Hey gang. I'd like to think I'm somewhat a common sense type of guy when it comes to cars and fixing the things. The car "sometimes" shakes at high speeds around 55 to 70. Obviously alignment!.....Nope. Had it done and supposedly its right. Tire pressure - good. Checked the tie rods and all joints - good. Shocks are a bit shot but Im not thinking that would be to much of an issue on that? Tires are newer tread. So Im stuck. It comes and goes. I could be cruising along at 65 and having a good shake for 5 miles then smooth as a whistle for the next 10. By the way its a 2004 Aveo. I did notice the left front left wheel bearing is starting to give me that "hum" a sligh5t bit telling me that's going to need some attention soon to yet its no where close to needing opened up to give me any kind of issues like this.
