Struts on the old, rwd Toyotas are stupid. They weld the spindle onto the bottom of the strut. This makes it very expensive (or scary, if you're the type who cuts and welds on pressurized cans of flammable fluid) and extremely annoying when a strut wears out. Further, Toyota, in all it's infinite wisdom, decided to make that spindle/strut arrangement slightly different for all 943,000 variants of RWD Corrolla/Celica/Corona they made from about 70 to about 85.
The other PITA I have personal experience with is the in-dash fan motor on the old Volvo 240s. Volvo evidently believes an insecurely mounted blower housing can cause worldwide famine, venereal disease and the plagues described in Revelation, because they attached it to the dash and firewall with no fewer than six metal brackets. We fixed two of these, the first took 5 hours and the second took 3 hours.
