Some make it a long time before they crack. Mine lasted until last spring when I ran down and extremely washboarded road on a really hot day. It cracked by the airbag corner. I have since replaced it.All the other Tahoes and Yukons I looks at had cracks. Some worse than others. This one was overall in much better shape all together. Nearly looks brand new.
