The ball joints are part of the lower control arm . The control arm is not extremely difficult, but not easy either. First remove the nut on balljoint, then pull the ball joint out of the knuckle, that may take a pry bar, remove front control arm nut and bolt, and two bolts on rear of control arm bushing, reverse process to install. The Ford workshop manual says to replace the control arm nuts and bolts, but I hardly ever do. Have never had a problem. Torque front bolt to 111 lb-ft, and rear to 73 lb-ft. Hope that is good for you.

i would replace the whole control arm because the bushing are probably worn out too and it's easier than pressing out the ball joints. make sure you have a spring compressor tool when you do this or you could get seriously injured

SPECIAL SERVICE TOOL(S) REQUIRED
Ball Joint Remover
Remove the front wheel spindle (3105) and ball joint assembly from the axle. Refer to Wheel Spindle, F-150, F-250, F-350 in the Removal and Installation portion of this section.
NOTE: Lower ball joint must be removed first.
Install the front wheel spindle in a vise and remove the snap ring from the lower ball joint.
Remove the lower ball joint from the front wheel spindle using U-Joint Tool T74P-4635-C and Receiver Cup D81T-3010-A5 or equivalent for F-150. Use Ball Joint Remover T94T-3010-AH for F-250 and F-350.

CAUTION: Do not heat the ball joint or the front wheel spindle to aid in removal.
Assemble U-joint tool and cup on the upper ball joint, and turn forcing screw clockwise until ball joint is removed from the front wheel spindle.
CAUTION: Do not heat the ball joint or axle to aid in installation. NOTE: Upper ball joint must be installed into the front wheel spindle first.
NOTE: Individual ball joint tools are included in Ball Joint Adapter Set D81T-3010-A or equivalent.
To install the upper ball joint, assemble C-frame assembly, Ball Joint Receiver Cup D81T-3010-A5 and Installation Cup D81T-3010-A1 and D81T-3010-A3 or equivalents inside cup D81T-3010-A4 or equivalent in position on the front wheel spindle.

To perform the following procedure, the lower control arm must be removed from the vehicle. Refer to Removal And Installation for that procedure.
Using a screw driver or other suitable tool, pry the seal boot off of the ball joint assembly
Position receiving cup, Special Tool 6758 to support lower control arm when removing ball joint assembly. Install Remover, Special Tool 6919 on the top of the ball joint assembly.
Using the arbor press, press the ball joint assembly completely out of the lower control arm.
NOTE: When installing ball joint in lower control arm, position the ball joint in control arm so notch in ball joint stud is in the direction shown. This will ease assembly of the ball joint to the steering when installing pinch bolt.
By hand, position ball joint into ball joint bore of lower control arm. Be sure ball joint is not cocked in the bore of the control arm, this will cause the ball joint to bind when being pressed into control arm.
Position control arm with installed ball joint, in an arbor press with Receiving Cup, Special Tool 6758 supporting the lower control arm. Then center Installer, Special Tool 6908-4 on the bottom of the ball joint
Carefully align all pieces. Then press the ball joint into the lower control arm until it is completely seated against surface of lower control arm. The ball joint is correctly installed when there is no gap between the ball joint and the lower control arm. Do not apply excessive force against the ball joint or the lower control arm.
Install a NEW seal boot by hand as far as possible on the ball joint. Installation of the seal boot is to be with the shield positioned as shown.
CAUTION: Do not use an arbor press to install the sealing boot on the ball joint. Damage to the sealing boot will occur if excessive pressure is applied to the sealing boot when it is being installed.
Place Installer, Special Tool 6758 over seal boot and squarely align it with bottom edge of seal boot. Apply hand pressure to Special Tool 6758 until seal boot is pressed squarely against top surface of lower control arm.
CAUTION: A replacement ball joint is not pre-lubricated. Properly lubricate the replacement ball joint using Mopar Multi-Mile grease or an equivalent. Lubricate ball joint after seal boot is installed but prior to top of seal boot being pushed down below notch in ball joint stud. Air must vent out of the seal boot at notch when grease is pumped into ball joint, failure to do so will balloon and damage seal boot. Do not over grease the ball joint, this will prevent the seal boot from pushing down on the stud of the ball joint.
CAUTION: After the ball joint is properly greased, clip the end of the grease fleeing off below the hex. The ball joint seal boot is non-purgeable and further greasing is not required and can result in damage to the seal boot.
