Parts for your 2002 Ford Ranger-Wheel hubs

2002 Ford Ranger wheel hubs: what they do and when to service or replace them

Based on the Ford Workshop Manual (WSM, suspension/brake sections for 1998–2011 Ranger), Ford parts catalogues, and bearing maker application data (e.g., Timken and NTN), the 2002 Ford Ranger is fitted with wheel hubs. Two-wheel drive models use a serviceable hub/rotor setup with tapered roller bearings, while four-wheel drive models use a bolt-on, unitised hub and bearing assembly that often integrates an ABS tone ring. There’s no scenario on this model year where a wheel hub isn’t relevant to keeping the wheels on and rolling true.

The hub’s job is simple but critical: it carries the ute’s weight, keeps the wheel centred, allows smooth rotation via the bearings, and on ABS-equipped models provides the signal ring for the wheel speed sensor. On 4x4 Rangers, the front hub is splined to the CV stub axle, for this generation there’s no manual “locking hub” at the wheel—engagement is handled via the driveline, but the wheel hub/bearing unit is very much there doing the hard yakka.

Servicing depends on drivetrain:

• 2WD front hubs: These use inner and outer tapered roller bearings packed with high-temp wheel bearing grease. During brake work, it’s good practice to clean, inspect and repack the bearings, fit a new grease seal, adjust bearing preload correctly (snug, then set endplay as per WSM), and install a fresh split pin. Any pitting, blueing or roughness means replacement bearings and races.
• 4WD front hubs: These are sealed, non-serviceable units. If there’s play, a growl that follows road speed, ABS faults tied to a wheel, or heat at the hub, replace the assembly. Clean the knuckle face, use new mounting bolts if specified, and torque the axle/stub nut to the service spec—no rattle-gun heroics. A wheel alignment check after hub replacement is a smart move.

Rear ends use axle bearings at the housing ends, noises from the back aren’t a “front hub” issue and should be diagnosed separately.

Tell-tales of a crook hub include a droning hum that changes in corners, free play at 12 and 6 o’clock, ABS light on, or uneven tyre wear. Quality parts, correct torque, and a road test are the go. After 100–200 km, recheck wheel nut torque. If one side has failed at high kilometres, doing both sides can save a repeat visit.

Popular questions

Does a 2002 Ford Ranger have locking hubs?
Most 2002 4x4 Rangers don’t use manual locking hubs at the wheel. They run a constant front hub/bearing with driveline engagement handled via the transfer case. That said, there’s still a proper wheel hub assembly up front—just not a user-operated locking mechanism. 2WD models, of course, have no locking hubs.

Can the front wheel bearings be greased on a 2002 Ranger?
Yes for 2WD: they use serviceable tapered roller bearings that should be cleaned, inspected, repacked and adjusted during brake servicing. No for 4WD: the front hub is a sealed, unitised assembly. If it’s noisy or loose, the fix is replacement of the whole hub unit.

Should both front hubs be replaced at the same time?
Not mandatory, but it’s often sensible at higher kilometres. If one side has failed or the noise is hard to isolate, replacing hubs in pairs can balance wear and reduce downtime. Always confirm with a proper test drive and on-vehicle diagnosis first.
