Vibrating While Cruising at Highway Speeds, Among Other Things. Are They All Related?
Hey everyone, I've got a new problem that started happening last night.
I have a base model automatic 2005 Cobalt Sedan that starts trembling while cruising at 60mph/~2300RPM. I feel it mostly in my steering wheel, accel. pedal and, well, the entire car. I do not know what gear it's in. Occasionally, almost seldomly, my steering wheel shakes when I'm braking from similar speeds. Other than that my brakes work normally and smoothly.
Now, I have also been experiencing a noise coming from the Driver's front wheel. It's almost a metallic brushing sound, as if there's iron wool inbetween the rim and the brake. This usually happens after braking once or twice then getting back up to 30~40mph. Turning affects it and sometimes turning abruptly causes the noise to cease. People have suggested many things regarding this noise, telling me its the screamers on the brake pads or wheel bearings to the left control arm or the rotor rubbing with the backplate. I can't recreate the noise while its in lifted up in neutral, either.
What I've done: About a year after I've owned the car I sent it in for the power-steering recall, if thats any help. I've also recently slimed my tires because their pressure was dropping unusually fast. The slime helped out, and their pressures are sitting at ~40psi. When I torqued the tires I did the stars properly and torqued the lugnuts to about 80NM.
TL;DR: Car trembles @60MPH/~2300RPM. Steering wheel shakes occasionally when braking from similar speeds. Driver's front wheel making brushing sound after braking and accel back up to 30~40mph. Turning affects it, somtimes removes altogether.
BIG QUESTION! Are they all related and better yet, how do I fix? If you need more data regarding this, I would be happy to provide. Also, I don't know a lot about cars. Haha, otherwise I probably would be out troubleshooting more!
