rubbing noise when i turn wheel to the right at crawl speeds
 

so if im backing out of a driveway and begin to turn my steering wheel to the right, it will make a rubbing noise but now the whole way turning. Example: Im slowly turning the wheel to the right and as im turning it, ... turn..... RUB......turn....... RUB.... and it ONLY happens when i turn to the right... any ideas,

What year Disco, what size tire, how many miles on it and is it lifted, all these things matter.

Go jump under your truck with wheels at full turn and see if you can see where they are or would possibly make contact with anything in the wheel well.

99 DISCO II, STOCK EVERYTHING, 120k miles

So, as already mentioned, crawl under your truck and look at the front radius arms for tire wear.
