ive been trying to figure this noise out since june. its a 4.0 2000 XJ. if you need me to put more videos up just ask me and i will.

i just really need help figuring it out.

 

i cant really hear it but isnt it quite obviously the tranny based on the fact that it does it while in gear but not while in neutral?

 

hm it was pretty loud on my phone. but see thats what i think. but i people have been telling me different things.should i see if there is any fluids in it?

 

OF COURSE. Or just replace the trans and check the fluid then

 

that would be a good idea..

 

just checked and they're not low

 

did you check it in park with the engine running?

 

just a guess but you can take a look at your motor and transmission mounts.

 

I would put my money on exhaust rattling against crossmember
My ex sounded the exact same when it did it
A new tranny mount lifted it off of it

 

OP needs to give his/her Jeep a good dose of "noggin pokin".

 

yes i checked it running and in park. no i havent check my motor or trans mounts. ill probably check that tomorrow. And thats another thing. i have this massive exhaust leak...or should i say BIG GAPING HOLE at the end of my cat. and its rattling pretty hard. the reason i dont think its my trans (im not saying im right) is because it shifts gears just fine. even when rattling.

i was actually planning on getting a new exhaust system soon because mine is all rusty (being from michigan)

Heres some pictures i just took

 

I'm having the same issue. Were you able to resolve the issue?
Thanks!

 

Dude chock tires, e brakes on get someone to put it in gear while you look and listen. But to me his sounds like mounts or hanger issues...or little of both. Also old thread and he has not posted since 2013 sohe may night be around here anymore.

 

Thanks for the reply
Did that.
From my post today.

The noise is only present when moving
The noise seems rotational in nature and gets louder with speed
The sound seems to come from the front of the transmission hump or back of the engine compartment while driving
Sounds like gearing rattle or rough bearing to me. Could be a dragging (like a stretched TC chain rubbing the housing) sound but tough to tell. Not a popping, hum, howl, or tic noise
No noise at speed with rear raised up
Differential, Transmission, and xfer case fluids are good
In Park at 2K rpm no noise and engine sounds good
Foot on brake and give gas, no noise
Put in Neutral while driving, rpm’s drop but no change in sound
No shifting issues when driving on the road
Putting in 4WD no issues
With the jeep on stands and indicating 40 mph (wife at the wheel), I was not able to pinpoint the noise (engine, trans, TC) using a section of garden hose. Nope – didn’t get under it. I was already spooked enough. However, the noise could be clearly heard when sitting in the Jeep
Just did the brakes and no wobble in the wheels
No extra noise going around turns so probably not a wheel bearing
Front wheel ujoints are fairly new
Front and rear shaft ujoints are new
Problem existed before the following as well
New motor mounts
New trans mount
New exhaust system to include replacing the cracked header.
