Let me just add that if you don't have an impact gun then the lower strut bolt will be a serious pain. I was able to break the torque on it by placing a 22mm wrench on the side closest to the front of the car. Get it on there good and make sure it stays aligned during the whole process. On the back side go at it with a 19mm socket, 12" extension, 1/2" ratchet, and a nice size pipe. While yanking on the bar make sure the 22mm stays wedged in and give it a tug. Good luck.

Yes indeed, a nice long breaker bar and a 6 point socket set is all I needed to get those bad boys off. If you can imagine I originally attempted this with a 12 point socket! Trashed the nuts. Had to order new ones from Nissan.

How do you pull out the spring after lower perch down?
Do you need to use the spring compressor?

How much torque do you use to loose the 14mm nut holding the strut top on? I have a impact wrench 250lb of torque and is not loosening it ? The springs is compressed also.

you have to compress the spring more and use a wrench to hold the piston, not just spin it like crazy.

It was really easy to remove mine. my battery powered impact was able to get those out easily. try compressing more?
