small vibration question

When I bought my truck, it already had a leveling spacer lift on it, and a small set of vibes and noise around 30-40mph. I’ve dealt with it, since it’s only noticeable with the radio turned off, and vibrations in the pedals. The other day, I was driving around town, and on a straight road, going 35 I switched it into 4x4, and the vibes went away. Anyone else experience this? Almost makes me thing that my vibrations aren’t coming from the leveling kit, and from something up front being worn out, or loose. Anyone know about this? Good? Bad?

I will be adding 5100 and 885x springs in the springtime, I’d like to at least understand this issue, before I bring more issues into the equation if you know what I mean.

Sorry if this has been asked or addressed, I tried to search, but couldn’t find anything relating to my situation.

 

sounds like the front diff

Put "front end vibration" in the search field, and you will find more than plenty of related topics on this issue.
