hi there i have a 05 rubicon with a 6 speed 37k miles on it.
it's got a RE 4.5 LA kit tom woods driveshaft rear and a new front driveshaft put in last yr. i've greased all the u joints, ball joints everytime i go thru water. The drivetrain just started making noise loudest when i'm decellerating I took it into aamco they said it was the tranny, i replaced it with a new one and had em replace the throw out bearing pilot bearing and put in a new centerforce dual friction clutch. I have also checked and replaced the transfer case ATF+4 fluid no metal in it when i drained it and i checked the diffs for water in the oil they were fine no metal i even replaced the fluid in the rear and added the limited slip stuff. The noise sounds kinda like a rubbing sound i looked under the jeep the driveshafts don't look like there hitting anything. I got the jeep back from aamco and it's making the same noise any ideas wft it is this is driving me nuts i probally got the new tranny for nothing. It makes the noise in every gear and stops as soon as i push the clutch in.
