What can be done? I had AT's on 8 inch wheels and had some shimmy now I have MT's and 9 inch wide wheels and it is a little worse. I have read that some have fixed this with steering stabalizers who recommends them to fix the problem with first hand knowledge?

 

I haven't mounted my steering stabilizers yet but I am 100% confident that it'll fix my shimmy. Its worth a shot.

 

I had 35" BFG AT's on my blazer and had the same problem. I added a dual shock stabilizer and it made it a million times better. That should be the cure to your problems.
