F1502012

First off, I am new to this site so nice to meet everyone..

I had a buddy install a 2.5" Rough Country leveling kit on my 2012 fx4. After about a week I noticed how there was a shake once I got up to a decent speed on a highway, which is smooth. I took it to get aligned at a vehicle alignment place, and they said the alignment was really out of wack, but everything else looked fine. I was hoping this would change the shaking problem, but it never did. There still is a decent vibration when driving.. Any suggestions as to what I should do? I've been told that it may be mud up in there, and that the undercarriage needs to be sprayed..Right now I have the stock rims n tires on it..the rims are 20", not sure on tires as of now.

if there is mud on the wheels that could cause it

Go make sure everything is tight after the install (all bolts torqued back snug).
I mean if you put the same wheels and tires back on I would count those out. And you could see the mud if that was the problem

What about drive train angle?
