Outer Limits 4x4 Board

hey guys
recently pick up my first 4wd
1989 soft top sierra
i was 4wding on the weekend and i hit a tree
it didnt leave any visible damage
but now when i turn right hard it makes a clunking sound as if its scrubbing on the front right wheel
but it hadnt done this before
any ideas what it could be
im thinking it mnight have pushed the (standard) front bar back towards the wheel
but it doesnt look like it
cheers

have a look for visable signs of where its rubbing, look for places where paint is worn off
