My summer tires make very little noise, and my winters make a TON. It's especially bad while turning at sharp angles.
Well, my summer tires were cupped on the inside edge so they were unbearably loud. But the whirwhir noise (which, coincidentally could have just been the cupping) was there and started around fall of 2012 (~40k miles?) which was before the tires got really bad.Did you start hearing the humming when you put your winter tires on? My snow tires defiantly make a sort of humming/whirring noise compared to my all seasons. Same with my all terrain vs. all seasons. Just the way the tire sounds with a particular tread pattern.
Will do.The wheel might not necessarily feel loose or have play if the bearing is bad. Jack up the car again and perhaps use a mechanics stethoscope to listen.
Well, I technically haven't pinpointed where the noise is coming from, so it could be from the front. I noticed the cupping while my tires were on the rear, but at least 2 of them were cupped and they're rotated all the time so I don't know which corner(s) caused the cupping. I don't think a bad CV would cause cupping, though the cupping and whirring noise might not even be related.There is no CV joint on the rear wheels, so that shouldn't be it. They make more of a clicking noise anyway. I wouldn't think 1/8th toe would cause an issue, next time you get an alignment, ask the tech to set it in the middle of the acceptable toe in/out range. I never did like how they don't center it in the middle of the range.
Not to insult your intelligence or anything, but you're running them at 35psi right? I used to use only pen gauges and cheap dial gauges, I ended up getting a nicer dial gauge only to find out those pen and cheap dial gauges are pretty much junk. They were off by 10% or more in PSI. This is what I ended up with and I'm very happy with it: http://www.amazon.com/Joes-Racing-32307-Pressure-Gauge/dp/B00404WDUC/ref=sr_1_3?ie=UTF8&qid=1386186884&sr=8-3&keywords=tire+pressure+gauge
Well, I'm guilty of using one of those pen gauges...Not to insult your intelligence or anything, but you're running them at 35psi right?

Milwaukee isn't really known for its smooth roads... As far as extra weight, definitely not. In fact, I've lost about 45 lbs since I purchased the car!I can't image why a bad CV joint would cause cupping. A bad shock though, yes, that could not provide enough damper causing the wheel to bounce and prematurely wear the outside of the tire. Are the roads bad where you typically drive?
You aren't carrying extra weight in the car, are you?
I want it. I need it.A tread depth gauge might also help you, I take measurements of the inner/center/outer tread when I rotate the tires every 6k miles. It may help you spot problems before they become too serious: http://www.amazon.com/Milton-S448-Tread-Depth-Gauge/dp/B0002STSQM/ref=pd_sim_auto_1
It's not your fault - there are a lot of variables here. The -2.2* camber is pretty much borderline out of spec. I'm thinking about getting adjustable camber arms soon.The humming could very well be coming from an out of spec camber. Sorry I can't be much more help. Good luck.
When you get your alignment, sit in the drivers seat while the tech does the adjustments. Include everything in the car, weight wise, that you typically drive around with. Especially on lighter cars like the Focus, it doesn't take much weight to change the way the suspension handles when loaded.PratoN; said:
Thanks, Todd! Will do. I'm planning on checking the front bearings again today since last weekend I didn't spin them as fast as I spun the rear tires when I started to hear the clicking. I just want to make sure the front are good too so that I don't have to make a second appointment if one (or both) of the front bearings is also bad. After all, I do have 80k miles, low profile tires, and I drive through this daily:Hey PratoN,
I do recommend making an appointment with your local Ford Dealer. Once you do so let me know and I'll look into available options.
Reading this thread has me worried. I've got the Ti handling package as well. I haven't noticed any of the noises you have, nor the weird tire wear issues. However I'm only about 12k into my tires and really I haven't looked that closely because everything seems fine and Discount Tire hasn't said anything when I've been in for rotations.I feel like I'm talking to myself, here...
Anyway, I've opened up a case with the regional service guy. I have also decided to take it to an independent shop for a "professional opinion/quote" so that I can use that as leverage against the dealership when I go the second time. If they still deny it, it's small claims court time. I'll keep you guys up to date! 
I'm sure it will! The worst case scenario is I replace them myself for $250 and don't get any reimbursement from the Ford dealership.I hope it ends well though.
