I made a tool to press in lower balljoints into the spindle, using a section of 2" sch.80 steel pipe. Seems to have worked well but I'm not 100% certain I have fully seated the ball joint. The flange on the joint that shoulders down onto the spindle looks almost flush with the spindle on the near side but is raised slightly on the farside recessed back in the inaccessible area. But, if I measure the bottom side where the joint protrudes through the spindle I get a uniform protrusion of about 0.050" all the way around which makes me think the joint is in straight and flat but perhaps the recess where the joint flange fits into on the top side is not of uniform depth and so it appears not uniformly seated when viewed from the top
What do you think, is it seated all the way?
