Might as well, and the tank strap bolts/ nut clip things. They seize up sometimes and when you try to remove them they strip out. Sorry I don't have a p/n.

Dorman (oh, well) 55157 for the tank strap bolts and nuts. The fitment apps might say they don't fit, but they do.

Swapped out the front and rear differential fluids just now. I used Mobil-1 synthetic, and had a great time. Here's a pic dump:

I did mine like 30,000 miles ago, but I didn't drop the spare. Did it give you a lot more access?
I don't remember it being in the way, but that doesn't mean much since it was so long ago. Haha

Got the Nintendo switch connected to the rse. I am surprised to learn that the factory headphones don’t work for the audio. I have to use additional wired headphones. That’s bull$hit!
Plus, my little power inverter has two USB ports so I used one for my HDMI to RCA converter. That power is not clean and the audio has a hum. I have to plug it in somewhere else…WHAT A PIA!

Odd, we've used an Xbox1 connected and the IR headphones worked. Did you try flipping the A/B switch on the headphones?

I use a pure sine wave 300w max inverter plugged into the 12v outlet by the RCA ports and an RCA model DHCOMF HDMI to RCA adapter plugged into the aux ports. It doesn't need auxiliary power. Kids use the 2 USB ports on the inverter to charge their phones.

It is odd and I tried about everything I could think of. The sound works becauseI can source it with the head unit and play it over the speakers in the truck but I can’t get it to go over the factory wireless headphones. I can hear sound with the DVD we have in.

It did help me have more space to maneuver. I'm sure I could have done it with the spare in place, but I was laying on my yard and it is slightly higher than the section of the driveway where I parked.

It only took a minute to drop the spare and slide it out of the way.

Ninja Edit: If I was going to do it again, I would have spent 10 minutes grabbing the pressure washer, and clearing out the chunks of dirt from under the front and rear diffs. Ah well, such is life.

I dicked with this more this morning. I just can't get it to work. The RF headphones only play for the DVD sound. I can get the AUX input sound over the speakers in the truck and through the wired headphone jacks in the RSE but not through the IR headphones. Only thing I haven't tried is the third row screen and IR headphones.

They've also used them to listen to mp4 movies I've had on a SD card plugged into a portable DVD player that was plugged into the Aux line in while watching on the flip down screens

What’s missing in this photo? This is
BDF0F6C0-273D-449F-B6FA-DC7B22A5B498.jpeg
the FSCM or FPCM that runs the fuel pump. Located under the floor just forward of the fuel tank. My shop manual says there’s a cover over the module, but mine is naked.

If anyone’s familiar with it or may care to post up a picture of theirs?

I am trying to decide of it’s anything worth seeking out to replace if it provides any real protection. Or is it just a flimsy cosmetic cover? Or maybe it was never there? Thanks for any feedback!

I dedicated a lot of time to some mods on my Tahoe this weekend. I replaced my low beam halogen lights with one of HID Guy's kits, plasti dipped my chrome surround on my grille, tried to repaint my front bowtie (FAIL!), replaced my interior lights with LEDs, installed my holster under my steering column, and replaced a seatbelt latch on the driver's seat. Now I'm waiting on my rear door actuators to come in as well as the billet bowties I ordered. As soon as they get here I'll get to installing them too. Long weekend but I got it done. What did you do to your Tahoe/Yukon?
I buffed out the headlights!

There wasn't anything on the one on my 08 Silverado but that truck is far from stock. maybe someone else has messed with theirs.

I guess my kids were just wearing them to keep their ears warm while they were playing their game with no sound

They've also used them to listen to mp4 movies I've had on a SD card plugged into a portable DVD player that was plugged into the Aux line in while watching on the flip down screens
I believe you that it worked for you. I cannot get sound through ours when using the RCA AUX for the life of me tho. I wish I knew why.
