I hate weird noises lol

[cheeseraid]

Whats up guys! I'm new to the bored but Phil said I should get on here and join in the fun. I got a problem with my 190e, more of a weird noise like an exhaust pipe rattling but its not. I can't remember exactly when it started doing it but I've been trying to figure it out for awhile. The noise happens at 2 grand on the tach sometimes but not all the times. Sometimes when its really cold I get a whirling noise as well at all rpms. The rattling noise Is coming from the center of the car, the whirling noise I can't determine where thats coming from. The motor mounts have been changed, along with the tranny mount, center mount on the driveshaft (what I originally thought it was), and front flexplate. The back flexplate is still good. Last time I was under it, I didn't really check the tranny mount but Phil thought it could be that. I changed it earlier this year but I know by now that dosen't mean a thing. I wanna check that today but its 20 freakin degrees outside. The rear subframe mounts are sitting off the stops. The have alittle dry rot but hell its 17 years old. My little bro said don't worry about it man, it's old. You should here my truck, I laughed for a minute then said this is a Merecedes not a Chevy lol. Anybody got a idea on what else I can check? I checked the rear 5 link and it looks good (little dry rot again). The left side of the car on the rear sag's about an 1/8 inch. Maybe I'm missing something, I'm confused cause everything looks good and It dosent make one noise going over bumps Any help would be appreciated.
