Raise the front end clear of the ground. Make certain that the control cables aren’t binding the forks, and that no accessories impede the fork’s ability to turn freely. With the wheel in the straight-ahead position, check the bearings for play by grasping the lower fork legs as close to the axle as possible and giving them a push and a pull. If any play is felt, the bearings definitely need adjusting, as does your maintenance program. No play? Good, gently turn the bars from side to side. The forks should move smoothly without binding in any position. If the bearings feel like there is a notch or dent in them, they’ll need to be replaced ASAP. Typically, the dent will be most apparent in the straight-ahead position; in a worst-case scenario, the bearings will actually feel as if they’re dropping into a detented position.
