I disassembled the zoom lens so I could remove the dust behind the glass. It is possible but both disassembly and reassembly takes a lot of patience and instinct.

How to replace the front-lens of the zoom-lens, when it’s scratched!?!

Tom de Hoop - 06/04/21

Ok I removed the defective one, but my question now is: what model of lens can I replace it with? Is it compatible with any lens from Nikon, or from other manufacturers?
