2005 GMC Yukon Q&A
2005 GMC Yukon Question: major service requirements at 105,000 miles. Front/rearl differentials?
At 100k I flush all fluids of a vehicle.Some manufacturers suggest it a different intervals,but those intervals are put in place by pencil pushing engineers that have never had grease under their nails.It never hurts to change fluids. - bmdouble
