I was wondering if anybody else out there has ever done or thought of switching out the a arms and 4 wheel drive axles off an s-10 blazer and replacing them with the ones off a 1500.
The blazer already has a 700 r4 tranny so im assuming that the axles from the 1500 will fit into the transfer case but i would appreciate any help or suggestions.

 

Axles and transfer cases don't fit together... The driveshaft does that part for you.

With that said, the suspension on the fullsize trucks is physically larger (wider, longer, etc) than the s-series stuff. This would require the removal of stock mounting points for the front axle and the upper/lower a-arms. It would be far easier to do a solid axle swap.
