Manual Hubs question

I have a friend who's had Jeeps for a long time. He told me that, if you drive around town a lot, to engage your front hubs one day a month (not engage 4X4, just the hubs) to keep everything in the front axle lubed up and trouble free.

Has anyone else heard this advice before? Is this true?

I do that also. Once a month, I lock the hubs and drive to work (20 Miles), then I unlock the hubs.

I'd heard that most Ford 4wd failures are caused by never lubricating the parts by making them rotate.

I do the same thing. Put 20-30 miles per month on the van in 4wd just to keep everything (hopefully) working properly. This was recommended in my Toyota's owners manual, so I assumed same would be true for the SMB.

Sure, if it is on dirt roads or soft surfaces. Never drive on pavement with locked hubs. Axles can snap. Don't you hear the chirping as you turn. That's from one tire rotating at a different speed than the other, both connected with a solid axle. Not good.

That solid axle has a differential, so it's OK to drive on pavement with the hubs locked -- if your transfer case in in 2WD.

You're right, Jeff, Being in 2wd is the answer.
