Remember they lived in the red mts (i think) and the lords in the red mts may think diffrent about khuzdul then the other dwarf lords in middle earth.

Petty-dwarves differed from normal Dwarves in various ways: they were smaller, far more unsociable, and they freely gave away their names: other Dwarves kept their Khuzdul names and language a secret. This may have been one of the reasons they were exiled. Tolkiengateway: "This may have been one of the reasons they were exiled."

LOTR-wikia: "had been exiled for reasons unknown"

So you can't say it was this reason. But the petty dwarves didn't live (only) in the reds. Hurin met them in Beleriand, far away from the reds. I think they didn't have any important settlements and mostly wandered around.
