The top part of the truck is screwed to the deck and is called the baseplate, and beneath it is the hanger. The axle runs through the hanger. Between the baseplate and the hanger are bushings, also rubbers or grommets, that provide the cushion mechanism for turning the skateboard. The bushings cushion the truck when it turns. The stiffer the bushings, the more resistant the skateboard is to turning. The softer the bushings, the easier it is to turn. Bushings come in varying shapes and urethane formulas as well as durometers, which may affect turning, rebound and durability. A bolt called a kingpin holds these parts together and fits inside the bushings. Thus by tightening or loosening the kingpin nut, the trucks can be adjusted loosely for better turning and tighter for more stability (useful when landing tricks). Standard kingpin nut size is 3/8" - 24tpi. The position of the hanger respect to the baseplate is also determined by the pivot, a rod that slots into the corresponding seat in the baseplate. The pivot stops the hanger from rotating around the kingpin. The pivot must allow some movement around the bushings and therefore is not a perfect fit. The space between the pivot and its seat in the baseplate is filled by a pivot cup, a plastic part that will take most of the wear and tear of the pivot and assist in centering the hanger needs to be lubricated every so often.

Low ollies: This can happen for a lot of reasons, but the biggest one is that you are not crouching low enough before your ollie, and not pulling your feet high enough after you jump. When you crouch down, try and touch the ground. When you jump, try to hit yourself in the chest with your knees. Both knees. Don’t worry about falling. That will happen sometimes – that’s just part of skateboarding! For more help, read the How Can I Make My Ollies Higher? FAQ
So the proper foot placement for the ollie is with the ball of your back foot horizontal on the tail of your skateboard. And your front foot centered on your board right behind the front trucks. You may find that moving your feet around in different positions are more comfortable. This is fine, everybody can learn how to skateboard their own way.
