For the life of me I cannot find the torque spec for this nut! I've checked the fsm, rsu, rax, final drive, body, etc.. Maybe I'm blind.

53 ft-lbs.

The radius rod installation section (RSU-13) refers to RSU-7 for tightening torque, which is the diagram for all of the components.

Thanks, this is for a sedan though. I should have specified. It isn't listed, oddly.

What year of sedan do you have, I just checked the FSM for a 2005 and it's listed, same pic as above.

2004 6mt

Yep it's listed in RSU-7

Sorry about that. I didn't notice this was for a sedan. As Cleric pointed out though it's still listed in RSU-7.
