Engine pull questions

[JRS]

I have a Chiltons manual for a 96 4 wd 4.3 L vortec engine instructions and not quite sure what the following means, not getting a good picture of what they are saying:

" On 4wd models remove the front drive axle bolts and roll the axle downward "

Where are these located, and why does this need to be done ?

" On 4wd models loosen the front body mount bolts " Why does this need to be done ? particularly if trans is staying in vehicle when engine pulled ?

Thanks

Hello, is anybody there ??

Ok, I will try another forum to see if I have better luck. Hate to say it as I have a long history of GM vehicles in the past, but now have a Ford full size and belong to their forum and have to say it is quite good. I do have other GMs, Cadillacs, Grand Ams and belong to their forums, so far the Ford truck forum is the most responsive ....
