well i think i might have an idea what might me causing the whirling noise, do you think 85-140 gear oil would cause it? I just changed it like 2 weeks ago, don't remember it pre hand. The other noise I still can't figure it out. The noise will continue till you let off the gas pedal, push the gas pedal again when its around 2k it will do it again. I don't know much about the tranny and torque converter systems on these cars but would you think I'm starting to have a problem there? The fluid is clean though unless the tail shaft is having a problem. Sometimes when the car goes in first (mercedes second lol) it clunks from the rear end. Though when I get under the car and try to reproduce that noise, no matter how hard I turn that drive shaft it won't do it. I think what started all this is my damn 18's. E430 17's coming soon. I'm just throwin straws to the wind right now, anybody have a similar problem or noted problem like this? Maybe had noise problems with 18's, I mean these wheels weigh 48lbs. 1991 190e 2.6 somebody has had to have a similar problem before like this.
