The OD button literally just pops out of there. Need a very small screwdriver or like that to pop it out. Pop in a new one if need be and you are set. I think there is a quick test with an ohmeter and thats about it. I have heard that a lot of guys like synthetic in the diffs.

If the switch checks out.......take the bottom half of the steering column off. There you will see the very fine wires that go up to the switch. Sometimes one of those wires gets broken.

I personally use Redline oils in my gearboxs. Great stuff. Also they are a sponsor here on this website.

Wires are cut off. Same happened to mine. Must pull shroud off from under the steering column and over. you'll fine three very thin wires going to the signal arm which are probably all broken off. repair and move wire to a less vlunerable route away from the tilt knuckle.
