I was told it was the gear box by the dealer but then I posted something about it on here and was told the 1500's don't have a gear box. But I guess steering gear is different then gear box. Anywho mines been replaced twice, the second time they didn't want to since it had already been replaced but the noise got worse. They actually jumped in a newer one on the lot and heard the same noise, they said its due to bigger tires. Well finally a third time to the dealer they replaced it, apparently the first manufacturer of the parts weren't very good so they changed manufacturers. So far no issues on the new on and it's been about a month since then.
