Having some trouble with steering wheel shudder that’s mostly noticeable at higher speeds when taking a long sweeping turn on the highway. There’s even lots of vibrations and steering wheel movement while going straight though. Even at lower speeds the steering wheel will tick back and forth. The worst however is when turning on the highway. It turns into straight wheel shudder. I’ve replaced everything imaginable. I’m aware of the EPAS issues on 11 and early 12 cars and the rack has been replaced out of a 13 boss. I’ve also upgraded the front LCAs to Steeda LCAs, different brakes, and new wheel hubs. It’s not a tire balance issue as I’ve had 3 different sets with the same results. I’m lost on what it can be and am contemplating the boss 302r steering rack as a last hope. One question though, someone has mentioned steering angle sensor. Could this be the root of the problem? Or do they need resetting at any point after replacing a rack? Other mods to the car include BMR performance lowering springs, with an adjustable panhard bar in the rear. Also camber bolts. Car has been on an alignment rack many times.
Other notes—changing the steering settings will change the severity of the shake. Sport will firm things up and make the shudder less notable.
—Also if this helps diagnose, the car needs a lot of feedback. Almost as if it’s trying to steer itself and I’ll have to gently hold tension on the wheel to keep it straight.
Any advice is appreciated or even shop recommendations. Hard to believe but no one in Vegas seems to specialize in suspension stuff and the dealer was lost.
