Finally began the install on my front facing bumper camera. Got the camera in place and wires run through the firewall. That's as far as I got before the rugrats dictated that I pay attention to them. Lol.

Also ordered a new remote on Amazon, since the newly turned 3 year-old rugrat put my key and remote down somewhere in Walmart the other day. (Obviously my fault, as I should have kept a better eye on him with them, or not agreed to let him hold them to begin with.) That should be here tomorrow, and I'll get a couple new keys cut sooner or later. Already had a couple GMC blanks sitting around waiting to be cut.

Where's the cheapest place to get a key cut? I have a 2005 tahoe so I'm assuming the key has a chip in it. Hate to have to pay a lot to get some spare keys.

My '05 has no chip. When I bought my Yukon is only came with one very worn non-original key. I didn't want to make copies of a smoothed out copy so I went to a GM dealer and they cut me a new key for $20 after looking up the key code using my VIN. I then took that crisp new key to home depot and had four more spares copied for about $3 each.

Technically last night, but I changed the fluid in both my front and rear differentials and the transfer case. While I had it apart I installed a new cover on the rear diff and used a LubeLocker gasket when I put it back together.

This was my first servicing of the diffs and transfer case since buying the Yukon. The rear diff fluid looked fairly clean, and had been serviced before at some point. Only a little metal dust on the magnet. The front diff appeared to have never been serviced in the 160K on the vehicle. The fluid was dark and opaque. The magnet was covered in a thick layer of fuzzy metal shaving, but no metal chunks or chips.

The transfer case fluid looked clean, but the big surprise was about a quart of extra fluid came out when I opened the fill port before draining the case. A little research suggests that I have a bad input shaft seal on the transfer case and ATF from the transmission is making its way in. I always check the ATF level before I head out to tow (it's on our departure checklist) and have never seen the level drop. I'll keep an eye on it now since the level in the case is where it should be, I'll see how long it takes to loose a quart of ATF. I guess that's another thing to add to my to-do list.

Any thoughts or suggestions on how and when to deal with the transfer case seal are welcome on the thread I had going here:

My 06 doesn't have a chip. You can have keys cut at any hardware store, but I'm taking my GMC blanks to a local locksmith and having them cut because the big box stores will only cut what they sell, and their blanks are actually Chevy blanks that are a tad longer than GMC blanks - the spare we had cut at HD we have to pull back just a smidge to get it to work in the ignition. Bit of a pita. Compared the Chevy blanks I'd bought for the Suburban I had with the GMC blanks I bought for my Yukon, and sure enough the Chevy ones are longer. Found the same to be true of my husband's Colorado keys, both original and copies. Just an fyi for you fellow GMC people.
