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).
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.

On the 2000-2007 Ford Focus, the first-generation Focus ignition lock cylinder uses soft aluminum wafers and a side-bar design. With normal use the wafers and the cylinder sidewall deform, the key cuts grooves into the housing, and eventually a wafer sticks out of position. The key then will not insert fully, will not rotate, or will not come back out of the cylinder, stranding the car. It is one of the most frequently reported mechanical failures on 2000-2005 Focus models and continued in a milder form on later cars. Owners note the original-style cylinder (keyhole offset from center) is the failure-prone version; the revised cylinder has the keyhole centered.
Before replacing anything, try tapping the end of a fully inserted key with a screwdriver handle while applying light turning pressure - this frequently frees a stuck wafer. For a permanent fix, replace the ignition lock cylinder with the revised centered-keyhole cylinder (or a Strattec unit without the side bar); a dealer will key a new cylinder to the VIN. If the cylinder is completely seized, it can be drilled out to get the steering lock released. Note that PATS transponder keys still need to be programmed to the car if the key changes.
