New sounds after hub swap...thoughts please...
Hi all.
A local shop told me that my bearings were bad on the front of the GXP so I ordered a used set from a reputable vendor for our cars (low mileage pull outs.) Anyhow my factory rotors had a torx screw that fixed the rotor to the factory hubs. The new hubs weren't machined for the torx screw. I didn't figure this was a big deal because the lug nuts hold the rotor in place anyhow. Was I wrong about this?
After I changed the hubs, I've noticed that some aspects of the steering feel tighter, but I've picked up a rubbing "woop woop" sound that increases in frequency as speed increases. I'm also noticing some vibration that is transmitting through the steering wheel. I just pulled everything apart and put it all back together to check for anything that I might not have tightened, but I found nothing.
What do you all think? Any suggestions are GREATLY appreciated.
Thanks in advance,
BJ

Well, your wheels/tires didn't just magically go out of balance...so I'd look more closely at how you installed the wheel bearing.
Unless you know you lost a weight (from the wheel), or smacked a curb/pothole...or even went through an auto-carwash and knocked a weight off the wheel...your wheels/tires are likely no different than before.

Or his hub was bad enough that it was masking the tire problem. I've seen that more than once.

hub
The vibration seemed to be a bit worse today, so I'm going to a wheel/tire/suspension shop that I trust tomorrow morning. They have a lift and I'm going to see if we can figure it out quickly. I take pride in doing it myself, but I don't want to risk tearing something up. I'll let you all know what I find tomorrow. I don't think it's the tires, but it wouldn't be the first time I've been wrong about something.
Thanks,
BJ

well it's one of two things..
1) the tire/s is/are out of balance and/or cupped or otherwise screwed up.
2) the wheel is bent (a lot less likely to cause a noise, but it could cause the above-mentioned tire problem.
or
3) the hub you just put on is bad..
Ok, so that's 3 things But you get the point

a 'whoop whoop' is ususally the hub/bearing.
Go about 30mph (or fast enough to duplicate the noise) and steer hard to the right then left. If it gets louder one direction, and quieter in the other direction, you know it's a hub/bearing.

I'm an idiot...
Well, I found the answer today. I took it to a shop I use for some suspension work and they found that the noise I'm hearing is where I scuffed the rotor BEFORE I figured out that I needed to remove the torx screw.
Guess I get to pay the dumbass tax.
Thanks for all of your help,
