Steering shkes at low speeds on 2001 Kia Sephia
Most likely wheel imbalance is causing the steering shake. Inspect that the tires are wearing even and or are safe to drive. Make sure the wheels are tight if you have just rotated the tires or had a tire off for any reason recently. A worn CV boot is axle related and should be replaced if the axle is still serviceable. A very badly worn wheel bearing can also give a shake but would be accompanied by bearing noise. Have the wheels inspected and balanced, it is cheap and will make the tires last longer.
