Hello everyone. I've been lurking about for some time here, and I've always found wonderfully useful answers to a great many questions, so thank you all! In fact, I've never had a WRX question that I couldn't answer with a simple search here... Until now.
With 110k miles on my 2002 WRX Wagon, that memory-steer issue that many of us are familiar with began to get worse, so I threw on a set of Whiteline Steering Rack Bushings. Before the bushings, the memory steer was pretty much as everyone else here describes. The install went great - frustrating like everyone says, but without complication, and the steering response is much crisper.
But now... Lets say I take a freeway on-ramp somewhat spiritedly, involving a RIGHT turn. When I get onto the straight, if I hold the wheel dead center, it tracks true, but if I loosen my grip, the wheel pulls itself LEFT and the car tracks left accordingly.
Once this condition exists, if I perform a similar maneuver at a similar speed in the opposite direction, it'll even out and everything will look/feel/drive true until the next spirited turn. It's completely tolerable when I'm driving track days and auto-cross, but this is also my daily-driver, and holding firm on the wheel for long highway stretches gets old quick.
The fact that the car now tracks precisely with the steering wheel makes me think the steering rack bushing install was fine. But the car pulling in the direction opposite to the most recent aggressive turn... I'm at a loss as to what to upgrade/replace next to address this, and I could really use some help here.
