I am going to remove the rear axel lift blocks on my 2013 Sierra today can anyone confirm the torque specs?

I am going to remove the lift blocks and I have seen torque specs of 70, 75 and 80. Can anyone confirm what the real spec is? I will try to post pics from the project.

Well, got the U bolts off with no problem. But first time using this HF breaker bar to take off the wheels and it snapped. Off to get another.

I am having the hardest time figuring how to get the top shackle bolt out to put in my lowering shackles. This is driving me crazy.

You have two option usually, 3 technically.

 

Loosen all the bed bolts so that it can move, that way when you put a jack under the rear axle to raise the leaf spring up, it can also push the bed up at the same time and you can sneak the bolt out between the bed and frame. You could also fold the seam of the bed over to give you more room doing the same thing. Unbolting the bed is easier in my opinion.

 

Other option is to remove the leaf spring itself but that job sucks to do on the garage floor.

Thanks for the reply. I wound up not connecting the U bolts so I had lateral movement. It was a serious pain. I will post a video of it when I do one.

Including lunch and a trip to Harbor Freight, it took me 5 hours to do the first side. Took a little less than an hour to do the other.
Lowered three inches. This is the lowering shackles I bought. Wish I saw they came with U bold spacers when I removed the block. Had to do it again on the first side.

I bought an impact last week and I am so so glad I had it. That would have taken exponentially longer without.
The biggest hassle was just figuring how to reach the bolts and get the axle in place. So the second side went easy peasy.

Having the leaf springs lose from the axle was the key for the upper shackle bolt.
