I just got one of these blue torque multipliers off Ebay two days ago. Previously I broke a 3/4 on ratchet, a 3/4" breaker bar, and could not turn the lugs with a 1" breaker bar a 4way lug wrench and 5' cheater. the applied force would be in excess of 1400 ft lbs. I took this blue thing and it's 60 to 1 ratio and had 3 sets of duals and a front off in less than an hour. I have 1 set of duals that is spinning the studs with the torque multiplier. It appears I am going to have to tack weld the studs and then try. This thing really works though. Inner and outer wheels.
