Hi All,
Sorry if this is a repeat thread but I read through 10-12 threads related to 100 series and a couple of 80 series threads. All of them were related to wheel bearings or front diff. Except this one 80 series thread which pointed to T-case and their noise went away after replacing T-case.
The noise I have is only during coasting, and goes away when accelerating. It is present at all speeds and very loud when I let go of gas. At highway speeds and when driving around the neighborhood the noise is same. I removed the front DS and it is still present. When coasting w/o the front DS if I shift transmission in Neutral noise remains but as soon as I shift the T-case in neutral it completely goes away. Does this indicate the t-case outer bearing is bad ? It also seems like the noise is coming from the t-case shifter area.
No noticeable play in DS shafts. Greasing the u joints does not make any difference. No driveline vibrations either just the noise when coasting.
Maintenance I have done in past 10k miles. All Toyota parts

- New Wheel bearings and spindle bearings
- New Rotors and pads front and rear
- New CVs and hub flanges
- Oil changed in all diffs and T-case, no shaving or excessive sludge. Oil mostly clear. Also just daily driving this right now has not seen the dirt or been off-road yet.
- Front and rear, upper and lower control arms.
