Every task has a specific tool needed for a safe and successful completion. Dismantling and rebuilding yourFits Ford 9 Inch rear-end is a daunting task - it requires some heavy lifting and incredible strength to assemble one. We have just the tool to help you rebuild your rear-end. This adjustable pinion yoke wrench is used to hold the center gear section of your rear-end in place, while you unscrew the pinion nut. This tool bolts to your pinion yoke (adjustable, fits various different yoke styles) and prevents it from spinning in place when removing or installing the pinion nut. Keep your project moving forward - with the right specialty tools from Speedway Motors!
