A friend of ours put some of that Blue Def stuff in her Silverado, but accidently put it in the fuel tank instead of wherever it's supposed to go.

Bad juju. Very bad juju. $15K worth of bad juju.

Ouch didn?t think would be that much in damage!

Yeah, I could see it being irritating, but for $15k, someone got raked over the coals pretty good.

So I got my transfer case all buttoned up, the clutch replaced, and finished the exhaust from the collector back. I had test driven around town a few times with all the shifter boots off and a hole through to the ground. Everything was fine as far as I could tell. When I finally got everything buttoned up (I had to modify my shifter due to the 1" body lift), I was excited to take it out and hear how the exhaust sounded without a hole in the floor. I drove my kid to school (1.5 mile round trip) and there was a noise. Not a good one. I'll spare you the trouble shooting and just get down to what it was.

This is the transfer case spinning with the transmission in neutral and the clutch engaged.


Here is the transfer case spinning with the transmission in fifth gear and the clutch engaged.


Not what you want to see when you drain the oil.

Here is the damage on the 4wd shaft.



The interference, and the noise, is coming from these teeth making contact.

[Irving]

Here's what happened. The first time when I had all three shafts out and was trying to juggle them all back together into the case, the 2wd-4wd hub clutch slipped all the way off the gear and the dog teeth shown in this diagram fell out. Well, one or two of them fell out. I didn't check their orientation before I removed the third one.


I looked at the spare case, but could only see a small edge of the dog teeth, using a mirror, and I determined the orientation from that. Well, I determined wrong and put them in backward. That caused them to somehow displace those internal snap rings you can see in the diagram and that was the strips of metal stuck to the drain plug magnet. Without those snap rings in place, the gear had enough play to cause the teeth to chatter together like you hear in the video. Thank goodness I still have that extra case because I was able to just take that entire 4wd shaft out of the spare case and put it into mine. In a record time repair (for me), I was able to pull the case, crack it open, figure out the issue, pull everything apart, and get it all back together, and installed in just one day. That is an absolute miracle for me. It once took me three days to replace a single seal.

Anyway, I've got about 50-60 miles on it with no bad sounds (that weren't there before anyway). A couple more trips around town and I'll drain and refill the t-case fluid again. Thanks for following along.

Oh yeah, I didn't know about this picture in the manual that I have. The guy helping me on the Isuzu board said he thought I installed them wrong, and by the time he posted that picture I was way past that so I just kept going. Lesson learned.

This is how we learn new stuff...

[Irving]

Pretty much. I could have paid someone at least $1,500 to do the clutch, gears, and exhaust for just the labor, but then I wouldn't have learned a thing or had the confidence to take stuff apart when I need to. Also, I wouldn't know that I need to replace my U-joints or that I've got some rust mitigation to take care of on the frame.

Should I just make an insurance claim on the rust? How does that work?

I did a 722.9 Transmission service done yesterday. This was much more difficult than previous 722.9 Transmission service due to vehicle being much lower. I had to use Ramp+bricks to raise the front and jack stand for the rear.
I go to rec center 4x a week, but my entire body is sore from doing this.

Not sure if you guys remember the crash pics from the 69 Opel my dad helped build:

But it's been resurrected. Just fired up the new 632 cubic inch 1200+ hp motor.

It?s back with a vengeance!
About a month and change ago, I posted up pictures of a wiring connector chewed up under the hood of my truck. I repaired the damage and thought I was good, Now I know it is a squirrel, I caught it when I opened the hood of my truck. It got away before I could get the phone out & get a picture.
This time, it built a nest and destroyed three wiring connectors and started to chew into the main bundle going into the cab through the firewall.
I even used that anti-rodent from Honda, well, it could have been some counterfeit stuff off of Amazon...... The damn squirrel ate almost all the tape and part of all three connectors and a lot of the plastic wire looms of three differing sizes. Guess I will have to soak everything under the hood with that lion piss stuff after I repair it again.
