easiest thing to do is take the hub off and tap them out with a hammer but put the wheel nuts on so you dont damage them incase you need to re-use them
What spacers & bolts did you buy? I need to do the same to mine
you can do it on the car
turn the hub until a gap appears at the back, toyota designed it for the very purpose
a quick sharp blow from a lump hammer should loosen them
Have you managed to do that before? Just had a feel around the mud shield thingy behind the discs and I couldn't feel a suitable sized gap? Would be very handy if it was this simple though, can you show me (pics/drawing) where the hole is located mate?
