I've narrowed down my problem to 2 culprits: either a bad front wheel bearing or warped rotor(s), but I can't seem to narrow it down any further. Here's my dilemma:

Why I think it might be the front wheel bearing:
-Back in August, I accidentally ran over what felt like a brick in the road. It busted a hole in the sidewall of the tire and bent the lip of the wheel, rendering it useless because it wouldn't hold air anymore. I ordered a used evo8 wheel and bought another tire, and had an alignment done, but the inside of that particular tire is wearing much faster than the rest of them. Toe is set to zero, and there is barely any negative camber (if any) anywhere on the car. We won't get into why I don't have any negative camber yet. I will be doing the next alignment myself, and not some ignorant redneck at any given local tire shop here. Also, I've also done the bearing test where you get that tire off the ground and try to wiggle it to check for free play. It feels just as solid as the rest of them, so I don't know .

Why I think it might be a warped rotor:
-I'm still on the original rotors. 113k miles on them, and they haven't been turned not once. About a month ago, I started getting vibration while braking. It doesn't happen that much while driving/stopping normally in town, but when I occasionally have to slow down abruptly or while driving at higher speeds on the interstate it's more noticeable. Obviously, the faster I am going when I have to brake, the worse the vibration.

Please read what I have written and take EVERYTHING into consideration before telling me what you think. Thanks for your input

 

C'mon people, if you have an idea of which one you think it might be and a reason why, please chime in.

 

In my experience, a bad wheel bearing announces itself as a noise, not a vibration. It is kind of a whirring noise, and typically is worse turning in one direction than the other (the bad bearing gets noisier when it is loaded more), which helps locate which side of the car its on.

If its just vibration, without a noise, it could be a lot of different things including the various bushings in the suspension getting old and worn out. Uneven wear suggests an alignment problem. Worn bushings could cause this even with a proper alignment.

 

There is a noise, nothing loud though, but it's probably just tire noise. I'll get underneath the car with a light and inspect the bushings closely.

 

Bring a pry bar while you're at it and don't be shy to poke around every single bushing. There should only be compression movement and that's it. Any real play whatsoever between bushing and metal parts warrants a replacement. Check your CV boots for leaks while you're steering rack is unlocked, have a buddy turn the wheel left and right as you poke about from under.
