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

have a look here: https://www.icarsoft.com/Article/s-269-269.html a reasoned step-wise diagnosis and treatment for your code

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?

My 2008 ran like crap after high humidity/cool conditions. Was ready to change out coil pack and instead dried out the interior contacts of the pack where the wires plug in and sprayed with WD40 and all was well. Have you tried spraying water around the wires when dark outside with car running to see if there are any sparkly light shows? In my case, I didn't have the light show but the rough running was related to the damp coil pack. Fingers crossed for something simple.

alternator?
