I'm putting new, front upper control arms on a 1998 Ford Ranger 4x4. Removing the old ones and installing the new ones looks simple enough. I have the torsion bar, front suspension.

I need to know what the torque specifications are for each of the three bolts.

I would like to know what size the two bolt that hold the upper control arms to the the frame mounts are, so I can get new bolts. The arms came with the smaller bolts that go through the spindle, but they didn't include the ones that go through the frame mounts. Anytime I replace something on a vehicle, I always use all new fasteners.

 

As tight as you can with a 3/8 drive. Btw there are no rear uca's :p

 

After performing this procedure, it will be necessary to have the wheel alignment checked and adjusted by a professional shop.
Position the steering wheel to the on-center position. Loosen the wheel lug nuts.
Raise and safely support the vehicle. Position the jack stands under the lower control arms.
Remove the wheel lug nuts and wheel.
Before removing the steering knuckle-to-upper ball joint retaining (pinch) bolt, secure the steering knuckle from tilting.
Remove the steering knuckle-to-upper ball joint retaining (pinch) bolt and separate the two components.
Make alignment marks on the control arm pivot bolt cam assemblies.
To remove the left side control arm proceed as follows:
Remove the nuts and cam bolts from the control arm pivot points.
Pull the control arm from the vehicle frame.
To remove the right side control arm, proceed as follows:
If only the ball joint is to be removed, make alignment marks on the control arm and ball joint assembly then remove the two retaining nuts and the ball joint. Skip to the installation procedures.
Remove the nuts and cam bolts from the control arm pivot points.
Pull the control arm from the vehicle frame.
To install:
For right-side control arm, if removed, install the ball joint assembly and retaining nuts to the control arm and tighten the nuts to 95-128 ft. lbs. (128-173 Nm).
Install the control arm pivot points into the frame pockets.
Install the cam bolts and nuts, align the matchmarks and tighten the nuts to 84-113 ft. lbs. (113-153 Nm).
Connect the upper ball joint shaft to the steering knuckle. Install the retaining (pinch) bolt and tighten to 30-41 ft. lbs. (40-55 Nm).
Install the wheel and snug the lug nuts.
Lower the vehicle and tighten the lug nuts to 100 ft. lbs. (135 Nm).
Have the alignment checked by a professional repair shop.

 

Thanks for the instructions and torque specifications, uh1mtp.

My lower ball joints are also toast. Does anyone have a how-to for changing the lower ball joints; with torque specifications? Any replies are greatly appreciated.

 

Camber should not change. Alignment isnt really neccessary considering there are blocks and not cams in the uca mounts
