Problems in front end
There has been a humming noise coming from under the front end. At higher speeds it gets louder, but there is no difference in the sound when I turn. I jacked up both sides and did the "wiggle" test but it didn't seem to move very much if at all. Could it still be the wheel hub or something else?

Most of the time, a hum or grinding sound in the front end can be traced back to a bad hub. Before you go that route, make sure you check the front brakes, if the pads are down to the wear indicators(noise makers if the truth be told), you can get a droning sound too.

Just had 2 new tires on the front and new brake pads. It still humms at highway speed. While the tires were off done the wiggle test on the hub and almost shook the car off the stand. They are solid, no wiggle. Tie rods seemed good too. Anything else this might be?

You can have a hub going bad that will pass the "wiggle test", when you get enough play in them so that they feel "loose", they are pretty well gone at that point.
There is a way to check for hub bearing noise with the vehicle running and the wheels turning, its done one side at a time, and its very dangerous if you don't know exactly what you're doing.(You can be killed or seriously injured, that goes for others nearby, so only trained techs should do this.)
Or the tech can use measuring tools with dial indicators to detect lateral and radial play that is undetectable by giving things a "wiggle".
You may want to go somewhere else and have it checked, also have the rear tires checked out for cupping or odd wear patterns.
Noise travels in vehicles and you can have a problem in the back that sounds like its right in front of you.

Mike, have you been spying on me!The other day my daughter was in town for a visit. Ask me to look at her Honda Civic that had a "wah wah "noise in the left front. After a test drive, I took it and jacked up the left front. I told her to "stand clear",started the car, put it in gear and very carefully eased off the brake until the left wheel was turning. Was a little leery of the right side trying to get traction.
Long story short, it was a bad tire and nobody got hurt by my little diagnosis procedure. But, as Mike said, doing this can be very dangerous!
Took her to the store the next day and got that tire replaced.
(Sorry to highjack this thread a little)
