What Causes Steering Wheel Wobble in Sedans?

[SanEverett]

The causes of steering wheel wobble in sedans are as follows: 1. Poor driving habits of the owner, such as excessive braking. 2. Twisted or deformed drive shaft, or lack of lubrication leading to rust and seizing. 3. Aging components in the suspension system. 4. Overly aggressive braking causing the brake discs and brake pads to overheat and deform. Below is some relevant information about steering wheel issues: 1. If the steering wheel vibrates intensely when driving at medium or higher speeds, accompanied by periodic abnormal noises from the chassis, it is likely due to an imbalance in the steering transmission mechanism. The drive shaft, spline shaft, or spline sleeve may be excessively worn. 2. If steering feels heavy and laborious, it may be caused by overly tight rolling bearings in the steering components, poor bearing lubrication, or tight or insufficiently lubricated ball joints in the tie rods. Additionally, insufficient tire pressure in the front wheels may also lead to this situation.
