Great more squeaking

[Jmoore]

I've been daily driving my 81 step side for quite some time now (didn't really have a choice as I went and bought a Porsche 944) and I've noticed a fairly quite whine at low rpms that goes away after about 2000 rpms, and a very noticeable squeal under hard acceleration say around 3500+ rpms. I have a feeling that the low rpm squeal is a pilot bearing issue, but what could the high rpm squeal be?

Any help is welcomed
