Wheel beating (Mitsubishi Colt 4)

To measure the value of the wheel runout, use a dial indicator. In this case, the wheel can remain on the car or be dismantled. In the latter case, the wheel must be secured to the hub, for example, on a balancing stand. Measurements are taken on the wheel with the tire removed or installed. Radial and axial runout are measured on the inner and outer sides of the wheel rim. The indicator must be firmly secured to a fixed support. The runout is measured by slowly rotating the wheel, according to the indicator readings for one wheel revolution. If the runout value is outside the permissible limits, or the wheel vibration cannot be eliminated by balancing, the wheel must be replaced. When measuring the runout, do not take into account errors introduced by unevenness of the wheel surface (welded seams, paint smudges, scratches, etc.).

Steel wheels: radial runout - 0.8 mm; axial runout - 1.0 mm.

Aluminum wheels: radial runout - 0.7 mm; axial runout - 0.8 mm.
