02 Sensor

What is the trick to changing the front two oxygen sensors in a 01 dakota with a 3.9? I found where they are but seem extremely hard to get to.

First get an O2 sensor socket and a universal joint adapter for your socket wrench, you may or may not need an extender for it. Also get a really good rust eater spray, you'll need to let it set in for a while. Another heat up the pipe with a map gas torch, like propane but way hotter.
