The bump stops are metal and you're getting the the grinding noise from them. Real easy fix--just take your finger and dip it in all-purpose grease and then coat the face of each bump stop.

Just to clarify, he means "steering stops" and not bump stops. He is correct that a little grease on them will quiet them down.
