What's the life expectancy of a metal shielded bearing?

Well I don't know where you live I'm in the US. Links are suggestions not written in stone it's just a suggestion to go ahead and replace the stock bearings with a link to a kit with all the bearings even bearings to replacing the plastic bushings in the steering bellcrank. Take your chances with the stock bearings that's up to you. Get the bearings from wherever you like I think some cheap China rubber sealed bearings are better than what come stock in some Arrmas.

Is this normal???
It can be but that pinion is pretty worn if you have not had that many runs on it. Quality of the material of the pinion can be poor dirt and debris can cause excessive wear. Pinion spur gear mesh could also be too tight. I would recommend getting the Hot Racing adj motor mount or the BLX adj motor mount to set your own mesh. Might also want to look at a hardened steel pinion.

It feels so weong a 0.8 mod pinion meches with a mod 1 spur....

Is this safe to use? Or its trashed
Looks fine to me but not sure how long it will be before you break the motor mount or slipper housing. Something has to give. Either the spur, pinion, or the bearings could go. Maybe the slipper hub or the chassis tabs that hold the slipper assembly.
