Advice on Rear Shock Mount + Shock DIY

[TurnAround]

Thanks Kirstophe

Hey, do you remember if there's a second shock strut nut that goes underneath the RSM assembly? Put another way... I'm confused by something; I can see where the upper center nut keeps the shock piston from going 'down' through the RSM (works when the wheel is headed down), but what keeps the shock piston shaft from traveling up through the RSM when the car's wheel hits a bump? The RSM just seems to be a 'pass through' passive rubber bushing, but in order for the shock to work in both directions it would need to be solidly nut/bolted into place from both the top of the RSM and the bottom.

All the pics I've seen just show one nut at the top. How the heck is the RSM held firmly in place at the top of the shock shaft??

Put yet another way.. I'm wondering if the noise I'm hearing & feeling in the center of the RSM is simply that there's a loose lower nut that normally sandwiches the RSM plates, and its got play in it, hence the bumping?

Any pics of the total assembly?

Thanks
