Had the timing belt/water pump/etc changed on 12/04/2016 at the dealership as a preventative step to ensure long life of my '04 Tacoma. Last week while driving the truck gave up the ghost and died on me. The bolt holding the harmonic balancer on was nowhere to be found and the harmonic balancer had fallen off after smoking the crank and key. Dealer wants to simply put a new crank and bearings in it as a fix :/. Consensus is that dealer tech did not torque down the harmonic balancer bolt properly
