Are you referring to the three nuts that secure the damper assembly to the frame? If so, it's 43 lb.-ft. using new nuts.
Did you replace the front sway bar bushings? If you didn't that is the most likely culprit.I am getting a knocking noise, replaced struts; sway bar links, front control arms and engine mounts. Driving me nuts. Trying to see if anything is loose.
Looking for specs on all strut bolts.
