I have used the expensive tool and this tool is better since it comes with all three of the bearing halves with sleeves ( the expensive tool charges for the extra halves and sleeve ). + it workes on many more carrier bearings that what the description. Ive removed bearings from series 1, 2, 3, land rovers. Gm 10 12 bolts its just a great tool to own if you do one a year or everyday like myself. No problems just kèp it greased.
