Don't do it, you could literally kill yourself, ask me how I know. I rented a spring compressor at Vatozone, it was my first time using it, and I put the spring on to loosen the springs to replace them on front. The funny part is I was loosening the bolt, I strut pointing at my face (had spring in between legs), and for whatever reason I thought to myself "oh wow I should really just sit on a tire and put spring against tire, and remove the nut", holy sh*t epicness followed, I put wrench on nut and span less than a whole turn, the spring pushed off the tire and shot out the strut in a loud BAM!, these were OEM OG stockers even after nearly 20 years had enough tension in the first 2 coils to shoot the strut a good 30 feet (atleast).
Yea so don't do it unless you know how to use one. /ubbthreads/images/graemlins/smile.gif
