The most favorable way to adjust your caster angle is to
install a set of adjustable front upper and lower control arms
. The lowers would be used to reposition the axle properly under your Jeep and the upper control arms allow you to set the caster angle.
How do you find the caster angle on a Jeep?
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 do you adjust Castor?
With the bubble gauge installed on the hub, turn the tire inboard 20 degrees and level the gauge. Using the
center caster adjustment knob underneath
the gauge, zero the caster reading. Now turn the tire 20 degrees out and the gauge will read the amount of positive or negative caster.
How do you tell if your caster is off?

How do you adjust caster alignment?
A safe starting point for caster is
2 to 3 degrees of positive caster

Do you adjust caster or camber first?
With front-end alignments,
correct caster and camber adjustments first
. Certain FWD vehicles do not offer caster adjustments, but correcting the camber may bring the caster within specs.
How does caster affect steering?
Caster. … Increasing the amount of positive caster will
increase steering effort and straight line tracking
, as well as improve high speed stability and cornering effectiveness. Positive caster also increases tire lean when cornering (almost like having more negative camber) as the steering angle is increased.
What happens if you have too much caster?
Caster settings are not a primary, direct factor in
tire wear
. However, excessive positive caster in association with other alignment maladjustments can exacerbate a tire wear issue. For example, a tire wear pattern called feathering can result from a combination of too much caster with incorrect toe settings.

What does bad caster cause?
Negative caster results
in lighter and easier steering but reduced stability when driving in a straight line
. Vehicles with negative caster do not handle as well. A symptom of negative caster is a sloppy or loose-feeling steering wheel (which is lot less common than a hard to turn wheel).
What happens if caster is off?
It is no different on four wheel vehicles. If you don’t have enough positive caster (forks too little angle toward the front) the
car will wander and feel unstable
. … So the vehicle would pull to the side with the “fork” further back. Again, caster, like camber can cause pulls, but caster will rarely cause much wear.
What is the first step in performing a four wheel alignment after the wheel units are installed?
The adjustment procedure for wheel alignment is as follows:

caster doesn’t affect tire wear like camber
, it does have a big impact on steering and handling.
What do I adjust first camber or toe?
We learned that every time you adjust the toe (without turn plates), you must push the car backward and then forward roughly 10 feet. This loads the front tires to produce the most accurate readings. Toe is always set last because adjusting
camber
or caster moves the control arms, and that changes the toe.
