This is a Bosch "re-manufactured" starter, only 2 years / 30k miles old. I don't think it has worn out yet. I just had FLAPS test the starter, it failed the first test (solenoid) and then passed the next five or so tests. Solenoid seems to be the issue, and I cannot find any source for a replace

I would be more suspect of excessive bearing wear in the bearings that "cup" the armature. Once worn, flat spots and low spots result and can cause the kind of intermittent performance you are seeing Good standard practice is to read/record current draw of the starter during cranking over miles an
