Suspension replacement question

[Zibodo]

I am in the process of replacing any component in my suspension that has rubber in it as well as shocks. I Just want it to drive smooth.

In order to get access to the shocks for removal, I needed to remove the axle from the output flange of the transmission by removing the 6 8mm hex bolts. They came out OK, but now on installation, I am wondering if I need to add locktite to the threads as the specified torque seems low (29 in-lb or 39 N-m per Bentley) compared to how hard they came off. Any thoughts? Of course they are in and torqued so I would have to go backwards to do it.

Also can I reuse nuts on suspension components with locktite or do I just need to replace them as specified?

PS Let me just say it was harder than expected since everything was frozen.
