All above comments and advice seem accurate. But the description of "very, VERY tight" is an understatement. I use a 18" breaker bar with a hex socket to break the torque during removal. But if you think that removal is hard, installation is even worse. I think the spec calls for 40nm which doesn't sound too bad but most torque wrenches aren't long enough to give you good leverage and every time I do this I swear something bad is going to give when the wrench finally clicks. IME if you don't torque the sucker down it'll make all sorts of noises. You can do this alone, but its easier with 2.
