I recognise this problem as a mechanic however, most changes I have seen make some sense. Having said that I notice of late that I am having to purchase pre assembled parts 'modules'.
For example, one day I purchase a wheel bearing, a week later that bearing is no longer available, I have to purchase it all assembled with other conponents.
Bearing carrier, hub complete with wheel studs, ABS tone ring, ABS sensor,.......oh and the bearing!
40 euros becomes 250! I get it that there is just one part number so one parts bin but, my poor customer has to foot the bill.
