well, having a convenient, secure, covered area, or garage for car work is an advantage. Your car may or may not have to pull the crank nut. I'm not sure I know anyone w/ a 400 ft-lb torque wrench. When I _did_ have to pull the nut to replace the front crank seal, I marked the nut's position, and tightened it until the marks lined up again, figuring that was close enough. Had to use a length of pipe something like 4 ft. long over my large 1/2" breaker bar to get the leverage to break it free and re-tighten. A torque wrench w/ that capacity is on of those tools-you-hope-you-can-borrow-because-you-made-your-mechanic-your-best-friend. I would ask for a gas allowance or reimbursement or see if there's anything they're willing to do, considering gas prices lately. It never hurts to ask, as long as you ask politely.
