Vibration issues

Hi all KK Owners,

About two weeks ago I put my KK 2011 to good use and passed with flying colors.

However, while driving around I hit a small tree stump bending the sub frame (driver side) which is now replaced with a brand new one.

Since this and while driving at the same speed on smooth road highway I can feel the front passengers side wheel vibrate which is flowing into the steering wheel. The vibration gets loud for about 3-4 seconds, goes away for 3-4 sec, then loud for 3-4 sec and so on it's like the wheel is out of balance, but

I have a friend who is a qualified mechanic with his own work shop and not even he can work it out.

These are the things we have tried,
We have put brand new Cooper A/T3 All-Terrain tires, which are balanced and aligned after the sub frame was repair.
We have rotated the tires.
We have removed the rear drive shaft, test driven and still there.
Done an inspection on the CV joint, ball joints all good.
We have checked the bearings, by hoisting it up spinning the wheels and giving them a shake and there is no noise there, which has been confirmed by a second mechanic.
We have checked the drive shaft for any missing weights, they are all still there.

Next week we are going to hook up some microphones to the under body and see if we can pin point the problem.

If you can suggest anything that might cause this type noise it would help.

So the vibrating is regardless of tire position after rotating the tires?

Have you checked the inboard side of the rims to see if mud/tree stump/debris isn't stuck in them?

Sway bar and/or sway links intact?

Have you gotten an alignment since?

The alignment was done after the sub frame repair, we have not looked at the sway bar or link. That's another thing on the list.

We did not think about any mud or sticks in the guards, that's one thing I will be doing.

Thanks for your help, we are trying to eliminate so many different things at the moment and any extra things on the list will help.

I have similar problems with my 2010 but never hit anything. Dealer replaced both drive shafts under warranty. I aligned and balanced new tires. Still there.
