Rack & Pinion Assembly failures are usually associated with high mileage wear or power steering pump & fluid contamination, and usually shows signs of hydraulic fluid leak, abnormal tightness at the steering wheel, or sometimes even grinding noises during normal steering. Your vehicle’s power steering rack is imperative to provide the ability to safely and easily steer the car. Electronic Power Steering (EPS) units are becoming the modern day norm with auto manufacturers. Unlike a hydraulic power steering system, an EPS system relies on a computer-controlled electric motor to operate – no longer needing assistance from an additional pump, fluid, belt, or pulley. But failures do occur within EPS systems, and it is highly encouraged to have it diagnosed by a professional right away should your EPS warning light illuminate. Mando Aftermarket offers brand new OE replacements rack & pinion & EPS units that are exactly like the one that originally came with your Hyundai or Kia – We Are OE!
