no oil
The guy in the trunk is still alive!!!
There are a number of causes for a rattling noise that occurs in a car. These include low oil and an engine that is faulty or going out.
Possibly a loose heat shield or other component.
Certain types of tires may cause a brief humming noise after your initial acceleration. The transmission may also cause a brief humming noise.
The rattling noise is in there so you can move the head around.
Could be a loose or worn strut or strut mount
wheel bearing?
If it's a "chirping" noise, then you don't have the belt tight enough.
The noise can be comming from the weather stripping around the door, the wind passing past the antenna or from the wind around the luggage rack on acceleration.
It may be the heat shields on the exhaust system vibrating.
I had a similar problem with my 96 classic. I took it to a couple of different mechanics and none of them found a real mechanical issue with it. But one of them did tell me that as these jeep engines age they need better fuel or else they make noise. So he recommended that i use a higher grade octane. It seemed to fix the problem. As gas prices rose i would only use the high grade every now and then, the grinding noise on acceleration still happened but not nearly as frequent.
The rattling sound in the front of a 1995 Honda Civic wheels can be caused by wheel bearings. These bearing allow the wheel to turn and when they fail the produce a loud noise.
