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 Ranger XP 570 Working\u003c\/h2\u003e\n\u003cp\u003eBefore ordering, decide whether you are replacing a single failure or refreshing all four corners — the set of four covers a complete front end and is the usual choice on a machine of this age. 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 Polaris services them. 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 Ranger XP 570 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.
