As I can see from the model of the drive, the Western Digital drive is a Helium hard disk in the HGST design. In the event of physical problems, helium hard disks are extremely problematic and also extremely time-consuming to process in the data recovery process. Just opening the drive without damaging it and without contaminating the inside of the drive can mean developing completely new tools from model to model.
According to your description, we are dealing with clicking noises, which strongly indicate a defect of the read/write heads and may also mean damage to the ferromagnetic surfaces.
All we can offer as part of our free-of-charge Economy Service is a purely external diagnosis, in which we can try to access relevant parameters using special hardware and software in order to be able to draw useful initial conclusions. This does not include opening the drive, which can cost (at least) a mid-four-figure sum.
As part of the opening, the drive interior is then examined to determine exactly what type of physical defects are present and whether conclusions can be drawn as to the extent to which data recovery might still be possible and feasible. And only at this point will it be possible to make a meaningful start on determining concepts for any necessary dismantling of the drive and the helium atmosphere required for this specific drive. It is also important to consider how certain components may behave when exposed to oxygen.
Data recovery in such cases is generally structured in milestones, so you will have to reckon with the fact that experience has shown that the entire process can cost up to 15,000 or 35,000 euros and take months before any actual success can be achieved.
