usually it is the same day service. One time I was there I was having a problem with my Subaru acting like it wanted to shut off but not all the time. They drove the car 13 miles before it would act up. How many auto services would do that.? Probably zero to one. I highly recommend them to anyone!! I will never take my car anywhere else. Also they were highly recommended to me. Thanks for keeping my Subaru running greatly appreciate everything you have done for me!!!!

-Margaret H.

After living in the Frederick area for several years I was happy to find Superior! I was coming off an experience where getting my oil changed at a high volume oil change business didn't tell me I needed an alignment and had to purchase a new set of tires prematurely. Superior has great customer service. I really appreciate the time they spend explaining repairs and repair options. I appreciate and use their shuttle service. I appreciate that they are a full service shop and can take care of any repairs my cars need. The only small nit I have is that their price on parts can be a bit high. I also appreciate that their price for an oil change/tire rotation is reasonable- that's big for me!

-Ben L.

If I can take my car there..... you can to, because I'm picky.

-Travis P.

Outstanding in every way, couldn't be more pleased, they live up to their name. Will be a loyal customer from now on; highly recommended.

-Diane D.

Dealer service can be frustrating. So when that happens try Superior Auto Service just off of English Muffin Way. They're friendly, courteous and thorough. Reasonable pricing too. Got that at your dealer? Just a thought!

-Mike M.

Excellent shop, highly recommend. I went into the shop on MLK day around 10:30am to inquire about having an aftermarket exhaust I had purchased installed. They said as long as everything lines up and no issues, 1 hour labor, they scheduled me for the next day. Next day I dropped it off in the morning and picked it up at the end of the day, same price I was told 1 hour of labor. These guys did a great job and were able to fit in my exhaust without needing to wait a long time for an appointment. They also have a shuttle service that dropped me off at work and picked me up when the car was ready. I know where I will go when I have other automotive needs, go there with confidence.
