so currently mid-install on some tein s-techs on my tC 05'.
ive im the front 2 and at this step

the 19mm bolt with lube on it on top the assembly when spun is just moving the entire assembly down to the springs. its spinning all the plates instead of loosening the nut. we're using a craftman decent sized socketwrench an impact wrench is on the way but im thinking it'll just spin all the plates faster... any ideas.
:pray:

you need to compress the spring to get the tension off the top mount. also i think the top nut has an allen head hole in the top so you can hold that while you turn the nut. hope this helps good luck.

got it off with a wrench and put the new springs on but when we put it back into the car the anti roll bar end link to the strut body doesnt lineup its about 2" short, cant figure out the problem any ideas

use a floor jack or strong friend to lift up the wheel assembly. or lower the car a little while supporting the wheel assembly somehow. like on bricks or strong friend haha.
