Anti-Lock Brakes
Anti-lock brakes are designed to prevent wheel lock-up during rapid deceleration by automatically modulating brake pressure during emergency stops. This system allows wheels to maintain traction with the road while braking.

Failure of anti-lock brakes can elevate the risk of multiple vehicle crashes and run-off road incidents. To mitigate this risk, it is essential to have your anti-lock brake system examined and repaired by experts. At Thrash Automotive, our proficient technicians specialize in diagnosing and repairing faulty ABS systems, ensuring your safety.

Brakes
Brakes are mechanical devices designed to slow down or halt a vehicle, primarily through the use of friction. In essence, brakes impede your vehicle's motion, allowing you to stop whenever and wherever necessary. Brakes rank among the most critical vehicle components, and without them, you would be unable to bring your vehicle to a stop.

Chassis
The chassis serves as the internal framework of your vehicle, providing support for various components such as the wheels, engine, transmission, driveshaft, differential, and suspension.

A weakened or damaged chassis can lead to a weaker vehicle overall. To maintain a sturdy and properly functioning vehicle, it is crucial to have your car's chassis regularly inspected for defects.

Driveline
The driveline represents a vehicle section that connects the engine and transmission to the wheel axles. This component consists of powertrain parts excluding the engine and transmission.

A driveline failure translates to an immobilized vehicle, as energy cannot be transmitted from the engine to the wheel axles. To maintain your car's driveline in peak condition, inspections and servicing are essential.

Exhaust
In motor vehicles, an exhaust system consists of piping designed to guide exhaust fumes from the engine to the vehicle's rear. A well-functioning exhaust system not only sounds better but also benefits you, your vehicle, and the environment. Thrash Automotive in San Antonio has expert technicians ready to service your car's exhaust system.

Shock Absorbers
Shocks, or shock absorbers, are mechanical devices engineered to smooth out rough road surfaces. They achieve this by converting kinetic energy into another form of energy.

Properly functioning shocks minimize the impact of traveling over uneven terrain, leading to an improved ride quality and enhanced vehicle handling. When shock absorbers develop issues, driving on poorly leveled roads becomes uncomfortable, and your vehicle may sway during turns.

Suspension FAQs

How often should shocks be replaced?

Experts recommend that shocks be replaced at 50,000-100,000 miles. If you are a more aggressive driver or frequently drive on rough roads, they will wear out faster. Shocks don't go out all at once, they deteriorate slowly over time. If you are noticing problems with handling, making smooth turns or ride smoothness have one of the professionals at Thrash Automotive inspect your shocks.

Are struts difficult to replace?

Replacing struts is simple and fast for a professional. Replacing your front struts yourself is not recommended, especially if you need a new complete strut assembly kit. When you get your truck's struts replaced you also need to have the front-end alignment checked. Ask the professionals at Thrash Automotive to replace your struts and we will complete the work quickly and easily.

What is the difference between shocks and struts?

Shocks and struts are both parts of a vehicle's suspension system. However, each has a very specific job. Your vehicle has either shocks or struts. You cannot replace your shocks with struts and vice versa. Shock absorbers are hydraulic components that help minimize movement generated by the vehicle's springs. These springs absorb some of the jolts you might feel from uneven or damaged roads. Struts are structural components of certain vehicles' steering and suspension systems. They usually consist of a spring and a shock absorber. Struts are designed to be much stronger than shocks since they are designed for vehicles that carry heavy loads.

Is it necessary to get an alignment after strut replacement?

Thrash Automotive recommends performing an alignment anytime shocks, struts or other steering and suspension components are replaced. Getting your vehicle's alignment within factory specifications ensures optimal tire wear and helps prolong the life of your tires.

What happens if I only replace one strut or shock?

If you replace only one shock or strut, it will create poor handling when changing lanes or driving over bumps. If your car is new, replacing only one strut or shock absorber may be ok since the opposite side shock is not worn out yet. Generally, Thrash Automotive recommends replacing both shocks or struts.

Differential FAQs

Is it necessary to change front and rear differential fluid?

Over time, the differential fluid breaks down and becomes dirty and impacts performance. It is necessary to have your car or truck's differential serviced regularly. It is generally recommended to have the differential fluid changed every 40,000 to 60,000 miles. However, if you are a more aggressive driver you may need to get your front and rear differential fluid changed sooner. If you are in San Antonio, Castle Hills, Alamo Heights, Stone Oak or the surrounding area, give us a call and we can help you figure out what makes the most sense for your vehicle.

What is front and rear differential service?

Differential services performed by one of the professional technicians at Thrash Automotive usually includes draining the old fluid from the differentials and replacing it with new fluid according to the vehicle manufacturer's recommendations and specifications. Sometimes other components surrounding the differential may need to be serviced as well.
