Finished this today, with new knuckles, wheel bearings (Timken) and reman axles. Went with Cardone 60-7355 remanufactured axles. The ones I got are NTN/OEM remans, and they have currently cured the vibration while stopped in drive that I was having before. Old axles were completely different to the OEM ones (see my thread for pics). It's much easier and faster when you know which bolts will come undone...Yep, screw extractor is stuck fast, even to the attentions of an air hammer. So going to order new steering knuckles, wheel bearings, CV axle, front disc shield and probably tie rod ends (can't currently get the cotter pin out there).
What's the current best guess for reman or aftermarket new CV axles? I already have non-Subaru ones, so new ones won't make vibration when stopped any worse.
Also did an oil change and fitted an oil change valve.
