If so, non-knurled ball joints are what you are looking for. Ball Joints are typically offered in two fitment styles, knurled and non-knurled. Synergy MFG has been making HD knurled ball joints for years intended as replacements for those looking for better ball joints after going through several sets of OEM style ball joints that simply don't hold up to the rigors of off-road use and large tires. Knurled ball joints allow the ball joints to still fit tight in the knuckle \"C\" bores after the bores have been enlarged from several sets of ball joints being pressed in and out. Knurled ball joints are a \"fix\" after non-knurled ball joints are no longer a sufficient press-fit.\u003c\/p\u003e\n\u003cp\u003eSynergy MFG's new Non-Knurled HD Ball Joints are ball joints intended to be used in NEW front axle housings or replacing stock, non-knurled type ball joints. If your axle housing already has had knurled ball joints installed or you are on your umpteenth set of ball joints, these are not for you. Look into Synergy MFG's Knurled HD Ball Joints instead.\u003c\/p\u003e\n\u003cp\u003eBenefits:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSignificantly increased durability over stock style ball joints\u003c\/li\u003e\n\u003cli\u003eReplacing worn ball joints can correct steering, alignment issues, and even death wobble\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFeatures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSold in sets of 2 or 4 to replace a single side or both sides of the vehicle.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty, greasable, metal on metal design for significantly increased wear resistance and prolonged life\u003c\/li\u003e\n\u003cli\u003eBall Joint bearing surface area is considerably larger than stock due to elimination of the stock style inner nylon liner\u003c\/li\u003e\n\u003cli\u003eBall joint housing is manufactured from sintered graphite, bronze, and 1045 steel for a strong, smooth, bearing surface\u003c\/li\u003e\n\u003cli\u003eBall joint stud is manufactured from induction heat treated 4140 steel for maximum strength and smooth operation\u003c\/li\u003e\n\u003cli\u003eBall joint dust boot is made from wear\/tear-resistant black nitro-butile rubber (NBR)\u003c\/li\u003e\n\u003cli\u003e12 Month Unlimited-Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNotes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with all aftermarket axle shafts (including RCV) with no modifications needed\u003c\/li\u003e\n\u003cli\u003eSynergy High-Performance Grease (4119) recommended\u003c\/li\u003e\n\u003cli\u003eMetal on metal ball joints require a small break-in period of typically 100-500 miles to fully \"seat\" the bearing surfaces.

Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press-fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press-fit, knurled ball joints are required.\u003c\/li\u003e\n\u003cli\u003eUse of the improper ball joint style for the axle housing voids our warranty.
