Hi folks, new to this forum. Hope to meet some friendly, and helpful people
Anyway, I have an 05 GMC Sierra (1500/5.3/Z71). It has 36,000 miles (I bought it new). I have a company issued vehicle for work so I (unfortunately) don't get to drive my tuck much....
I have been through hell with the 4 wheel drive....a year ago I started having the famed "Service 4WD" on the dash. I took it straight to the dealership and they said it needed a new switch, so I had them do it ($400 thank you, they also said they had to re-program something as well).
Now, about a month ago I start having the "Service 4WD" message again. this time the truck starts some funny things.....shifting itself into 4-Lo/Hi....Not shifting into 4 at all......I take it back to the dealership, now it needs an "encoder motor", so I had them do it ($630 thank you).
And that brings me to this: I am now hearing some "moans & groans" from the transfer case when in 4 wheel. I am the only owner/driver. NOBODY drives this truck except for me. It has never been "4-wheeling, beat on, etc.). I always take it out of 4wheel on even partially dry roads (I mostly use the 4WD in the winter, I live in New England). Anyway, I am going to try flushing the transfer case, but I dont want to open a can of worms here. I also dont want to keep shoving $$$ into this truck if it is going to keep this stuff up
