    Very easy to replace, just go under your truck, locate the o2 sensor, and the o2 sensor is basically a bolt, just unplug the o2 sensor harness, and then unbolt it from your exhaust pipe. What i suggest is to just shop around, get quotes from different places to get a good price, everywhere is different.

    ok, cool.
    the engine light came on a while back and I cleared it but the fault never came back on... is this normal ?

    It may have to go thru several cycles before it comes back on, sometimes it will take several hundred miles before it comes on again.
