'96 GTX that sat for years in a garage. Got some great help on this forum yesterday in tracking down why our ski won't pull a tube. Crawled under it this afternoon and found the wear ring is missing significant chunks (impeller looks great), so it's time to at least replace the ring and do a pump oil change. While I'm in that far, is there anything else I should do? Is a anti-rattle kit worth it? I haven't read up on the ring process yet, but will before I order.
