TeraFlex 3442002 HD Ball Joint Kit w/o Knurl; Wrangler JK

Often with larger tires and off-road use, the factory ball joints tend to wear out. This causes steering shimmy, uneven tire wear and in some cases, the dreaded "Death Wobble". As a pioneer in the off-road industry, Teraflex has designed a superior ball joint that is made of 4140 Chromoly Steel that is uniquely designed for optimum performance. These are also heat treated with grease fittings for a simple servicing without the need to pull the entire steering knuckle off!

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
• Factory-style serrated flange nut & grease fitting

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
• Heat treated 4140 chromoly ball/stud
• Huge 30mm (1.18") ball
• Factory style serrated flanged castle nut
• Ball joint pre-load adjustability provides the end user w/ near effortless wear adjustment (kit 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 zerk fittings 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
• Low-profile seal prevents contaminants, while allowing spent grease to evacuate from the ball joint

Install Notes

• Teraflex recommends Ball Joints w/out Knurls (# 3442002 or # 3440000) as they will not score the inner knuckle & open up the bore.
• We also offer Ball Joint w/ Knurls (# 3442022 or # 3440020) 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.
