The upper ball joints are replaceable without replacing the control arms. Use Moog K80008 ball joints and a ball joint press.

The ball joints are a part of the upper control arm. So you have to replace the upper control arms.

    Hello, I am just wandering why you said my explanation was not helpful when it was step by step instructions on how to change your ball joints? I do not understand?

  • Tim Shaner Dec 20, 2014

    The question was on a 2002 model year. You explained for a 2006 - different.

SOURCE: front upper ball joint replacement

The dealer's answer (if you are interested).......

The ball joint is pressed into the upper control arm and has a tapered stud for attachment to the steering knuckle. The ball joint stud is attached and locked into the steering knuckle using a special nut. The ball joint is a sealed-for-life type and requires no maintenance. If the ball joint is defective it will require replacement of the entire upper control arm.

Sorry.

SOURCE: upper & lower Ford Ranger ball joints replacement

Approx.$250 in parts & rest is labor. Probably 3 to 4 hrs labor at most, even at 5 hrs labor, that's $100/hr labor. It must include alignment after the repairs, correct? Not sure what your going rate for labor is in your area. Probably wouldn't hurt to call around for a second opinion& estimate just to be sure.

SOURCE: how do i remove an upper ball joint from a 2004

The ball joint on your vehicle is not replacable by itself. The control arm which holds the ball joint must be replaced. The nuts holding the arms on will have a small metal tab. That tab holds the arm in allignment. Note the location of the tab before removing. These must go back in the same way they came out. Also check the new arms for correct sides. There will be a "R" and "L" on them. They can be confused and will fit. Good luck then get an alignment to check.

Here's a YouTube video showing the procedure on the passenger side. Apparently, you can't get just the upper ball joint, you have to replace the upper control arm, but it looks to be a fairly easy project. You can skip the first three minutes of the video - the work starts at about 3:15.

Need to replace upper and lower ball joints on a 1999 Ford Exploe


This job is essentially man against beast with hammer style of job. You will need an alignment after you are finished, seriously easier and safer to let a shop do this.

If you do it yourself be advised of the HUGE potential energy stored in the spring, and do not allow it to release....
