This appears to happen only when the truck is cold.
About 10 minutes after you get on the freeway
60 to 70 mph the front end starts to shake steering wheel also. The longer you drive at a steady speed the worse it gets. Step on the brakes it gets worse. Take your foot off the gas and let the truck slow down 20 to 30 mph the shake stops. Now when you speed up again to 60 mph or more the shake DOES NOT COME BACK. You can drive all day long at freeway speeds and no shake at all perfect ride. Park the truck for 4hrs or more and it all starts over again.
Got any ideas Please help if you can.
