Front Axles and Vehicle Alignment Factors
This type of axle is mounted in front of the drive axles
What are the pusher axle(s)?
This is always measured when cold
What is Tire inflation pressures ?
This is the maximum air pressure an air spring is designed to contain
What is 200psi?
This design of tie-rod ends and tie-rod centers enables sharp turning radiuses without interference.
What is Dropped ?
This t is the strongest type of frame rail
What is an I-beam rail?
This type of axle is powered and can move the vehicle
What is the Live axle?
This is the primary determinant of tire inflation pressure.
What is the vehicle weight?
This is the movement of the suspension due to road bumps and terrain
What is Articulation ?
This force transmitted from the tires back through the steering system to the drive
What is road feel?
aluminum mixed with other metals to increase its strength.
What is Aluminum alloy?
This Center to center length is critical to maintain the same number or turns from center to the steering stops
What is a Drag link?
The tires at each position (steering, drive, trailer) all experience different.
What is rolling Resistance?
This is the weight of the vehicle components supported by the springs.
What is Sprung weight?
This movable electrical connection between the airbag and electrical system
What is the Clock Spring?
The flat areas at the top and bottom of the frame rail

This technique ensures the correct phasing of the steering column U-joints when being reassembled after servicing
What is match marking the steering shafts?
This usually caused by chronic overload or a section change in the frame rail, which causes a weak point
