98 Yukon 4x4 auto. Front diff grinds loudly in 4. Swapped fluid for fun, no change.
Bought a front diff off marketplace. Told him the GT4 RPO code and that it’s 4x4 auto buttons.
Got to looking at it (new to me diff) and it’s got two plugs. One to the actuator itself. And one to the base of it where it connects to the diff. It’s from an unknown gmt400. I thought since he asked the right questions about gearing and auto 4 I would be on the right part.
Mine (the Yukon) has a single plug going to the actuator. 5 slot 4 pins.
I started with the sticky thread but it’s 85 pages!
I understand that something will have to swap. I’m hoping it’s the wires, plug or actuator. Not the axle ends since mine leak and probably killed my diff. Among other leaks.
Any help is appreciated. First two pics are mine. Second two are the new one.
