Hi all
Just a quicky, with older vehicles or troopcarriers, can you go running about with the front manual hubs locked in but the 4WD selector lever (or in my case for Hi4 selector switch) unlocked and thus no engine output to the front diff? Or should you only engage manual hubs when in some form or other of 4WD?

I have a 1997 Holden Jackaroo with manual locking hubs. The owners manual says to lock the hubs and not engage 4WD and drive the vehicle for at least 20km every month. The reason being that rotating the front axles periodically like this prevents the lubricating oil and grease from becoming congealed.
I have had the habit for many years of engaging the hubs on days when I KNOW I will need 4WD, and disengaging them at the end of the day. I have had no problems with that and a lot of 4WD in 120,000km.
P.S. Keep checking that some feral hasn't locked ONE hub leaving the other free, when your vehicle has been parked somewhere (they do that).

It is fine.. All you are doing is making the front diff and drive shaft turn which turns the oil and greases which is good....
But it should use a little more fuel .... Whether or not you could measure it is another matter....
I kept
mine (gq) locked in all the way along the OTL and only selected the transfer case accasionally....._____________________________________________
