I really appreciate the response. I guess I was confused about torque angle vs torque angle yield. The individual bolts don't have a warning on reuse but the part number for the LCA nuts does.
Regarding the purpose of the moog grease fittings on their bolts .. Guessing to reduce possibility of corrosion locking the cams or seizing to the bushing inserts.
The top speed is software limited, I don't think there's a way to change it without de-doing the whole truck. If you can get a CAN log per my above post we can try seeing if there's anything obvious going on. What happens when you plug the truck in to charge it, does it ever fully charge up or does it stay at low battery %?
The LCA bolts are NOT a one time use fastener. GM does not have them called out as such at all.
They are torque plus degree, but not a one time use TTY. Nowhere in the service manual does it call out for replacing the LCA bolts for being one time use. The factory spec would apply to the Moog bolts as well.
I see two things different. The Moog bolts are greaseable (which I see no point in) and they don't have one of the washers welded to the bolt like the factory bolts, so they can be used in all 4 positions.
Think about it. The LCA bolts are now the alignment adjustment point, instead of the UCA bolts like the prior generation. A bolt that is meant to be adjusted for alignment...would it make sense to make it a one time use component? How would you get an alignment done in the first place? You couldn't.
Also. What TSB exactly? There is no TSB that I see for 2019-2026 for over-torquing LCA bolts. There was a PI, PIT5533C, but that covered 2014-2018 body trucks for re-torquing LCA mounting bolts. But those trucks to a 2019-2026? Not the same, so PIT5533C does not apply.
