Vehicle maintenance: Causes of heavy steering and tire cracking

Automotive maintenance guides highlight common causes for steering and tire issues in vehicles.

Heavy steering during parking or low-speed maneuvers can stem from problems within the power steering system, such as the rack steer or steering shaft. In hydraulic systems, contaminated or low fluid levels, leaks in hoses or seals, and excessive pressure caused by holding the steering wheel in a full lock position can impair performance.

Additionally, car tires can develop cracks even if the vehicle is rarely driven. Rubber aging is driven by exposure to ultraviolet rays, heat, ozone, and oxygen. Experts suggest that tires should be inspected professionally after five years of use and replaced after ten years, regardless of tread depth. Tire age can be determined using the DOT code on the sidewall, which indicates the week and year of production.
