Front spacers and now a vibrations

Ok before you all start in, yes I know spacers are not the best option for a front end lift but it's what I could afford. I do plan on changing them out with new coils and struts and UCA.

So I have a vidration or a grinding in the front end, it feels like it come front center but I only feel it at 40-45 mph. Feels like I'm driving over rumble strips on the highway. It's not consistence i feel the vibration every 2-4 seconds. As far as I can tell I have zero rubbing and I did install a diff drop to the rear. My angles to my tire don't seems to be that out of align. Anyone k ow what might be the problem ?

 

Needle Bearing in the front diff, get the ECGS bearing and change it up.

Might as well swap the suspension out while your in there.

 

Yeah I hope to get that done early fall. Just starting to look at options that will work well with my dakers
