1. Position the control arm (4) into the frame brackets. Install bolts (1) and nuts (2). Tighten to 176 Nm (130 ft. Lbs.).
2. Reposition the wheel speed wire (5) into the retaining brackets (3).
3. Insert ball joint (6) in steering knuckle (7) and tighten ball joint nut to 95 Nm (70 ft. Lbs.).
4. Install the wheel and tire assembly.
5. Remove the support and lower vehicle.
6. Perform a wheel alignment.

Since you are replacing the arm, the caster or camber may have changed from the new component being replaced. The tie rods only do toe in not caster camber.

It does not list sizes of wrenches for the job.

As I remember, 15/16 is one for the attaching bolts to the frame and 3/4 or 7/8 for the ball joint nut.

No special tools required.

The arm only goes on one way only.

The best you can do is eye it up. Otherwise you need gauges to check the camber.

Roy

Camber is how the tire contacts the ground. The tire should sit flat on the ground and not tilt in or out.

Gauges are part of alignment equipment.
