Signs of a bad rear hub: when is it time to replace it?

Wheel bearing on Octavia A5 designed for 100–150 thousand kilometers, but this period may be shortened due to aggressive driving, bad roads or low-quality spare parts. Here are the key symptoms that indicate wear:

• 🔊 Hum or howl from the rear wheel, increasing at speed. The sound may disappear when turning (due to load redistribution).
• 🌀 Vibration on the body or steering wheel, especially noticeable when braking. Often confused with wheel imbalance, the vibration from the hub does not disappear after balancing.
• 🚗 Wheel play when swinging it with your hands (checked on a jack). Even minimal play is a reason for replacement.
• 🔥 Hub overheating after the ride (you can check it with your hand - if the rim is too hot, this is an alarming sign).

If these signs are ignored, the bearing may collapse on the move, which will lead to a jamming of the wheel and an emergency situation. This is especially dangerous at high speeds. For example, on a highway at 120 km/h, a stuck wheel is almost guaranteed to cause a skid.
