It is probably similar to the Traiblazer.
Remove grille and headlights
Remove pushpins along the bottom edge of the bumper and the one on each lower corner near the wheels
Remove pushpins along the top of the bumper underneath where the grille was
Disconnect side lights/fog lights/etc
Pull the bumper straight off the front, taking note of the built-in clips near the top (take a look from under teh bumper, you'll see what I mean)
That's the basics of it. I can take mine off in about 15 min.
Yes, the Envoy is very similar if not exactly the same.
Sparky, If your process above refers to these then I didn't understand, and just wanted to make it clear.
There is a locating pin on the front lower area of each fender inside of the bumper cover rearward of the cornering light that slips into a guide, that guide is designed with a retaining latch that needs to be released so that the bumper cover end can be slid forward and off of the pin.
These guide/latch parts are glued/fastened to the inside of the bumper cover and often get damaged in an accident. The result is the bumper can come off of the pins without needing to release them (latch finger is damaged or missing). Or the entire guide/latch gets detached from the bumper cover. Damage in this pin mount area often causes a large gap.
Be careful not to damage the guide/latch by just yanking.
Once the cover is off, you may find the pin and its mount bracket located on the front bottom of the fender is bent, (mine was) and you can tweak it upwards a given amount to reduce the gap when the cover is installed. Some gap is normal.
