ABSTRACT:
A mechanical vehicle leveling device having a circular leveling bubble and four semicircular, mechanical measurement indicators revealed in a top cover unit of the device. The measurement indicators indicate the number of inches each wheel must be raised or lowered to level a vehicle. Four feet rotate the semi-circular indicators when the cover unit is manually adjusted relative to the base unit. The cover unit is adjusted to center the leveling bubble, whereby the movement actuates the four indicator scales to indicate whether to raise or lower each wheel by the indicated inches. A cam adjustment lever can be adjusted to compensate the indicators for wheelbase distance.
