I have eibachs with tokicos.........anyways the front ones went in no problem.......I am having the worst luck with the rear ones though. When I try to tighten the center bolt down to the specified torque (23 pounds if I remember correctly) the shaft just turns with it. I posted this same problem a while back but the solution i tried did not work well. The solution was to replace my rear upper strut mounts........i got some brand new ones from toyota. I put them on, then a couple of weeks later i got my bump stop from toyota so took the same strut off and the damn strut mount was stripped out inside. When i got it, the inside of the mount was D shaped, when I took it off the inside of the mount was a circle. I have heard people say not to use an impact and torque it down with a wrench instead, but I am at the point now where i really just want this shit over with. Any suggestions/ advice would be greatly appreciated. Thanks guys
