Torsion bars

CRUZE 418 said

I am a little guilty of all of the above. Could not see a way of torquing it here on the ground, couldn't swing a torque wrench. Plus I had to test drive it enough to get the bugs out for the drive to the alignment shop. They torqued the lca's. Did not loosen and then torque. So, I am back to square one. Either I have ruined the bushings or not. Will try loosening and retorque first, which means going back to the alignment shop. It's always something.
The bushings are pressed into the k-member? Will take a look at the FSM. At least I think I know what I am looking for now. Month of July is pretty much shot for me, so may be awhile before I have answers.
Will post when I get things sorted out.
Thank you all for hopefully pointing me in the right direction!.

The bushings are pressed into the LCA. If the LCA pivot nuts were torqued with the suspension hanging you've probably torn the rubber bushings. Nothing in the rubber LCA bushing/LCA pivot pin assembly spins, so, all of the travel in the suspension has to come from flex in those rubber bushings. So the pivot nuts have to be torqued at ride height so half the travel is flex one way and the other half is flex in the opposite direction. If they're torqued with the control arms on the bump stops, all the travel is in the same direction and that's more travel than the rubber can flex.

The car does not have to be on the ground when you torque the LCA pivot nuts, you just need the LCA's in approximately the same position as they will be at ride height. So you can have the car lifted up to get at the pivot nut as long as the LCA is supported to place it at ride height.
