I want to remove the composite rear bumper from my 2004 nissan

To remove the rear bumper cover on a 2008 Nissan Quest, you can follow these general steps:

1. Prepare the Vehicle: Ensure that the vehicle is parked on a flat surface and the engine is turned off. Put on safety goggles and gloves to protect yourself during the removal process.
2. Locate the Fasteners: Look for the fasteners securing the rear bumper cover. They are typically located underneath the bumper cover, near the wheel wells, and along the bottom edge of the bumper.
3. Remove the Fasteners: Depending on the specific model and trim level, the fasteners may be screws, bolts, or plastic clips. Use the appropriate tools, such as a screwdriver or socket wrench, to remove the fasteners one by one. Turn them counterclockwise to loosen and remove them. Keep the fasteners in a safe place for reinstallation later.
4. Disconnect Electrical Connections (if applicable): If your Nissan Quest has any electrical connections, such as sensors or lighting, attached to the rear bumper cover, disconnect them carefully. Look for connectors near the edges or inside the trunk area. Gently detach the connectors by pressing the release tabs or using a flat-head screwdriver to release any locking mechanisms.
5. Release the Clips: Once the fasteners are removed, there may be plastic clips or tabs securing the bumper cover to the vehicle's body. Carefully pry or release these clips using a trim removal tool or a flat-head screwdriver. Take care not to damage the bumper cover or the vehicle's body.
6. Remove the Bumper Cover: With all the fasteners and clips released, gently pull or wiggle the rear bumper cover away from the vehicle's body. Start from one side and work your way to the other, ensuring that all connections and clips have been detached. Be cautious of any remaining electrical connections as you remove the bumper cover completely.

Please note that the exact steps and fastener locations may vary slightly depending on the specific trim level and optional features of your 2008 Nissan Quest. It's always recommended to consult the vehicle's owner's manual or a professional technician for more precise instructions tailored to your vehicle.
Take your time during the removal process to avoid any damage to the bumper cover or the vehicle's body. If you're unsure or uncomfortable performing the removal yourself, it's best to seek assistance from a qualified technician or a reputable automotive service center.

If you pull the trim off (use a plastic spatula to get under it, then just yank with your hands) there are holes in there to reach the bolts.

Get an extension and a socket, I think it's 12mm, and then see if you can just tighten them up a little bit.

Also, the bumpers hang on the body with some clips/grooves along the edges, so make sure that they didn't 'fall out' of the grooves and clips and sag that way.

If so, loosed the bolts, pull the bumper away from the car an inch or two and then push it back in place while aligning the bumpers edges.

Lift the tail gate. There are clips or screws along the top edge. Remove this. The clips all you do is pull the center pin with a panel tool or pliers then the rest will come out. Then you will need to remove the clips holding the rear side of each of the back wheel wells in. Under that will be more clips, screws or bolts that hold the side edges of the bumper cover on.

I assume you mean the bumper cover.

There's a set of two-piece plastic clips along the top of the bumper. Pry the center section out then the outer piece can be removed.
There's more clips along the bottom LH and RH sides.

And, there's an M6 bolt in the top of wheel arch end of the cover.
You should then be able to remove the cover.

The bolts to remove the bumper internal are now accessible.

Further down you will see a diagram of the bumper removal.

remove the two bolts under the hatch, the four plugs along the bottom edge, and the plate light. Don't forget the red circle clip or bolt on the diagram. Then you just pull it off.

1. Open the trunk.
2. Remove the rear compartment sill plate. (Trim round the back edge of the trunk)
3. Pull the left and right compartment side trim panels down to access the fascia bolts and nuts.
4. Remove the tail lamps.
5. Remove the fascia bolts and nuts from the rear bumper fascia 1 nut 1 bolt on each side near tail lights.
6. Remove the push-in retainers from the top edge of the fascia.(4 plastic circles, pull up on center of cirle with screwdriver
7. Raise and support the vehicle.
8. From underneath Remove the push-in retainers from the rear bumper fascia (one on each side I think)
9. Remove the fascia bolts from the rear bumper fascia. on on each side from, up where the facia connects to the quater panel)
10. Remove the rear bumper fascia from the vehicle

Under the rear wheel wells, along the edge near the back is a screw. There is one on mine but there be more than one. Remove the screws for each.

After this, pop the rear trunk and look along the edge of the trunk right where the trunk hood meets the trunk itself. There are three black plastic screws that hold the rest of the rear bumper to the frame. I don't know exactly how these screws work but they don't just unscrew - I had to pop them out with a screw driver instead of rotating them out. Once those are out the rear bumper will lift up and off. There are some hooks along the rear wheel well where you removed the screws - you need to lift and pull out these edges, then lift the entire rear bumper off from the middle of the rear bumper.

Once you've done this, it goes pretty easily. If you have no problem with removing the black plastic screws or unhooking the edges, it should come off in less than five minutes.
