Trying to solve my 96' Cherokee 4.0L 4x4's highway rumbling that it's had for years.
Going over 65 brings it on, it sounds like bass, like a subwoofer. Gets louder with speed. Sounds like it's coming from somewhere in the front half of the Jeep maybe? It'll do it on jack stands with the rear wheels/drums off.
-New from dealer OEM motor/transmission mounts
-New wheel bearings
-New front axle bearings
-All new U-Joints for both driveshafts, from a driveline shop and both balanced there.
-Have replaced the rear axle since it started doing it.
-New output bearing in transfer case
-New tires
-New catalytic converter
-Have replaced transmission fluid and transfercase fluid.
Here's a video of it, nothing to see, only audio. Unfortunately there isn't a lot to hear if your speakers don't have bass. About 6 seconds in it downshifts (that's the engine sound). I speed up from 65-80 or 85 then back down to 65 in this video.
Has AW4 automatic. Can a bad flex plate do this? Transmission? It shifts great, bass does seem a little louder/harsher when accelerating but is not really RPM dependent, it's speed over 65.
Any help is appreciated.
