Metallic Rattling Sound + Clunking Sound?
I owned a Grand Prix GT for 3 years and new that car inside and out, but this Cobalt I just bought is strange to me so it seems it's time to seek help. I just bought a 2007 Cobalt LS coupe a couple months ago. So far I've replaced both lower control arms(and ball joints) because the bushings were completely destroyed, replaced the thermostat because it was getting stuck open, got an alignment and wheel rotation, and after a suspension inspection for the alignment the mechanic said it should be good to go and I just need new brakes(which I will do myself). However I'm hearing two distinct sounds. One is a metal clunking sound at low speeds, which I'm assuming is likely my sway bar end links because I can move them around by hand fairly easily on the driver side. My grand prix's sway bar just bolted to the control arm, so it just broke when it went bad so not sure what a bad end link sounds like. However, I also have a weird metallic rattling towards the front driver end. It almost sounds like something is loose or even like a piece of metal is sitting somewhere and rattling around at low speeds. I haven't noticed it at high speeds, mostly just at low speeds and it seems maybe just over small bumps. I jacked up the car and took the wheel off and looked everywhere. Everything seems to be fine. No play in the tie rod, control arm looks fine, ball joint looks fine, all bolts are tight, I can't see anything that might be broken. I also don't notice any difference in driving. Steers straight, doesn't pull, brakes fine, no real issues. Not wanting to waste my money to get it inspected again just to be told they don't see anything so any input would be greatly appreciated. Thank you!
