Naw. We're just a couple of guys who can see the humour in things, regardless of "weather".

Well, the new rack is in my trunk and I'm going to install it tonight. I don't think the motor mount is to blame for the noise. The good news is the the rack came with every single part in the diagram above so it was a pretty good deal I guess.

I'm an awesome mechanic (sarcasm). The new rack feels slightly better to my hands but the noise in the wheel is still there. I'm going to replace my wheel bearing next.
.... more to come.

Im with viper on this one. mount first, then hub. If the hub is showing no signs of failure, and youve already removed a chunk of rubber, then you atleast you have evidence that peice is bad.
The scientific method will never fail. evar.

After you drive your car and it makes that noise, you may want to compare the temperature of the hub area of each wheel. If one of your hubs is noticeably hotter than the other, then you likely have a bad bearing. You should pop your center caps off your wheels, take it for a drive, and feel the heat coming from the spindle nut area.
It's hard to diagnose a bad bearing without a load on it unless it is really messed up. But a noisy bearing will generate heat.

Word up folks. I'm holding off on the knukle/ bearing right now and I'm going to replace my engine mounts tonight. I KNOW that at least the passenger side mount is tore up (from the floor up) so I can't make a mistake by replacing those.
I've actually done a hub temp check with my hand and even though it's highly calibrated, I couldn't detect a temp diff left to right. If I had been thinking clearer (so hard to do when my baby is crying) I could have put my pyrometer on it. It's a probe type though so it may not be the best for this situation.
To consistantly and instantly make the noise occur, all I have to do is turn left sharply like in a parking lot and give it a little gas.
Engine mount or wheel bearing.... that is the question. The truth is out there.

You HAVE to give it gas? Wheel bearing will make noise if you're even coasting through a corner with enough speed.
I think your idea of replacing the parts you know are bad is good. Can't really get a baseline if you have known bad parts.

You knew a big piece of the motor mount came apart and yet, you put in a newer steering rack. ?????????????????
