Rattling sound in an '89

My '89 YJ started making a rattling sound when coasting. It just sounds like something small is loose. Before I hunt for it would anyone be able to lead me in a direction?

I have an issue similar, except mine is worse when I accelerate. I couldn't find anything lose, and even just had it at a shop. It was there for 17 days.They thought it may be the rear main bearing on the engine, but they ended up tearing most of the engine down checking everything and did not find anything. They said that a rock or something may have gotten in somewhere and it rattling around.

Soft top? I had a rattling sound for a few days, went to take the top off and found 5 of the 6 screws holding the windshield channel on were stripped out. Replaced with bigger screws, problem solved.

My ebrake bracket system was broken and caused an awful amount of rattling. Also some bullet casings got behind the dash after shooting and I had a hard time finding those

I'm gonna go with what juggalo586 said. I don't have a soft top so it's not that and it sounds like it's in the engine. It does actually sound like pebble or something bouncing around. But today it hasn't done it so idk what the hell it's doing

Will it rattle with the jeep stationary, in neutral, clutch released? Can you feel it through the shifter?

It's an automatic so there's no shifter or clutch. But it doesn't happen when idling sometimes when I'm stopped at a light though.

U-joints do make noises either when letting off the gas or getting on it.

Alright so it sounds like it's a normal thing right?

No. You need to put it up on jack stands and check the joints for play, rust coming out, etc.if they have rust powder coming from the caps, they are toast. If all is tight , grease them. See if the noise goes away.

Noise

As you said earlier that the noise sometimes does happen at a light, then it will not be the u-joint. I am curious though, what would happen if you have the vehicle making noise you put it in neutral and let it coast and maybe turn off the engine (do not lock the column) and coast in order to pin it down a little more closely. Noises can come from everything from heating manifold, cat converter, exhaust, bearings etc. Need to pin it down to you can make it happen, then get as close as you can to get to the area concerned.

I was just looking underneath it before and saw that one of the heat shields were loose with a missing bolt. I have a feeling that could be it

So the rattling has gotten worse and will be taking it to a mechanic. It's progressed to loud metallic rattling in the engine area and happens when it's accelerating up hill
