I did a search for this and came up with very little to answer my question.
searched "rear u-joint replacement"

so here goes, I need to replace the u-joints on the 96 4x4 blazer (Rear shaft).

I do not see the snap rings that I am used to seeing.

I see the white pins ??

I see a post here that said heat them up.

Can I uses a propane to get it hot enough to get the caps out of the yoke ??

 

Well I tried it and it did work , just took a bit a time. All is good
