All 1 Known Issues
On the 2000-2007 Ford Focus, 1999-2007 Ford Focus (1st-generation Mk1 and Mk1.5) suffer from repeated rear wheel bearing failures, often within months of replacement. One Focus Fanatics owner reported the left rear wheel bearing failing 4 times in 7 months. Root cause is missing or degraded inboard spindle seals that allow brake dust and water into the bearing race, plus alignment drift (excessive negative camber or toe) accelerating wear. Ford acknowledged the seal design in owner communities but never issued a formal recall. Replacement requires the full hub assembly. The 2012-2018 Mk3 Focus has separate bearing issues with different root causes (not covered by this entry).
Common Symptoms
- Humming or growling noise from rear wheels that increases with speed
- Rumbling noise that changes pitch when turning (load shifts off bearing)
- Vibration felt through vehicle floor
- Uneven rear tire wear
- ABS warning light if bearing play affects wheel speed sensor
- Loose or wobbly feeling in rear end
- Grinding noise from rear at highway speeds
How to Fix
Replace the rear wheel bearing/hub assembly as a complete unit - the bearing is sealed and non-serviceable. RepairPal estimates $317-429 per side. When replacing, clean the knuckle bore thoroughly and apply anti-seize compound to prevent the new bearing from seizing in the housing (makes future replacement much easier). If the vehicle is in a salt-belt state, replace both rear bearings simultaneously - the other side will likely fail soon after.

Parts and tips from 2,200+ owners who fixed this issue
- TipWhen replacing rear wheel bearings on a Focus, apply anti-seize to the hub-to-knuckle bore interface. Many Focus owners report that the bearing seizes into the knuckle from corrosion, making future replacement a nightmare without anti-seize.
- TipTimken or SKF bearings are the most recommended aftermarket brands for Focus rear wheel bearings. Cheap no-name bearings from Amazon have extremely high failure rates - some Focus owners report failures within 10,000 miles on cheap units.
