I have taken my original torque specifications spreadsheet and modified it to multiple tabs instead of one giant sheet. I have also updated a fair amount of information based on documentation from another forum member. Things highlighted in yellow are either additions or changes. I have also added a date to each subsection so things can be updated easier. I have included the original spreadsheet as the last tab minus the sections that were updated.

I am sure there will be many more changes to come since I noticed several discrepancies and a lack of standards between groups in how their information is provided to whomever manages the torque specifications section of the TechAuthority. I do not have access to TechAuthority but I am willing to work with someone that does to produce a better spreadsheet.

You are awesome - THANK YOU!

As I was searching for torque specs ahead of my planned Rock Krawler LCA install I discovered this oddity:

140 N-m = 103 ft-lbs, but the difference in the degrees doesn't make any sense. dapipp, I noticed in your latest spreadsheet that you have:

Which I'm assuming is correcting the original errors. Can you share where the updated 145 degrees for the LCA nuts came from? Is that the same source as the "do not reuse" direction?

The updated specs came from TechAuthority. I chose to use the "+" symbol rather than write the word "plus", takes up less room.

I would not trust the torque requirements from a Mopar document published in 2018.
Shot in the dark here - 103 plus another 145 degree turn may equal 190.

Torque is a proxy for tension. My understanding is the torque plus angle is more reliable to get the proper tension on the bolt. But we're not talking rocket science with tight tolerances here so I guess they decided to make the Mopar lift ones easier for the installer by listing the closest total torque value.

What did you end up torqueing you Rock Krawler LCA's to? I went with 190ft-lbs myself which was a pain so I'm wondering if I needed to torque them that much or if I over did it.

Not knowledgeable with pounds plus degrees. My question is how could you verify something is torqued properly? Let’s say the spec is 44 ft lbs plus 135 degrees. How could I verify that bolt is torqued properly?
TIA

You would have to loosen the bolt, torque to 44 ft lbs, then use a long ratchet, or breaker bar to rotate the bolt 135 degrees. It's a PITA but if that's what the spec calls for it's the best way to replicate the specific torque value.

Thanks man. Was hoping there would be some magical conversion to ft lbs :)

It seems the Front Lower Control arm section has a typo. I assume it should read:

Lower control arm front nut | 140 + 145° | 103 +145° | - |
