Just replaced my front struts and bushings. I used my impact for both nuts on top of the strut and already installed the entire assembly in the car. I found out they only need; I think about 20ft. lbs and I'm sure I overdid that. Can I loosen the nut and re-tighten to spec while the assembly is in or do I have to take it back out, get the spring compressor, etc. to loosen and torque to spec. Haven't driven the car yet.
