Hey guys. My sierra is starting to make a whining noise under Meath. It's related to wheel speed but is louder when you load it up. I put it on the hoist and drove it to 80km and noise was there but faint. Any ideas?

When I first got my sierra it was whining pretty bad and turned out to be the transfer case. Loudest in 4th and 5th gear.
When I would back off accelerator would almost stop whining and I noticed that the transfer stick was vibrating when the whine would kick in and stop when let off accelerator.
When I got transfer reduction gears and bearing kit it fixed it

I cant remember exactly have a look at lowrange offroad. Depending on what ratio but should be around 700 shipped

Would you recommend putting a 1 Litre case instead?
