MDA is a man-made (synthetic) recreational drug noted for its stimulant and psychedelic properties that has been used since the 1960s as a clubbing and sex-enhancing substance, with some similarities to LSD and MDMA (ecstasy). Sought after effects. 1  visual hallucinations.
A wheel alignment is done to make sure the vehicle's wheels are running parallel to each other, and that the tires meet the road at a correct angle, to fix or avoid problems such as irregular tire wear, poor handling (pulling to one side) or a crooked steering wheel.
I bought a service contract for alignment at my local tire store and every time I take my SUV in for my 5,000-mile alignment they tell me I need to have the tires balanced and rotated. I know the steering wheel shakes when the tires are out of balance, and when it's out of alignment, the car pulls to one side.
