ok took my 37's off and put the stockers on for a road trip. I have a wierd noise that sounds like driveline or a bearing issue. No noise until i hit 55 or 60. i initially thot it was just a tire issue but after 400 miles last night it didnt go away--it got worse...any ideas? u joints all SEEM to be tight. i just drove it this morning and the noise is not as bad. i do still have the 6 inch lift installed and i have a carrier bearing shim kit installed. truck has 47,000 miles.
