I know I have seen this before somewhere, there is a special socket that allows you to remove the top nut on a shock when doing a spring/shock install. The reason for the socket is that the bolt on the shock can twist, making the nut difficult to remove without a true impact wrench.

I swear I saw this on some car forum, I searched our site and Miata.net with no luck. Let me know if any of you guys have ever seen this. Thanks,

 

you can just use an open end wrench on the nut and a metric allen key to keep the piston from spinning while loosening the nut...

 

I've tried this but its alot easier said than done

 

just go buy some air tools and it takes like 2 seconds
