2005 GMC Yukon Q&A

2005 GMC Yukon Question: major service requirements at 105,000 miles. Front/rearl differentials?

I am trying to determine what is required. My truck has had all timely oil changes etc. Does it need new front/rear differential? Transfer case? fluid flushing? what is exactly needed -
Answer 1
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. -
Comment 1
thank you, do you also suggest this to be done every 50-60k miles? -
Comment 2
If you do this make sure the correct type lubes are put back along with any additives required! -
