{"product":{"id":10953186836822,"title":"Apex Chassis KIT102 HD Ball Joint Kit - Jeep Wrangler JK \u0026 Grand Cherokee","body_html":"\u003ch2\u003eSummary\u003c\/h2\u003e\u003cp\u003eThe Apex Chassis HD Ball Joint Kit for the Jeep JK and Grand Cherokee puts tight, confident steering back into a Jeep front axle. On a Wrangler JK (2007-2018) or Grand Cherokee (1999-2004), worn ball joints show up as wander on the motorway, vibration through the wheel and vague response on the trail - and lifted setups with larger tyres wear the factory joints even faster. This kit replaces the front joints with forged steel housings and heat-treated chromoly studs built to carry that load. It is a genuine Apex Chassis part, imported to the UK.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eJeep JK owners chasing out steering wander, vibration or death-wobble contributors\u003c\/li\u003e\n\u003cli\u003eLifted JK builds on larger tyres that load the front joints harder than stock\u003c\/li\u003e\n\u003cli\u003eGrand Cherokee (1999-2004) owners restoring worn front-end feel\u003c\/li\u003e\n\u003cli\u003eTrail and daily Jeeps that need a fit-once fix rather than repeat factory joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Joints Matter On A Solid Axle\u003c\/h2\u003e\u003cp\u003eThe ball joints locate the steering knuckle on the axle, so every input - steering, braking, articulation - passes through them. Once they wear, no amount of tracking adjustment brings back precision. Compared with fitting another set of factory-style joints, this kit's CNC-machined forged housings and polished chromoly studs are built for the loads a modified or hard-driven Jeep actually sees.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Apex Chassis (USA)\u003c\/li\u003e\n\u003cli\u003eProduct Type: HD ball joint kit (front, full vehicle set)\u003c\/li\u003e\n\u003cli\u003eSKU: KIT102\u003c\/li\u003e\n\u003cli\u003eIncluded Items: 2x BJ107 upper, 2x BJ109 lower\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Jeep Grand Cherokee (1999-2004) 2WD or 4WD; Jeep Wrangler JK (2007-2018) 4WD\u003c\/li\u003e\n\u003cli\u003eMaterial: Forged steel housings, chromoly ball studs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eConfirm your model and year against the application list before ordering - fitment shown is manufacturer reference. Ball joint replacement on these axles is a press-in job, so plan the right tooling or a workshop visit, and book an alignment afterwards. If you are curing death wobble, inspect track bar, tie rod ends and steering damper at the same time so one worn part does not mask another.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eApex Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eHD ball joint kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eKIT102\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded Items\u003c\/td\u003e\n\u003ctd\u003e2x BJ107 upper; 2x BJ109 lower\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle Application\u003c\/td\u003e\n\u003ctd\u003eJeep Grand Cherokee 1999-2004 2WD\/4WD; Jeep Wrangler JK 2007-2018 4WD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eForged steel housings, chromoly studs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWill this help with death wobble on my JK?\u003c\/h3\u003e\u003cp\u003eWorn ball joints are a common contributor.
