Jeep JK Front Upper Control Arm Torque Specs
The front upper control arms (UCAs) stabilize the axle and work in tandem with the lower arms to set your caster angle. Note that reaching the passenger side UCA bolt at the frame can be exceptionally difficult due to its tight proximity to the exhaust piping.
