1 Lucky Texan

Man, I dunno about an axle causing that type shake but, I might try just grabbing the axle and try jerking it around, do the same on the other side, go back-and-forth, maybe swap whichever one seems to move the most?

just realized - boots - so, pay no attention to me......

way to stick with it!

yeah, not unexpected to be tight in there.....if you could get something in there, just do it blind, assemble and try, then pull it out and try some other spot. Not as ideal as someting with easy access and powered-up on the bench....just grasping at straws.....

' plunge shaft ' yeah baby

^^^ good point. It's always a problem for marketing/data-collection folks. Self-selection. It isn't always a true snapshot of reality. You don't get info from folks who don't 'select' themselves to participate. It is also a problem with perception and expectations. If someone's previous car was a Fiat, the Subaru may seem stellar (no pun intended) but, if they are coming from a Lexus, they may be disappointed. Subarus, in some respects, are also like Jeeps in that, they often get used in a manner that exposes them to more risk of damage and severe situations.

I assume you tried more than one CD? The only other thing I can suggest is wacky and even if it works, likely shrt term. TRy putting some pressure on the circuit board with, maybe a piece od rubber eraser or lump of plastic. Try between mount points along each edge, then maybe near the center somewhere....if there's a cracked trace or solder joint, you may get lucky and close it up.

the same companies make units that accept the mini-phono plug too. Or, hit-up the classifieds here and at subaruoutback.org for a WTB on an OEM unit. somebody might pull one from a wreck or know someone doing a part-out....check local craigslist and ebay, etc. ???

^^^^ yeah, Scosche (?) and some company ' i-something ' make BT devices that inject into the antenna.

I have read that proper 'clocking' (timing) of the joints at each end in relation to each other is important to maintain max angle capability. there are some special axles - HIRO ??? - or similar that claim to have more extension , maybe more deflection? but, I don't think they enjoy a great reputation. built like these; https://www.amazon.com/Monster-Axles-Polaris-Sportsman-Scrambler/dp/B07QM254C8

I have no experience with them, but I think I have seen some threads about them at subaruoutback.org there was a user 'botenredwolf' that was sorta the audio guru for a while, but others may have data sources for you...?

I can't recall all the grounds but certainly, with an engine swap, it would be easy to miss 1 or 2 so, double check the straps to the intake mani, the grounds on the dogbone at the firewall area, the strut tower, I think the frame under the radiator? Also wondering if a bad wire in the body to hatch gaiter could cause some weird ness?

I think they still list the flash-codes from '83 up at; https://www.troublecodes.net/subaru/

would a '93 have a blink code?

well, Not sure my radiator has any specific ground wire. And yes, theory is not the same as practicality. But moving fluids do create friction and that can lead to static charge. Maybe measure from the battery or chassis ground, and a probe touching only the coolant. Maybe try with engine off, vs running at operating temps? Still, there are multiple formulations nowadays for coolants as well so, yeah - could be 'lost in the weeds' time.

cooling system electrolysis can be problematic I think.(haven't read-up on it, just seen it mentioned in the past.0 I could see where grounding the rad could be decent insurance to help maintain the coolant at ground potential.(relative to the engine)

yeah, came here to suggest refreshing grounds. if you could rig a vacuum gauge to observe when driving, might spot something when it misbehaves....?

you got it done so, movement forward is always good. the alignment numbers aren't horrible and they corrected the rear left quite a bit closer to in range, just couldn't quite get there.

I had to put the scissor jack above the rear knuckle to push it down just doing like-for-like swap on my Outback.

90*F today, another round of severe storms atm.

I think you want to KNOW, that with 'slight differential' gas pressure, there is flow OUT of the tank thru the vent valves. So, suck out of it, or blow a little pressure into the tank. Maybe borrow a WRX driver's vape pipe and use that smoke to confirm? lol

I THINK some folks have had issues with the commutator on the starter motor itself?

headlights? yeah,no ballasts. Some are designed to be rotated for best cut-off line then locked-down with an allen screw or ??? Others may require some creativity on the back side for heatsink or fan clearance. Turn signals may require a load resister or replacement flasher unit. Other installations are polarized I think. it is HIDs that need ballasts.

yeah, not close enough that they are gonna be making the 'time to pull the plug Doc' type decision when I'm dying, but those relatives didn't need/want the car. Still, best alternative at the moment. Really helps them out more than I thought due to coincidence of hail storm.Still, it may get destroyed by a teen driver......
