Thanks for these directions - I'm pretty sure my sensor has been failing for a year or two and I now that I just bought a house, I finally have a garage I can do the things I've been putting off - like this repair!

Quick question - I have hand tools, jack and jackstands, but no air tools or torque wrench. Do I need the wrench for this or is it not a big deal to get these bolts tightened exactly?
