Use the following readings and specifications to answer the eight questions below.

Readings

	Left Front	Right Front
Caster	3.250	4.250
Camber	10	–0.25
Toe	0"	0"

Specifications

	Limits
Caster	30 + 10
Camber	0.50 + 1/20
Toe	1/16 – 3/16 inch toe in

1.  Since the vehicle pulls towards the side with the most negative caster, which way will the caster make this vehicle pull?

2.  Since the vehicle pulls towards the side with the most positive camber, which way will the camber make this vehicle pull?

3.  How many degrees and in which direction does the left wheel have to move in order to correct caster?

4.  How many degrees and in which direction does the left wheel have to move in order to correct camber?

5.  How many degrees and in which direction does the right wheel have to move in order to correct caster?

6.  How many degrees and in which direction does the right wheel have to move in order to correct camber?

7.  How far and in which direction does the left wheel have to move in order to correct toe?

8.  How far and in which direction does the right wheel have to move in order to correct toe?

Solutions:

1.  Most negative is the one closest to the negative number on the number line. Left
2.  Left.  Only one positive number.
3.  Don't move.  It is in specs.
4.  Don't move.  It is in specs.
5.  0.25⁰  less (negative).  Range: 2-4 degrees.  4.25 - 4.00 = 0.25
6.   0.25⁰ more (positive).
7.  1/16" (positive).
8.  1/16" (positive).
