Besides the frame rails what else are some good jacking spots

Everyone I know uses the pinch welds. I held off for the longest time but now I sometimes use them as well. The other place I see used is the diff. I'm not sure if any of these are good places, i'm just saying thats what people do.

I'd like to hear if anyone has had any problems using these spots.

yeah i was looking at the manual it was saying middle of the axel i just dont know where
