Works on Tie Rods With Inaccessible Flats. Includes an Additional 1 1/2" Crows Foot for Chevrolet Colorado and GMC Canyon. Many inner tie rod end sockets do not have a complete hex on the full length of the socket. The rounded socket ends prevent access to the wrench flats. This tool utilizes six crows feet, to engage the wrench flats. Long socket slips over tie rod end and connects to the crows foot. The inner tie rod can be removed and installed without removing the rack.
