Q: How to remove and install balljoints on different types of axles on Ford F-250?
A: Use the balljoint removal/installation tool to remove the upper balljoint first, then the lower one. Do not heat the axle. To install, use the tool to seat the lower balljoint first, then the upper one. Install the snap-rings and reinstall the spindle. Remove the spindle/knuckle and lower balljoint snap ring. Use the tool to press out the lower balljoint first, then the upper one, and then install the new upper balljoint, then the lower one along with the lower balljoint snap-ring, and reinstall the spindle/knuckle.
