Default Vibrations coming from wheel/wheel well/engine bay

I have not yet diagnosed where these vibrations are coming from, but solely from ear it sounds like its originating from the wheels. I measured the psi settings from each wheel, and they were bot hon their appropriate settings. I also looked underneath the car to see if i was dragging anything, again to no avail. Anyone know if I may have a bent wheel? The vibrations seem to be more of a roll, lump, roll lump, as if a circle now has a straight line in it. This being said, the sound is not constant - it comes and goes seemingly whenever it wants to. I've also heard this same noise while traveling on the freeway about a month and a half ago, only to return tonight. Any help in determing the possible source of this sound would be appreciated. Thanks in advance.

hmm sounds like youre going over the break (Section) on a road?
or check the inner side of the tire for bubbles or lump on the tire.

I dont think its the road, because it happens on regular residential streets as well. I will check, however.

do you have alloy wheels?

what speeds does this happen?

are you lowered?

any stereo boxes or anything?

hows the tire wear? an scalpoing or flaring?

good, analytical mindings, fs.

suggest you jack up the wheel. check for any looseness (grasp and shake tire)

then rotate the wheel to look for out of roundness or other defects already mentioned.

if the problem were always present at particular speeds we'd suspect wheel imbalance.

-could be a tire in failure mode, possibly-

I just took it out for a quick drive and the sound seems to be just a sound, liek a rattle, but it gets worse as i turn either right or left (but moreso right).

PS: it makes a popping sort of noise.. like something is stuck; only If i could pin point where it was coming from. BTW, this sound now seems like it was started yesterday (even though i only drove it once and NOT over a pothole then).

Have you looked at the boots on your CV joints. It doesn't take but a little dirt to ruin a CV joint. It will cause it to pop and crack, more so when turning.

The problem I've found with my xbox (automatic)
I get a strange rattle/noise while on "Drive" with my foot on the Brake. Once I let off the Brake...no noise.

Anyone else notice this problem?
