Ok for about 2 years now I've been hearing this terrible squeak coming from what sounds like the front suspension. In fact, I'm pretty sure it's the front suspension.
It used to be only in cold weather and over large bumps in the road. Now it doesn't matter if it's hot or cold, and it is non-stop while I'm driving. It sounds like rabbits F***ing on an old bed. I can hear every time the spring expands or contracts a tiny bit. It is LOUD and embarassing. It sounds like the struts are about to fall apart.
Sounds like this except it's my front suspension: http://www.youtube.com/watch?v=XCFgc2WMDaA
I thought it would be the sway bar for sure, so I took the bushings off and saturated them with silicon grease then re-installed --- didn't work.
When I push up and down on the front of the car, I don't hear anything accept a very quiet click, nothing like the sound I hear while driving.
From 0-50mph, the sound is very noticeable. I can't hear anything when I'm running about 75mph on the interstate.
What could it be?

If it's my ball joints I'm going to be pissed. I've only put about 1500 miles on them.

A guy at Tire Kingdom told me that my strut mounts were bad, but I think they were just trying to sell me something I didn't need, since I was only there for an oil change. It doesn't sound like strut mounts does it? I'd think that would be more of a clunk sound.

Ckroush i have the same darn noise!
Mine is definetly comming from the front driver side.
It's at low speeds say 15~40. usualy when the car is cold.
Here the kicker it goes away imediately after you tap the breaks. as soon as you step off the breaks the noise comes back.
Now I was suspecting obviously something with the rotors or break pad wear sensors.
I just had at full front brake jobs including new rotors and pads and the @!$#%@% noise is still there!![Egads!](https://www.clublexus.com/forums/images/smilies/pat.gif)
Told the mechanic to check it again. They did found nothing wrong with the breaks on all 4 corners.![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)
Bearings?

I also had this problem.... What I did to fix it was:
Turn the wheel all the way right and jack up the car properly using jack stands etc. Get under the wheel and look for this metal cover that is behind the rotor... Hit the bottom of the wheel to see if the noise is coming from there and if it is, literally bend the metal backing (not to much) just push on it to shift the metal a little bit. Hit the bottom of the tire again, see if it still makes that noise.... Hopefully that helps! It did for me....

I'm thinking it's the top hat. I have the same problem as of now, but I haven't fixed it yet because I can live with it. It was very apparent when I drove in 20-30 degree weather, but as soon as it got hot, the problem went away.
Most of the time, if the noise varies with temperatures, its most likely rubber/urethane related. The colder the temperature, the harder the rubber gets (which is why summer performance tires are not ideal in snow, because they get too hard). If the top hat was truly the culprit, then it's getting old. Ever try to use an old pink rubber eraser? Due to age, it gets hard on the surface. Your rubber parts are no different.

I've PMed GSteg before about this problem and like he said on here, it might very well be the Rubber Top Hat. Is there any way to find out if this is indeed the problem without paying Lexus $60-$70 to tell me.
If it is the top hat or spring insulator, whatever, how much are we talking about? I assume we're looking at a good bit because there is so much labor involved.
I've also heard things about loose bolts on the subframe or subframe bushings. Possibility?

I was able to just bended out a little with a wooden stick through the opening in the RIM. No need to jack it up or anything!
Thanks JOE! and Thank You Clublexus!
