Ford F-150/Expedition Uniball Upper Control Arms Part Number 10016

Park the vehicle on a flat, level surface. Make sure the vehicle is in park or in gear, and that the parking brake is set. Raise the front of the vehicle and support the frame with jackstands.

Remove front wheels.

Some aftermarket coilovers may allow enough access to remove the upper control arm bolts without removing the coilovers. If so, the coilovers do not need to be removed.

If necessary, remove the coilover to gain access to the upper control arm bolts. Remove the lower shock bolts and then remove the (3) nuts on top of the coilover (use a 15mm, 27mm & 30mm socket/wrench for stock assembly, aftermarket replacement coilovers typically use a 9/16" and 15/16" socket/wrench).

Removing the lower shock end out of the pocket in the arm can be difficult because you are fighting the bushing stiffness from the lower control arm and sway bar tension. Disconnect the swaybar links and/or the top of the other shock to relieve some of the tension.

Disconnecting the tie rod end can ease removal of the coilover if necessary.

Remove coilover assemblies from both sides of vehicle.

Loosen the taper on the upper ball joint and the tie rod end using a 21mm socket/wrench.

Strike the spindle with a large hammer where the upper ball joint stud engages the spindle. A couple quick strikes should separate the taper. Alternatively, a ball joint separator may be used.

Support the spindle so that it does not over extend the CV joints when detached.

Using a jack, support the lower control arm to prevent the suspension from being at full droop.

With the upper control arm detached from the spindle, begin to loosen the upper control arm from its mounts in the frame using a 21mm socket/wrench.

Remove the stock upper control arms.

Apply grease to the inside of the Load Rings and slide them on to the Pivot Sleeves. They should sit in the center of the Pivot Sleeves.

Apply grease to the inside of the upper control arm pivot tubes and insert the Pivot Sleeves with Load Rings into the arms.

Apply grease to the inside and outside of the Hat Bushings, and slide them into the upper control arm pivot tubes.

Make sure the Hat Bushings are fully seated in the control arms, if they become too tight to push in, check to make sure the Pivot Sleeves are aligned properly. If the bushings are still too tight of a fit, use a large pair of pliers or a vice to fully seat the bushings, being very careful not to tear them.

Thread the zerk fittings into the arms. Do not overtighten!

Install the taper adapter up from the bottom into the uniball. The tapered pin should point down, towards the spindle.

Place the domed top cap on top of the uniball and hand thread in a 12 point 1/2-20 cap screw.

Install the Grimm OffRoad Upper Control Arms onto the vehicle. Note the orientation of the arms, the uniball should be closer to the rear of the vehicle.

Re-install the factory upper control arm hardware, keeping hardware hand tight for now.

Re-install coilovers if they were removed.

Pivot the tapered stem so that it lines up with the tapered hole in the spindle. Push the upper control arm downward so the tapered pin engages the spindle.

Take care when inserting tapered pin into the spindle to not damage the threads.

Use a 21mm socket/wrench to fasten the supplied nylock nut onto the tapered pin to get it to seat properly.

Do not use an impact wrench for this step!

If the pin spins, you may use the upper 12 point cap screw to prevent it from spinning.

Torque the nylock nut to 100 lb-ft [135 N-m].

Grease the zerk fittings until grease is visibly coming out of the bushings and then tighten the pivot bolt using a 21mm socket/wrench.

Torque pivot bolt to 111 lb-ft [150 Nm].

Re-install wheels and put vehicle back on the ground.

Torque lug nuts to factory spec.

Remove the 1/2-20 12 point cap screws from the top of the uniballs. Apply provided threadlocker to the threads, and re-install.

Torque 12 point cap screws to 90 lb-ft [122 N-m]

Verify all hardware has been torqued.

Have vehicle professionally aligned.

If the 10019 Billet Upper Control Arm Cap Set was purchased, they can be installed now.

Re-check all bolt torques after the first 100 miles, and after every trip offroad.

Uniballs benefit from basic maintenance. Keep them clean and use a Teflon based dry lube to maximize their service life.

Grease the control arm bushings periodically, especially after wet or dusty trips.

When regreasing the upper control arm bushings the upper control arm bolt must first be loosened. After regreasing and purging the old grease, the upper control arm bolt can be retorqued.
