heat/ac actuator
if its when you are breaking it is possible it could be a rotor if you hear like a roaring or grinding noise coming from that side also could be a wheel bearing
More than likely the sway bar links - TSB on these
the noise coming from this truck is the uv goints
Have that tire checked sometimes the belts inside can break and cause a thumping noise
Open the glove box and let the squirrel out!!
Front hubs my be wearing out.
A thumping noise on your Hyundai Sonata that accelerates when you go faster might be a tire balance issue or a tire that is coming apart. You might also have an issue with the tie rods.
Could be the brakes are gone or it could be a hub and bearing assembly about to fall off the front of your car.
it could be the idler puller rubbing on the bearings. we had to replace it on our 2006 Chevy trailblazer ext.
