Question Clicking and humming sound from front end?

I have a 2006 Touring. I have a couple of sounds going on.
1. When I make a hard left turn there is a clicking sound coming from the drivers side front wheel.
I was thinking ball joint but I am not sure.

2. When I am getting up to speed or slowing down to a stop there is a kind of humming sound.
Its like the sound a 4x4 with big tires makes when it is coming to a stop. I originally thought it was the sound
of my 18" low profile tires when I first got them, but after 3,000 miles the sound is still there.
Could this be hub bearings?
If it is hub bearings, how hard are they to replace? I am decent mechanically (from my Mustang days) but havent dealt with a front wheel drive before.
Would I need special tools? Is there anywhere I can find instructions on how to replace hub bearings?

Thank you for any help

Regarding the clicking noise, double check your CVC joints. Make sure the rubber sleeves around them are not torn. I had another front wheel drive vehicle that made similar sounds until the CVC joints failed.

Thank you, and that makes sense because when I put lowering springs on I had a problem with the boot on that side.

+1 on the possibility of a bad CV joint.A bad tire will cause a similar condition.
Changing the wheel bearings can be a problem as the bearing presses into the steering knuckle.If you have access to a press the job is doable.Replace the hubs at the same time.

Ok finally an update: I replaced the cv axle, and the clicking went away. However the humming remains and has gotten a bit louder recently (maybe just my imagination). Could the humming/drone/huge truck tire sound be anything but hub bearings? How can I tell for sure?

Does the humming getting louder when you turn one way or the other? Replacing the bearings isn't all that difficult. Remove the steering knuckle and take it somewhere to press the old bearing out and the new one in (usually runs $20/knuckle). While you're in there, I would check the control arm bushings and replace as necessary. If you change the bushings, get the car aligned afterwards.
