its really not THAT hard if you have all the tools. you take the front passenger tire off to get to the crank pulley. the hardest part is probably getting the crank pulley nut loose without turning the crankshaft itself. some people clamp down the torque converter, some people use an impact wrench on it. you'll also need a "harmonic balancer puller" which is free to borrow from autozone and maybe other auto parts stores too
