If you don't mind making a huge mess...empty lot + dish soap/water mixture all over pavement should give you a nice slick to activate ABS. Just be careful :(
I was having his same problem with mine. The wheel cylinders were leaking into the boots. Whenever I would bleed, it would just pull air through the wheel cyclinder and out the bleeder screw. I was using a pneumatic bleeder though. Worth taking a look at, replaced wheel cyclinder and it...
Just a heads up, there's a post somewhere about fixing the worn throttle body shaft for like $5 in parts, it's just a few washers or something. I can't remember if it was on T4R or YotaTech or something. But it's a guy who pulled his, and could visibly see that the butterfly was offset...
The suspension is factory? No way the coil could have been turned slightly? Mine made wonderful sounds for a bit because one front coil would contact the UCA going over bumps. Adjusted the way the coil sat on the strut and it was good to go.
This sounds like drive shaft greasing. Get under there and find all the grease fitting on the driveshafts and get them lubed. If you've done any kind of lift, the slip joints may take quite a bit of grease.
