As a total lay person I decided to replace all motor mounts in my camry :)
I was not sure what to expect, and even if this can be done in the garage.

I put the car on two jackstands and lifted motor pushing on the oil pan
up with a screw jack and a piece of wood. Everything went fine with
almost all mount except the rear one.

I am able to remove 3 out of 4 nuts with no problem, but the 4th
(the upper one) is not accessible from the underneath of the car.
If I can fit the wrench there there is no room to turn it...
I tried from the top - no way, all stuff is blocking access to
this nut. Is there a trick to do it? Am I missing something here ?

I checked the Haynes book and they don't mention anything special.
The procedure for the rear mount listed in this book seems to be
exactly the same as the one for the front engine mount...

BTW - the old mounts were totaly damaged, no resistance at all.
The upper bar of the mount was totaly loose in the lower socket.
Is this possible I damaged the old mounts lifting motor up without
loosening mount screws? The book did not ask for loosening screws
but after I saw how it works I would loosen screw first and then
lift the motor up. This is how I plan to do it for the 4th mount.
But first I need to learn the trick to remove this last nut... :)

Please help!
