Replaced all of my 97 Avalon's cluster bulbs one year ago. This was my first time (150k mi) and would like to offer two pieces of advice. (1) Make sure they're pushed into the holder as far as possible, or vibrations will shake them loose( ask me how I know). Got around to the same task one year later and cracked the left vent cover trying to remove it.(2) I put small coating of lithium grease on all of the clips when I replaced them. Hope, if I ever have to remove the cluster again, the pieces will snap out a little easier.
