2006 GMC Yukon Q&A
2006 GMC Yukon Question: I hear a howelling noise coming from my truck while driving.
my rear diff is new and that is not where the noise is coming from. i hear a whirring or howelling noise under acceleration and decell also.I jacked the truck up and placed tranny in neutral and spun the rear wheels turning the driveshaft and herd a dry brushing/squeeking noise from transfer case/tranny aera. the trans shifts good and has clean fluid. the truck has 100k on the clock.can you help me diagnos the noise ? - fitzwell
YOU MAY HAVE A TRANSFER CASE ISSUE OR POSSIBLY A U JOINT PROBELM. SERVICE YOUR TRANSFER CASE A(DRAIN AND FILL) AND LOOK FOR METAL IN FLUID. AT 100K IS OVERDUE ANYWAY. - globalhelper
