Hey guys my HDJ81 is howling and has a slight vibration under the driver side (RHD) from the front end, it happens at 80kph when it has light throttle.
I removed the front drive shaft and the noise went away. i just did the u-joints and cv on the front drive shaft and also got it balanced so i don't think its the shaft.
the noise changes slightly when i engage the center diff lock and the front shaft is in, but still seems to be present, just less noticeable.
also when going on and off the throttle quickly theres a clunking noise which is not present when the front drive shaft is removed. I'm thinking its something to do with the front or center diff, is there a good way to find out which one? there were no large metal shards on either drain plug.
the truck is a:
1990 HDJ81 2.5 OME lift triple locked 31'' tires
