Q: How to replace the front wheel bearing in the center hub assembly on 2015 Nissan Juke?
A: The bearing is part of the centre hub assembly and can only be replaced as a complete assembly. To begin removal, firmly apply the handbrake, jack up the front of the vehicle, and support it securely on axle stands before removing the appropriate roadwheel. Next, remove the brake disc and unbolt the ABS wheel speed sensor, suspending it away from the working area to avoid damage. Disconnect the outboard end of the driveshaft from the hub carrier, ensuring not to drain the transmission oil or disconnect the inboard end; support the end of the driveshaft to prevent it from hanging down. Undo the two upper hub carrier-to-strut retaining bolt/nuts and remove the hub carrier from the strut, noting the fitted position of the retaining bolts for refitting and discarding the nuts. Slacken the four hub/bearing retaining bolts, remove two completely, and leave the other two mostly screwed into the rear of the hub/bearing. Using a copper hammer, hit the heads of the two remaining bolts while holding the assembly on the bench; if the hub/bearing is reluctant to move, apply releasing fluid and let it soak before trying again. Once the hub/bearing is removed, take off the brake disc back plate, noting its fitted position. Consult a Nissan dealer to determine if the new bearing comes complete with the centre wheel flange or separately; if separately, press the centre wheel flange out from the old bearing. Be aware that one half of the bearing inner race may remain on the centre wheel flange; if so, support the wheel hub in a vice and draw off the inner race using a suitable puller. For refitting, clean the wheel flange, hub, and bearing location in the hub carrier thoroughly before pressing the new bearing onto the centre wheel flange until it contacts the shoulder. This can be done using metal tubing or large sockets with threaded bar, spacers, and nuts. Once the bearing is fully seated, fit the brake disc back plate and then the hub/bearing unit to the carrier, tightening the retaining bolts. Refit the hub/bearing carrier to the lower part of the strut, securing it with the noted retaining bolts and new nuts, and tighten them to the specified torque setting. Reconnect the outer end of the driveshaft to the hub, reinstall the wheel speed sensor, and then refit the front brake disc. Finally, complete the process by refitting the roadwheel and lowering the vehicle to the ground.
