I have a '79 CJ7 and was wondering if for example I enable 4wd and lock my hubs for driving on snow, if/when I get to an area that has been cleared I disengage the 4wd but should I also unlock the hubs if I'm going to re-engaging it again soon?
If you are on the pavement you can run it in 4wd for short periods (say between snow patches). The YJ doesn't have a centre diff such as Landrover 90/discoveries which is why they can have permanent 4wd. If left in 4wd you would damage drive train due to "unreleased" torque between fore and aft wind-up. As long as you don't a locker in the front you are a'reit (as they say here) with hub locked as the previuous poster said
93 YJ with upgrades (and it is <font color=blue>Blue!</font color=blue>)
