Update
well finally found problem, first of all noise wasn't coming from the front. We got it up on jack stands and it was coming from the rear, sounded like wheel bearings so we replaced them, wasn't them either, it was my pinion bearings, they were pitted and scarred really bad, we found a piece of a bearing cage in the differential, but none of the bearings were missing anything, so someone must have changed some in there before and didn't get all the metal out and it got into the inner and outer bearings, we changed them and its quiet as can be
