How do you measure caster angle on a car?

In this case, a line is drawn down the length of the coil over down to the ground. A second line is then drawn vertically down the centre line of the wheel. Again, this is done in 2D from the side view of the car. The angle between these two lines is the caster angle of that wheel.

How do I know if my car has a caster?

See all 10 photos Caster is viewed from the side of the tire. Positive caster is when the top of the spindle is tilted backward toward the rear of the car, as in the photo. Negative caster is when the top of the spindle is angled toward the front of the car. Positive caster is always preferable.

How do you measure caster with an angle finder?

Turn the steering wheel right until the wheel is turned 20 degrees right of straight ahead (turning 40 degrees total). Hold the gauge at a 90-degree angle and the reading will be your caster angle for the left wheel.

How can you tell if caster is off?

How do you calculate caster?

From Formula Magazine:

1. Turn wheel 15 degree left of center and take a camber reading.
2. Turn the wheel 15 degrees right of center and take acamber reading.
3. Multiply the difference x 2 and that is your castor.
4. When turning from outside to inside a neg camber change equals positive castor.

The diameter is measured with the wheel lying flat on its side, and with a measuring device measure from one side of the wheel to the opposite side. If the wheel is 8”, then the caster is considered a 8” caster. It’s important to make sure the measuring device passes over the center of the wheel.

How to calculate a caster angle?

How to Calculate a Caster Angle Park the vehicle with the front wheels on the turntables (set to zero). Point the wheels straight ahead. Attach the gauge to the right front wheel hub. Turn the steering wheel 20 degrees right. Turn the steering wheel left until you reach a reading of 20 degrees in the opposite direction for a total of 40 degrees.
