Fabrication is the use of machines, tools and labour to produce goods for use or sale. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. Such finished goods may be used for manufacturing other, more complex product.[2]

What is a pitman arm?
The pitman arm is also called steering arm, it is a linkage which is attached at one side to the steering box (through sector shaft) at the bottom of the steering wheel shaft and on the other side to the track rod which is attached at the other end to the idler arm. When the steering wheel is turned left or right, a worm gear at the bottom of the steering shaft turns a set of teeth. That action moves a gear that activates the pitman arm, causing the steering linkage to move the wheels. [8] The steering arm is part of an older recirculating ball steering system which is still used primarily in some full-size SUVs and trucks as compared with the smoother-handling rack and pinion steering mechanism more commonly used in automobiles. A properly functioning pitman arm, 1) precisely directs the movement of all the other steering links, 2) limits wheel wobble on bumpy surfaces, 3) assures full wheel turning radius and 4) helps to reduce steering wheel vibration. [8]
What is Pitman arm?
