Possibly clogged cat converter(s)? Broken bit's of the honeycomb will follow gravity and clog the exhaust when car is heading up hill. The noise will startle the neighbors but if you can disconnect the cat(s) and test drive, that will help in diagnosing this issue. Buddy had this issue and just emptied the broken bits and drove on.

So is there no deteriorating catalytic converter potentially contributing to clogged exhaust? Saw it on a Ford van years ago. Ran it loud and proud to diagnose a clogged cat.

Did the p0420 code go off by itself or did you reset it? Keep us posted if it returns.

what was your catalytic code? was it the P0420

Very clever. So rather than continue to reduce your hoarded inventory of Subie parts, you intend on hiding it in plain sight from your wife in the form of a Baja?

I bought an aftermarket shaft for my 05 (I think) now sold that worked out just fine. I will search my posts here to see what other info I may have posted. check out Parts Geek. They have some for Auto at $300+ https://www.partsgeek.com/catalog/2000/subaru/outback/driveshaft_-ar-_axle/drive_shaft.html?rp=driveshaft

Do you feel it under the seat when the vibration occurs. Something similar in mine turned out to be drive shaft. Got an aftermarket since the u-joint was not replaceable and all was good.

if near front ps fluid?

Would love to hear from anyone who did rear brakes on 2018+ Want to know how far up Shitz Creek I'll be heading before starting out if this ordeal can be expected (or avoided.)

2 years ago I was in Lake Placid NY overnight -30F Alternator screamed like a banshee in the morning. Went into local Autozone and clerk said to wait til noon when temps return to tolerable. Followed his advice and all was good after a late breakfast. Before jumping to conclusions, I suggest pancakes and bacon.

From your title, I thought "Tow" was referencing towing the car not "Toe" 😀

drive shaft U joint?
