Installing BDS Caster
Adjusting Bolts
after a lift these simple
bolts set the caster back where it belongs
When you lift a Jeep
often the lift alters critical suspension
measurements that can cause the Jeep to wander,
pull, or track strangely down the road.
Most suspension companies offer special
components to go with the lift that return the
Jeep's suspension back to proper alignment to
restore its road manners.
In a JK two main
alignment factors are affected by a lift.
Thrust angle and castor. Read more on the

Installation
With the Jeep
properly supported on stands or a lift remove
the lower control arm bolts only do one at a
time to avoid the axle rotating too much.
With the control
arm out of the way grind open the bolt hole to
create a slot. Most times the bolt will go
toward the rear so if you feel that you will get
it correct this way you can leave the forward
slot alone.
Install the new
BDS bolt and cam washer. The cam washer
will ride alone the raised metal on the axle
mount keeping the adjuster in place. With
the bolt toward the rear the caster angle will
increase. The bolt located toward the
front will decrease the angle. Factory
caster angle is 3.7 to 4.7 degrees.
Repeat the
grinding on the other side. With both
bolts installed align them to achieve the proper
angle and tighten them to the specified torque
ratings. Drive the Jeep for a short
distance and check the bolts to make sure they
haven't moved or become loose.
Periodically check the bolts to be sure they
stay where they belong.
A qualified shop
can check the Jeep for the accurate caster angle
and make minor adjustments to the bolts to get
things within spec. See

Steering Alignment
