Okay so if I make a left turn and let go of the wheel, it will self-center itself. If I make a right turn, I get "memory steer", the wheel does not self-center.

I know caster self-centers the steering wheel after taking a corner, however I've checked EVERYTHING! I'm pulling my hair out..

 

mine does this too... but i drove into a wall and messed up my alignment lol didnt before

 

It's just very strange because caster isn't "adjustable".. Hopefully someone can chime in.

 

You've never been in an accident, even a minor bump against a curb? When was the last time you had an alignment? Not much to say unless you can show us an alignment sheet.

You do have enough air in all the tires, right?

 

Alot of times its caused by bind in the steering. Either in the rack, tie rods ends, or ball joints. Something is out of wack and is getting bound up. check your strut bearing plate too.

 

Could also be the electric streering going out although when it happened to me it wouldnt return to centre after i turned either direction.

 

Are you on the throttle at all? Because that's the direction of torque steer. Just an idea.
