Ball Joints
Browse allProduct Details
Important Notes:
- These ball joints with knurls 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.
- Teraflex recommends ball joints without knurls (# TF-1353100) as they will not score the inner knuckle and open up the bore.
Fits:
- 1997-2006 Jeep Wrangler TJ
- 2004-2006 Jeep Wrangler TJ Unlimted
Description:
TeraFlex JK HD Ball Joints replace the weak factory ball joints that are unable to handle the demands of repeated off road use or larger tires. Ball joints without knurls will not score the inner knuckle and open up the bore. The upper ball joint has two sintered metal bearings to handle the rotational load and the lower ball stud rides in a metal cup that is threaded to provide for a precise pre-load. In-between the lower ball joint threaded cup and ball stud is a special plate spring made from high carbon tool steel for excellent wear resistance as the lower joint must bear the vehicle weight. The lower ball joint also features an oversized flanged nut for a good bearing surface against the outer knuckle. Both ball joints have grease zerks that are easy to service. The lower ball joint has a special flush needle zerk that is offset for u-joint clearance and ease of maintenance.
Upper Ball Joint Features:
- Extremely hard sintered wear bushings to handle extreme side load demands w/out failure
- Magnesium Phosphate coating to inhibit corrosion throughout
- Heat treated 4140 chromoly ball/stud & 1045 carbon steel housing

Lower Ball Joint Features:
- Hard alloy tool steel slotted wear plate for ball/stud to socket wear protection
- Wear plate features grease channels for increased flow through entire joint ensuring longevity & predictable operation
- Magnesium Phosphate coating to inhibit corrosion & friction throughout

- Ball joint pre-load adjustability provides the end user w/ near effortless wear adjustment (kid includes Preload Adjustment Tool)
- Low-profile single lip dust seal eliminates torn conventional dust boot concerns
- Adjustable ball stud retaining ring for accurate initial & future preload adjustments that can be done w/out any axle disassembly
- Adjustable preload can be performed w/ simple hand tools
- Adjustable end cap w/ two (2) zerk fittings (“Frog Eye”) allow greasing access from either side w/out axle shaft removal even w/ larger RCV shafts
- Dual helical grease grooves machined in the retaining ring allow spent grease to exit through the low-profile seal
