I used the puller tools on mine, but got impatient. One of the tools slipped, caught the lens and snapped it in two! $372 later, I was installing a new lens.

Pushing from the back is probably safer, but if you do use the pullers, be careful.

Also, when you do get the cluster out, don't yank the harness off unless you've already disconnected the battery. Otherwise, you'll trigger the SRS lamp, and you'll have to get the dealer to reset the code...
