#1 of 2 Knocking Sound on a 2002 GMC Yukon by bigwick Aug 12, 2008 (4:57 pm)
I recently purchased a 2002 GMC Yukon. When i first start it in the morning it knocks for about 20-30 sec; then runs fine. I ask the dealership about this and they said that is common on the Yukons. Does anyone elses do this? Have you tried to have it fixed? Replies to this message: jarhead0341 (Sep 18, 2008 7:42 pm)
