sensor 2 should be behind (after) the converter.

yep. sensor 2 is post cat. sensor 1 is before cat.
how many sensors does your truck have ? 3? hmm. i thought it was either 2 or 4.

Not sure which parts store told me that, but said I had 2 up & 1 down. They were pretty sure it was the back one, but would not guarantee it. I believe the rear sensor cost more as well.

Are you sure you have three sensors? Usually you would have two or four.

Okay, I went under to change the ABS speed thingy to try & fixmy 'ABS/brake' trouble light issue. Problems there that will need its own post.

Anyway, my Dodge has 2 O2 sensors, one up and one down. From the looks of it, I'm thinking WD-40 to loosen it up?

wd-40 works but the best product for lossening bolts (or O2 sencsors in this case) is PB Blaster. every garage should have a can.
