Vehicle Brake

The drivetrain is the system of components that generate the power to move your car or truck. When one of these components starts to malfunction or fail, it can have a dramatic effect on your vehicle’s performance. Signs of ailing drivetrain include rumbling, grinding or whining noises, transmission fluid leaks, uncommon tire wear, sudden vibrations when you shift gears and positioning problems. At PDA, we offer drivetrain solutions such as transmission service and flush, differential and transfer case service and part upgrades.

Services - Frontend Maintenance, repair & Alignments

Modern vehicles benefit from more precise and complex frontend systems than in the past, which means frontend components have become increasingly critical for your car’s overall performance.

Our mechanics can handle any frontend repairs you need, and we’re experts at wheel alignments, with state-of-the-art wheel alignment equipment.
