Four stars just because the dust boots are almost impossible to fit onto the ball joint. A metal wire runs along the outer edge of the boot, which does not allow it to stretch enough to fit over the ankle. Otherwise a good replacement. I've read that some people were worried it might pop out as Miats were designed to replace the entire control arm, not just the ball joint, but it came with a snap ring that you put on the underside to keep it does not fall out. The overhead oiler is also a plus over the original parts.
