It depends on the year, and whether it's 2WD or 4WD. I suggest entering your question again with the year. People have posted answers for specific year models. All Ford Rangers from 1993 to 1997 have "I-beam" front suspensions as opposed to the upper and lower control arms that most vehicles have. There is a detailed answer for replacing the upper and lower ball joints for '93 through '97 Ford Ranger ball joints at the question: "How do you change ball joints on 199X Ford Rangers?"
replace lower ball joint on ford ranger 2001
how do i change a lower ball joint on a 1992 ranger 2wd
For the lower ones you need a ball joint press from Autozone. They have those on their loan-a-tool. The upper one's come on an arm and you just replace the arms.

u can't just change the upper ball joint, u have to change the whole upper control arm. It is welded to the arm in one piece.
The ball joints can be replaced by removing the wheel. Remove the rotor and brakes. Pound the old ball joint out. Insert the new ball joint with a ball joint compressor.
You need to remove the spindle and press out the ball joints & press in new ones
I believe you can change just the ball joint on the lower control arms , the upper ball joints come with a new control arm
1998 2wd What year? 2WD or 4WD? 2WD 1996
Depends on whether you have coil springs or torsion bars.
Control arm and ball joint are all one unit.
