Electric power steering is also more tolerant of out-of-spec alignment settings, using software to recognize and compensate the steering pulling to one side. It's 25 seconds well spent! Some kits use all new parts, while others have recycled pieces. Hoses and belts need replacement, while seals in the pistons and pump will eventually age and leak. This made it hard to sense when a vehicle's tires were running out grip and starting to slip. https://www.facebook.com/AutoBodyRepairNetwork/, https://www.instagram.com/ptenmagazine/?hl=en, https://www.linkedin.com/company/40735491/, https://www.youtube.com/channel/UCxBEkpoYgmG0r34_B3mOr4Q. Each has its own unique benefits and drawbacks, so it can be difficult to decide which is the better option for your needs. . One important thing to note: Because the motor isn't designed to handle extremely high power for extended periods of time (for example, turning from lock to lock repeatedly while the vehicle is stationary), the EPS system will protect itself by limiting the amount of current commanded to reduce system temperature and unfortunately, limiting assist in the process. Electric power steering (EPS) is a type of vehicle steering system that uses an electric motor to assist in the steering process. Therefore, if you are driving a car with electric steering, it is important to be aware of the possibility that the electric motor could fail, and be prepared to take appropriate action if this happens.
