TeraFlex HD ball joints are engineered to handle the increased load caused by oversized tires and offset wheels. The upper ball joint incorporates hard sintered wear bushings to handle extreme side load demands without failure. The lower ball joint features a threaded top cap for adjustable preload and allows grease servicing without axle shaft removal, even with larger RCV shafts. A machined grease passage in the lower joint housing assembly provides lubrication access without affecting the ball joint load surface.

Note:
Note: Fits 2007-2012 JK Wrangler Dana 30 andamp; Dana 44 axles. We recommend ball joints without knurls as they will not score the inner knuckle and open up the bore. We also offer ball joint with knurls for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed in the past
SOME 2012 and ALL newer Jeep Wranglers come factory with larger front axle shafts Dana 30 and 44 than previous years, and will require grinding on the stub shaft forging parting line for clearance.
