This pack contains four 5x10 bearings intended for use in the steering hubs and knuckles of HPI Baja scale RC cars. They are supplied to replace worn bearings that introduce steering play or binding, improving wheel reaction and handling predictability on mixed surfaces.
Simple installation: take off the steering hubs or knuckles, press or push out the old bearings, then install the new 5x10 bearings into the bores. Refit components and verify free rotation and minimal side-to-side play. Remove grit from mating parts before final assembly to ensure correct seating.
Performance note: replacing bearings reduces internal friction and slop in the steering train, helping the driver keep consistent steering input during track sessions and bashing alike. Periodic replacement is a low-cost maintenance item to preserve steering feel.
