180 does have me concerned, but maybe that's only because the radiator boiled over and sprayed antifreeze in my face (through the cranked out windshield) less than an hour after I'd bought the truck. Is there any reason not to switch between a 160 and a 180 with the weather?

I've tried lots of penetrating oil and some light hammering, to no effect. Maybe I just need to give it more of a whack? The other side came off with zero effort. All I had to do was take the wheel off and pull. I like things that are that easy

I don't need instructions. I have a hammer.
