Teraflex 1353000 Heavy Duty Ball Joint Set with Knurling for 84-06 Jeep Cherokee XJ, Comanche MJ, Grand Cherokee ZJ, Wrangler YJ & Wrangler TJ

TeraFlex Heavy Duty 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 with out failure and includes an easy top access grease port for simple maintenance. The lower ball joint features adjustable preload using the included tool when assembled as well as future adjustments. The advanced grease system allows grease servicing to be performed without axle shaft removal. Dual machined grease passages in the lower joint housing assembly provides lubrication access without affecting the ball joint load surface. The lower ball joint also eliminates the nylon ball socket wear sleeve that is prone to failure.

These ball joints with knurls (1355300) are for ball joints with 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. We recommend ball joints without knurls (1355100) as they will not score the inner knuckle and open up the bore.
