Doing an add-a-leaf. Can you leave the front leaf spring bolts in?

So in order save time, busted knuckles and sore shoulders I was wondering can you do the add a leaf with the front spring bolt left in?

Yup you sure can. I have just unbolted the U bolts and dropped the axle down far enough to get them in.
Make sure you put a C clamp on both sides of the centering pin before you take the pack apart.
Happy wrenching, and consider yourself lucky you don't have to mess with the weld nuts.

Yes, you can do it without removing the main leaf on either end

Ended up getting them to come loose with help from a friend that is built like a brick $h!t house.
