Wow bimmerdude - great call. Thanks for your post.

After a good scrubin' down and cleaning everything, I started to dig into my rotational squeaks.

I switched from my winter rims (17" with very low pressure due to laziness :p) and put on the 18"s with correct pressure. With the new rims on, the sound only happened intermittently. I found that if I lean on the e-brake handle the noise goes away. With my winter rims the noise happened all the time and louder so its was harder to figure out.

I could of swore to anyone that the sound was coming from the front of the vehicle, but whata know. I haven't fixed it quite yet, but at least I know what the issue is.

Thanks again guys
