Engine ticky-ticky-ticky sound at idle (2007 Tahoe 5.3L, 135,000 miles)

Thanks to these guys here, I found it. I made some videos on how I did this, I’ll edit the clips and publish on YouTube. I didn’t take transmission and transfer case all the way out.

Wow. Can't wait for this video.

Ooooh, that was a close one....

Glad you caught it, and I can't wait to see the videos either!

Did you have to remove the drive shaft, or just undo it from the rear diff?

Just for this you should be bumped up the the next level above TYF Newbie

Rear drive shaft and front drive shaft at both u-joints at the differentials

I saw a couple loose manifold bolts under there, I will tighten them on the next oil change. Thanks for mentioning that earlier.

Mike, your amazing. Necessity is the mother of invention. It took me like a week to do my rear main seal, and I have a nice climate controlled shop with painted smooth floors and a lift. You da man!!!

I have to ask? what did you use to loosen and tighten the torque converter bolts? I had to buy a stubby 1/2" drive air impact and a swivel socket. The torque converter bolts had lock-tite on them from the factory. I used the blue lock-tite when I went back together.

I think another day or two of driving it with the broke flexplate and things were gonna get interesting.

Good save

I used two 15mm combination wrenches hooked together and applied a solid 4-4.5 grunts of force.
