What Are the Reasons for a Heavy Car Steering Wheel?
2 Answers
Car steering wheel heavy reasons are: 1. Insufficient tire pressure; 2. Contaminated power steering fluid; 3. Internal failure of the power assist system; 4. Poor bearing lubrication. Solutions for a heavy car steering wheel include: 1. Replenishing hydraulic power steering fluid; 2. Replacing circuit fuses; 3. Replacing flat bearings and adding kingpin grease; 4. Increasing lubrication for the steering tie rod ball joints. Steering wheels are categorized into: single-spoke, dual-spoke, triple-spoke, and quad-spoke steering wheels. Their working principle involves transmitting torque to the rack and pinion mechanism, thereby enabling the wheels to turn left or right.
I've been driving my own car for long distances, and the heavy steering wheel issue is really a headache, with many common causes. First, check the power steering system. For hydraulic systems, if the power steering pump fails or the belt slips, the pressure won't build up, making the steering wheel heavy; leaking fluid in the hoses can also cause power steering failure. If the tire pressure is too low or the tread is worn out, the resistance when turning increases significantly. Another example is wear in the steering mechanism's ball joints or tie rods, which can cause mechanical jamming and make the steering wheel stiff. I've experienced particularly heavy steering in winter when the fluid froze, and not addressing it promptly could lead to accidents. It's recommended to have the technician check the fluid level and system pressure during every maintenance session, and simply inspect the tire pressure before each trip to avoid a lot of trouble.
