    Only when accelerating? How many miles does this car have on it? When accelerating hard, slow, uphill, etc? Does the rattling sound come from middle of the car, behind, up front, left, right, all around? Sorry for the barrage of questions, but this one could go in a lot of ways, try and give me all the details possible.

Hello Lisa,
Rattles are always a fun thing to chase after. The first thing that comes to mind with a rattle under acceleration would be a heat sheild. Over time, heat shields which protect the under body of the car from exhaust heat come loose. Might want to have an exhaust shop take a look at it for you. I have heard of weak tack welds located on the heat sheilds by the catalytic converter. So you can ask an exhaust shop to take a look.

Although if you are one to get down under the car and a bit dirty check it out on your own. You might be able to check without putting the truck on a jack stands or a lift. Basically you will want to ensure the car is cold. If the car has not sit for a little while, I would not recommend touching the exhaust. YOU WILL get burned. :) Once your sure its cold and want to squeeze under the truck you can follow the exhaust tips all the way up to the catalytic converters. See pic below(number 16 is the heat shield). You will see the tin around them and be able to shake them a bit. If you hear your rattle there is your problem. If not check out the other heat shields.

2005 Nissan Altima makes rattling/vibration noise


It is possible that you have some timing chain noise, especially if you have the 3.5L engine. The secondary timing chain tensioners on the 3.5 have a known problem, Nissan has issued a service bulletin regarding this and there is an updated part to replace them. It is not a cheap job, but your dealer may give you some "goodwill" depending on your mileage. If you have the 2.5L the problem may a couple of other things...even more serious! They had catalytic converters that came apart and got ingested into the engine, eventually destroying it. Try googling "Altima rattle" and include your engine size in the search. There is a ton of info on the net about noises in these cars.

Noises in my 99 ford taurus


My first thought is to have the Catalytic converter inspected. Many time the converters will have the insides break away and begin to float around, the insides of the converters look like a honey comb and after the engine is good and hot the dislodged piece will adhere to the other parts of the honey comb thus making the rattle go away.
