thanks for getting back scottydoggs. now that I have it apart, I understand how the tool works. The tool I rented fits perfectly on replacement tie rod, but it is different from one you posted, it has interchangable "half-sockets" that fit over entire ball joint and flats behind joint--the socket isnt deep enough and flats on socket are too thick, where the one in your pic has thin interchangable pieces that fit only flats...

the oreily's near me rents same oEM 27185 tool i have, but sells a lisle tool sim to what you posted for $100. sad....
