It's somewhat easy to swap springs on these, as done by Inertia Lab. But to rebuild, as in valving or camber plate repair, nobody is doing it. There are no individual parts from GM. I've dissected these front DSSVs. Aftermarket dampers most likely won't pass an OE validation for durability. That statement is comical in that it is pretty evident the Multimatics shouldn't have passed either.
-Noisy/loose camber plate to strut... there is a large nut keeping the ball stud tight to the strut insert assembly. The only way to access it is to disassmble the entire insert assembly. Doing this means the gas charge is lost. That loose nut to ball stud can have enough play that the gas charge is lost anyway. Also. sometimes it is not the large nut causing the noise. Where the ball sits within the camber plate there is a nylon bushing. Sometimes this wears out. There are no replacement parts.
-Noisy insert assembly. This can often be fixed by tightening the bottom nut. But there is also an internal nut on the other side of that visible nut that would need to be set correctly.
- Leaking grease. This is normal. There is grease within the DSSV struts for the strut insert movement. There is a breather on the strut that can vent excess grease. GM has a TSB on this. It was also common on the Gen5 Z/28 DSSVs.
