Hello This is first time doing this hopefully I'm in the right section. Ok I have a 2000 jeep grand Cherokee limited, 4.7 quadra drive. I bought the vehicle a year ago overall it was in good shape except for a humming noise coming from the front. I thought it was the wheel hubs figure no problem, I can fix easily. Since I've had the vehicle by the way first jeep and I love it I've done a lot to it so far, I plan to post some pics soon. In the front I have replaced new, both wheel hubs, both CV axles, Had all bearing in the front differential replaced by professional and converted the front drive shaft repezzetta to a double cardin u-joint.
With all these changes still have the same noise. It starts at about 35-45 mph and gets louder the faster I go. when I let off the gas the sound goes away when I step on gas again it comes right back. when I have the cruise control on it will do the same, when cruise needs to slow down the noise goes away come back when it needs to speed up, like when going up and down hills.
Other than that if I can get this corrected this jeep will be perfect. I'm hoping I can have some help hear.
