OK here goes another possibly dumb question!

I have not used the 4x4 since I got the truck in Aug. It's in the garage at the moment.

On my 63 4x4 burb do I need to lock the front hubs before I engage the 4 wheel drive or can I engage " on the fly" for non low range 4x4? My wifes tracker 4x4 is a 4 wheel on the fly but you must be stationary to engage the 4x4 low range.

Can one of you guys run by me how the 4x4 works in my burb?

Thanks....EB.
