What is the situation when surface rust appears on the vehicle's steering column?
2 Answers
Steering column surface rust could be caused by a water-damaged vehicle, or it might be due to the material itself—lack of rust-proof treatment or heat treatment, for example. Since the steering column is frequently in motion, friction is inevitable to some extent. Once the surface protective layer is damaged, rust is likely to form. Below are the characteristics of modern automotive steering columns: 1. Impact energy absorption. Many countries mandate that passenger cars must use energy-absorbing steering columns, which can deform during a collision to absorb impact energy and reduce driver injury. 2. Adjustable angle. The tilt angle of the steering column can be adjusted to accommodate drivers of different heights. Adjustment mechanisms come in two types: manual mechanical and electric. 3. Telescopic function. The steering wheel's front-back position can be adjusted like a telescope to suit drivers of different sizes. This also comes in manual and electric variants.
Surface rust on the steering column is actually quite common. I've encountered it myself after years of driving, likely because the car was frequently parked on damp ground or wasn't dried promptly after rain, allowing moisture to seep in and oxidize the metal surface. The steering column's low position makes it prone to splashes of muddy water, and over time, the protective coating wears off, leading to rust. While it may seem minor, rust can gradually eat into internal structures, causing stiff or unresponsive steering, which could lead to dangerous situations at high speeds. That's why I recommend regular inspections. For minor cases, simply sand the rust spots lightly and apply some rust-proof paint. If it's severe, take it to a repair shop immediately. Proper maintenance ensures peace of mind while driving.
