Wheel Bearing
Typical layout and location for the Wheel Bearing assembly.
Symptoms
- Humming, droning, or roaring noise from the wheels that increases with road speed
- Noise changes pitch or disappears when turning slightly left or right
- Slight vibration felt through the steering wheel at motorway speeds
Root Cause
The sealed bearing unit loses its grease over time, or water ingress causes the steel balls/rollers to pit and rust. Impact damage from potholes can also cause a flat spot on the bearing race.
How To Fix
- Jack the car up and check for play by rocking the wheel at the 12 and 6 o'clock positions.
- Spin the wheel and listen for a rough rumbling sound.
- Press out the old bearing and press in a new OEM-quality bearing (e.g. SKF, FAG, SNR).
- Cost: £120-250 per corner

Other Faults on This Variant
Oil Pickup Strainer Blockage and Engine Seizure
CriticalA fatal flaw in the Mazda 2.2 MZR-CD engine. Injector seals leak, allowing carbon into the oil sump which blocks the oil pickup strainer. The engine then seizes from oil starvation.
Air Conditioning Condenser Leak (Stone Damage)
MinorThe air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
Front Anti-Roll Bar Drop Link Wear
MinorThe front anti-roll bar drop links wear out on heavily potholed UK roads, causing an annoying knocking sound at low speeds.
