• [Forged alloy construction with controlled failure point]: The tool body is die-forged from chromium-molybdenum alloy, featuring a specifically engineered material thickness at the fork neck. This creates a predetermined structural failure point—if excessive force is applied, the tool itself will bend or break first, thereby protecting more expensive vehicle components like the steering knuckle.
• [Progressive Scissor Action, Multi-Pivot Lever]: Unlike simple fork tools, it employs a dual-pivot scissor mechanism. The primary pivot provides wide opening and coarse positioning, while the secondary fine-adjustment pivot near the force screw precisely transmits concentrated high-pressure force onto the ball stud. This achieves clean separation without impact loads on surrounding components.
• [Black Oxide Coating, Infused with Dry Film Lubricant]: The black oxide finish serves more than corrosion protection. It incorporates dry film lubricants like molybdenum disulfide to reduce friction on the force screw threads during high-torque application, preventing wear and ensuring smooth operation even under extreme pressure without continuous wet lubrication.
• [Two-stage removable pin system ensures precise jaw alignment]: Equipped with two sets of hardened removable pins, the jaws lock into wide or narrow spacing. This allows users to perfectly parallel-align the jaws with the ball stud before final tightening, eliminating cantilever clamping forces that could cause pin shearing and ensuring separation forces are applied axially.
• [Critical preload verification and pin protection protocol]: Before applying force, visually confirm the tool's jaws are flush against the machined shoulder of the knuckle or control arm, not pressed against rubber dust boots or ball joint housings. Fifteen minutes prior to operation, spray penetrating lubricant onto the ball joint pin threads to prevent thread seizure during separation.
