The design has barely changed because it does not need to: thread the housing in like a nut and bolt, use a chromoly stud, and make the whole assembly serviceable so a worn joint gets rebuilt rather than binned.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eKeep Your Mule Pro Front End Working\u003c\/h2\u003e\n\u003cp\u003eBefore ordering, confirm your Mule Pro variant and year, and note that this listing covers the upper A-arms only — two joints does one axle's worth of uppers. If the boots are torn but the joints are sound, the Keller boot replacement kit is the cheaper fix. If the joints are worn but the housings are good, the Keller rebuild kit for Kawasaki services them. On a working machine, tie rods and A-arm bushings are worth inspecting while everything is apart.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eInstallation Video\u003c\/h2\u003e\n\u003cp\u003eOfficial SuperATV installation walkthrough with Todd Keller: \u003ca href=\"https:\/\/www.youtube.com\/watch?v=Mbt4iX4DWRA\" target=\"_blank\" rel=\"noopener\"\u003eHow To Install Keller Ball Joints\u003c\/a\u003e\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Why do Mule Pro ball joints pull out of the A-arm?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The factory joint is retained by a snap ring seated in a groove.
