So I got myself a humming at all speeds and I don't know where it's coming from. I got a 2000 XJ sport 4.0L 4WD with HD leaf packs in the rear, front axle swap to a HP dana 30 with 3.55 gears off a 1997. teraflex 2" BB and an OME tcase drop for 2-2.5 inch lifts. I just put +2 skyjacker shocks in the front but not the rear yet. The noise gets progressively louder as I accelerate but gets quiet quickly when I let off the gas. I can relate it to hearing my gears spin because as I go down in speed the noise level and tone goes down too. I got some low tread hancook HT tires on there and one of them is beat up from the accident I had in december. It drives, but I don't want to ignore this humming until it becomes a bigger issue. I have already pulled the front shaft and it's not that. The tires are balanced (even the one tire that's kind of shredded) The Ujoints were just changed a couple months ago. I'm thinking it's a driveshaft issue or a gear issue somewhere. Does anyone have a clue? This XJ must be saved!
