4x4 Proper monthly maintenance

Lots of good information on here

AWD is for everyday use and cannot be turned off. Light duty use. 4x4 can be turned off and uses heavier duty components.

 

I seldom read manuals, so I never thought about the 4x4 lubrication. This is a wake up call. Love reading the threads!

The last time I used the 4hi and 4lo was at 20K miles. I've been working a lot more in a desk, so now it's 55K and has not stepped on dirt since.

If I use it in 4x4 now, what will I expect?

Also, my wife has Hummer H3. It's a full time 4WD. Should I engage the 4hi and 4lo sometimes too?

 

The differentials on the H3 will be lubricated constantly so I don't see that being an issue.

 

Good to know.

I guess I'll start engaging 4x4 of my '05 taco when I get out from this desk. I'll do it now!

 

Awsome website. Those classes look really interesting!
