Preventative Maintenance

Preventative maintenance is key when it comes to a healthy and reliable car. Some items can fail without warning, such as an alternator or a window regulator; but others have serviceable life spans recommended by the manufacturer, like transmission oil or a PCV valve. We perform a courtesy inspection of every vehicle that visits Auto Stop in Falls Church to help you stay on top of your car’s preventative maintenance – translating to more time spent on the road and less time at the repair shop! The picture below shows a serpentine belt from a 2000 Chevy Blazer on its “last leg,” with cracked and missing ribs. Through our 25 point inspection we can assist in prioritizing and planning for repairs, because an informed customer is a happy customer!

Why is my car making a clunking noise?

A control arm bolts in-between the vehicle frame & steering knuckle and allows the axle to travel up and down with the suspension. These metal arms incorporate rubber bushings and a metal ball joint to absorb bumps and stabilize vertical axle movement. Over time, the joint and bushings can wear down and develop excessive play. This leads to a variety of symptoms including: clunking noise over bumps, clunking noise during hard turns, vibrations in steering wheel, pulling to one side, or aggressive tire wear. The picture below shows a control arm bushing on a Nissan Altima that developed cracks and was not performing optimally. If you hear a clunking noise over bumps or notice a difference in steering, bring your vehicle in to Auto Stop in Falls Church to have an ASE Certified Mechanic diagnose your symptoms. #autorepair #fallschurchva #fallschurch #autostop #maintenance #suspension

An object in motion stays in motion unless acted on by an external force.

- This is part of Newton’s First Law of motion and at face value it says a car would never come to a stop without brakes on an infinitely flat road. Obviously, there are a few control variables we are leaving out (rolling resistance, headwind) but you get the idea. If we are going to take our cars up to high rates of speed, we need to be able to bring them back to a stop. The brake line on this Mazda was leaking brake fluid at the caliper and would eventually lead to an unresponsive brake pedal if the fluid continued to deplete. Brakes are critical components to our daily commutes! For this reason, all of us at Auto Stop in Falls Church VA take brakes very seriously and we inspect them on every vehicle as part of our 25 point courtesy inspection. Bring any of your braking concerns or needs to our ASE certified mechanics in Baileys Crossroads.

The steering rack in your vehicle is where all the magic happens when you grab hold of your steering wheel. It takes user input and moves the front wheels left or right so you can pull in the parking spaces at the mall or avoid that pesky pothole in the road. As you might imagine there are a lot of moving parts sealed inside this rack, and it’s important that they receive adequate lubrication and protection from outside elements. There are collapsible rubber ‘boots’ (like that of an accordion) on either side that extend or compress during turns. However, these boots often tear and allow debris to get into the system. Once the torn boot is discovered, it is usually recommended to replace the rack, as it can be difficult to predict the condition of the entire system. If you are having problems with your steering system, call the auto repair experts at Auto Stop, conveniently located near Falls Church, Arlington, and Alexandria Va to have your vehicle inspected by our ASE certified mechanics.

Would the top one still spin after being run over?

Why are my brakes grinding?

Most modern braking systems incorporate a disc rotor that spins with each wheel and brake pads that are held over the rotor. When you push the brake pedal, these pads hug the spinning rotor and slow the wheels. If the brake pads get worn too low the pad material will eventually wear away and the metal base of the pad will grind against the rotors, creating a metal on metal grinding noise. This scores and destroys the rotors, and can also damage the brake calipers (the device that applies the pads) – which tend to be expensive to replace. If your brakes are making a grinding noise, bring your vehicle in for one of our ASE Certified mechanics near Falls Church Alexandria and Arlington Va to perform a free brake inspection! #autorepair #arlingtonva #alexandriava #fallschurchva #brakes #autostop

My differential is leaking fluid!

The job that a differential performs is not a glamorous one, in fact if the TV show Dirty Jobs had an episode on cars, the differential would be a prime candidate! The differential sits in between the front or rear wheels and houses several gears that transfer rotational energy from the driveshaft to those wheels. The steel gears produce a lot of heat, so they are lubricated and cooled with heavy gear oil. Overtime the seals/gaskets around the differential can deteriorate and begin to leak this crucial oil, which could lead to very costly repairs if the gears are starved of proper lubrication. Pictured below is a differential with a considerable leak emanating from the pinion seal. If you need differential service near Falls Church, Arlington, Alexandria Va or notice your differential is leaking, bring your vehicle to the experienced mechanics at Auto Stop! #fallschurchva #arlingtonva #alexandriava #autorepair #autostop

Do I need to replace the belts on my engine?

Your vehicle has multiple accessories that are powered by the engine – these include your air conditioner compressor, alternator, power steering pump, water pump, and radiator fan. Most, if not all these components, are powered through a serpentine or accessory belt located on the front of the engine. These belts work under high tension whenever the engine is running, so it’s not uncommon for these to develop noise given the right wear and circumstances. However, just like any other rubber component, these belts can dry out and crack over time, so they should be replaced within a certain maintenance interval to prevent them from failing on the engine – which would render the vehicle inoperable. The picture below shows a belt with cracks developing in the interior ribs. When you see a belt in this condition, it is reaching the end of its serviceable life and should be replaced immediately. Bring your vehicle to the auto mechanic at Auto Stop conveniently located in Bailey’s Crossroads to serve Falls Church, Arlington, and Alexandria Va and we will inspect the condition of your serpentine / accessory belts. #fallschurchva #arlingtonva #alexandriava #autorepair #autostop

Axle repair near me?

An axle has the important job of transferring power from the drivetrain to the wheels. Front wheel drive (FWD) vehicles utilize either u-joints or constant velocity (CV) joints, which are the weakest points in an axle and are usually the first to fail. However, we recently replaced an axle on an Acura TL that had sheared at the central shaft – one of the strongest points in an axle’s design. This specific axle used a rubber dampener that balanced the shaft under heavy acceleration. Upon inspection, our technician noticed heavy corrosion between the dampener and the axle that resulted from trapped moisture. In the picture below, you can see the red arrow pointing to the large areas of corrosion around the axle, and the yellow arrow pointing to the remaining inner axle shaft that inevitably sheared under load. The larger the diameter of an axle shaft, the more torque it can withstand – so with corrosion decreasing the diameter of this axle, it caused it to shear under heavy acceleration. For any axle repairs, our mechanics in Falls Church Va can have you back on the road in no time! #fallschurch #alexandria #arlington #autorepair #autostop
