Today while driving , the upper ball joint separated from the control arm, causing the truck to pull hard to the right. I was able to keep from wrecking the truck. While doing research it seems that this is a common occurrence with the Silverado Trail Boss and the Sierra AT4. I read a safety recall report on these vehicles, 21V‑718, after reading this, it's exactly what happened with my truck. Ball joints is rusting and corroded. Vehicle is able to be inspected upon request. If I had been on the freeway traveling, it would have caused a severe single or multiple car accident as I lost control to steer. No symptoms leading up to the situation.

While driving down the interstate hi-way, I heard a pop and my truck started to swerve into the adjoining lane. I turned the steering wheel in the opposite direction and the truck started making a rubbing sound and very hard to steer. I finally got it to the side of the hi-way and seen my passenger side front wheel leaning in. The upper balljoint/control arm broke. Luckily no-one was in the lane next to me or it would have caused a serious crash.
