Harbor Freight sell a 3/4 inch torque wrench for 80 bucks with a lifetime warranty. It is advertized 0-300 lbs but since it is a spring tension device, it isn't hard to set it to 350.
The biggest complaint folks have regarding these torque wrenches is they think it is broken because it won't click in the reverse direction. If they would read the instructions, it says to flip the center section 180 and then it works in reverse. It take about 30 seconds to do the flip after loosening 2 screws.
This tools makes doing the axles a simple and easy task.
