Suspension Torque specs

Hey all, I’m swapping the front air suspension with factory replacements, Bilstein.

I am also do the sway bar bushings, and sway bar links.

Does anyone have the torque specs for the strut mount, the bolt connecting the strut to the lower control arm, the sway bar links, and bushings?

I’m not wanting to over tighten and strip anything.

Thanks I’m advance!!!

They are big steel bolts going into big steel nuts. I never bothered with any specific torque specs. Just yank 'em gutentite.

I don't think that is necessary for strut replacement.

However, if you keep the clamps tight on the swaybar, yes those bolts must be tightened at ride height.

I had a quick question. Do any of the bolts have to be torqued down while the car is at ride height?

Do I need to do this for all the nuts and bolts or only some of them?

It's for bushings that rotate. This is generally the bolts on the frame, not the steering knuckle. Not needed for ball joints. Almost for anywhere where the bolt is horizontal vs vertical. Look up "properly clocking" control arms. There's some good videos explaining in YouTube.
