What are the symptoms of a bad car bearing?
2 Answers
Here are the specific symptoms of a bad car bearing: 1. When turning the steering wheel while stationary or at low speeds, a "squeaking" sound can be heard, and in severe cases, you may feel the steering wheel vibrate. 2. While driving, the tire noise becomes noticeably louder, and in severe cases, a "humming" sound may be heard. 3. When driving on bumpy roads or over speed bumps, a "thumping" sound can be heard. 4. Vehicle pulling to one side may also be caused by a damaged pressure bearing. Additional information: If the hub bearing is severely damaged, with cracks, pitting, or burn marks, it must be replaced. Before installing a new bearing, apply lubricant and then reassemble in the reverse order. The replaced bearing must rotate smoothly without any noise or vibration.
While driving, I noticed a humming noise near the wheels. At first, I thought it was tire noise, but the sound became increasingly noticeable, especially on the highway. When turning, the noise would change, sometimes turning into a rattling sound. Last week, when my speed exceeded 80, the steering wheel started to shake. I thought it needed wheel balancing, but the inspection revealed that the left front wheel bearing was loose. The mechanic said that bearing wear could cause the wheel to wobble, leading to irregular tire wear marks. If it completely fails, the wheel could lock up, which is very dangerous. Looking back now, there were slight abnormal noises a month ago, and I should have checked it then. Such problems shouldn't be delayed, as a bad bearing can accelerate damage to surrounding components, making repairs more expensive.
