sounds like the cv joints need replaced
I'd like to know too! Mine does the same thing - it makes a rattling noise upon startup that goes away after 30 seconds or so and isn't present while driving or idling.
i had a rattling noise in my 2000 ls, was told it was worn tensioners on timing chain. i guess they are made out of a poly carbon and wear after a while. haven't fixed problem yet...
Most likeyl cause could be a bad pulley
my guess is the lower motor mount
Can be a multitude of things. First see if its from inside the engine bay and occurs while in neutral reving the engine. From there check your headlight assembly.
for the noise it makes while in use
Nine times out of ten it is a worn serpentine belt. Tensioners are also know to make a rattling noise congruently. Changing your belt and/or tensioner should solve your problem.
If the AC compressor makes noise when turned on, it could indicate several issues, such as worn bearings, loose components, or refrigerant problems. A rattling or grinding noise often suggests mechanical wear, while a hissing sound could point to refrigerant leaks. It's essential to have a qualified technician inspect the unit to diagnose and address the problem promptly, as continued operation can lead to further damage. Regular maintenance can help prevent such issues from arising.
I don't think anyone can answer this for you without seeing and hearing the jeep. Listen to it while it's running and try to locate the noise. Be careful because the exhaust is hot and the fan will be moving while on
You might want to have the CV joints checked. When bearings start to go out, they make a "clicking" or "rattling" noise while driving - especially while making turns.

You probably have a bad bearing.
