Q: What tools are required for the front bearing removal and installation process on Toyota Yaris?
A: A press, a suitable puller, or similar improvised tools will be required for this operation, and it is advisable to obtain a bearing overhaul kit before proceeding. Begin with the removal of the swivel hub, followed by a three-stage bearing removal process: first, remove the hub flange where the wheel mounts; second, tap off the inner race from the hub flange; and third, drive out the bearing itself from the hub. Start by removing the hub flange from the bearing/swivel hub assembly, preferably using a press, though a metal tube of suitable diameter or a puller can also be employed. Have an assistant hold the hub assembly over a work surface, then use a metal bar, tube, or socket to drive the hub flange through the bearing, which will destroy the bearing as the inner race separates from the flange. Next, remove the inner race left on the hub flange, ideally using a puller, or by gripping the flange in a vice and tapping the race off with a chisel, ensuring not to damage the flange's bearing surface. Tap the race at the top and both sides to prevent jamming. After that, remove the large bearing retaining circlip with circlip pliers, apply a generous amount of spray lubricant, and drive the bearing out using a large socket, ensuring the swivel hub is mounted securely to avoid damage. Clean off any burrs or raised edges from the hub flange and hub carrier with emery paper, then apply a light coat of lubricant to the inside of the hub carrier and the outside of the new bearing. Fit the new bearing squarely into the carrier, giving it light taps with a hammer to locate it, taking care to keep it square to avoid jamming. To press the bearing in fully without damage, use a length of threaded bar with a nut, large washers, and a drilled plate on the outside of the hub carrier, while using a large socket, another washer, and a nut on the inside, tightening the nuts to press the new bearing in place. Once the bearing is fully home, refit the bearing retaining circlip, and then press the hub flange into the new bearing using a similar method. Finally, refit the swivel hub.
