Front noise please help........

[Tito_146]

Hi there guys and girls. Hope any of you give me an idea of whats going on. I have a 4x4 96 xlt and have a terrible noise (whaaammm whaaammmm whaaammm) coming from the front end. I try to remedy this by rotating the tires with no results. Then I notice a small leak on my front diff right where the shatf couples to the diff, I replaced the seal no leaks but the sound is still there.

The sound increases with speed not engine speed. I already tested for that by getting my rig up to speed then shifting to neutral and the sound still there ruling out the possibility of a bad pulley or something like that on the engine. Plus something I think I should mention the fluid on the front diff looked really bad when drainned.

I've being doing searches, nothing I read so far is what I'm looking for. Any suggestion will be greatly appreciated. Thanks in advance.

There are so many things that could make a noise that it is hard to narrow it down by reading a description of the sound. If you cant figure it out and it gets to the point that you can't take it any more you might consider having someone look at it and diagnose the problem. They don't have to fix it, just diagnose it for you and then you'll know what to fix.
