The method depends on whether the race is pressed on the hub, seated in a bore, or retained by the bearing design. Use a puller or separator that grips the race itself, and replace bearings or seals when the vehicle manufacturer's procedure calls for it.
Determine whether the inner race stayed on the hub, an outer race remains in the hub or knuckle bore, or the bearing is a unitized assembly. Each condition needs a different contact point.
Secure the hub or knuckle so it cannot roll, tip, or load the puller sideways. Remove retainers and protect nearby sensor rings, studs, or sealing surfaces as the service procedure requires.
When the inner race has no shoulder for jaws, fit a bearing separator beneath it. Draw the separator evenly with a puller beam or press arrangement rather than prying against the hub flange.
For a race in a hub or knuckle bore, use the approved extractor, press fixture, or drift points specified for that assembly. Keep the load square to avoid scoring the bore.
Clean the seat and check for heat discoloration, grooves, cracks, or a loose fit. Damage at the seat can prevent a replacement bearing from seating correctly.
Pulling on rollers or a cage can break the bearing apart while leaving the race in place. Reposition the tool so force travels through the race being removed.
Measure race diameter, hub geometry, and available clearance before selecting jaws, separators, or drivers. DNT Tools can help review race-puller and separator requirements for wheel-hub service.
