I've have a set of AMS coilovers, they are a few years old and am noticing some play (up and down) in the shock or spring when the vehicle is up in the air, the preload is set fairly high and dampening is about 75% stiff, this problem is reduced slightly at 100% stiffness but the issue is still present. I do not have this issue on the front and it is occurring on both L and R in the rear.

Can you please see the two videos below for a depiction of what I am experiencing. I have been getting excessive wheel hop and when inspecting the rear I found this, this is the only play I have in the rear end now.

For reference here is what my rear-end build is:
Z1 Toe Arms (less than 1 year old)
AMS Camber Arms (bushings replaced < 1 year)
AMS Traction Arms (bushings replaced < 1 year)
Energy Suspension Diff Bushings (bushings replaced < 1 year)
Eibach Sway Bay
SPL Endlinks

Thanks in advance!

Ok so it’s hard to see what your talking about in the video because I don’t see any “free play” but I’m thinking your saying it’s undamped movement? Looks like it’s topping out harshly? If I’m seeing that right then that would mean the shocks need a rebuild because they have an air pocket in them. Best simple way to check is pull the coil over and remove the spring and see how the shock moves.
