I've been scouring forums and finding a lot of conflicting information on this topic. I wanted to see if anyone here had first hand experience or more knowledge on this.
I have an 03 LE with the Allmode 4WD (electronic dial). Many sources say that this 4WD system isn't compatible with manual locking hubs because the front driveshaft drives an oil pump. If you disconnect the front hubs than the oil pump disengages and you could have overheating issues.
Some users who have done this have 4WD lights and errors after highway driving and others don't. Some claim that this could cause harm and overheating issues, but I can't seem to find any concrete information on this.
I understand there could be issues if I engaged 4WD with the hubs unlocked; I'd obviously make sure they are locked before changing. I'm still nervous this could cause issues to the Allmode 4WD system. Since my girlfriend drives the Pathfinder most of the time, I don't want her freaking out everytime a 4WD light comes on.
The motivation for this is to increase mileage. Since my girlfriend does 15k highway miles a year, this could help in the long haul. Any feedback on your mileage for those who switched would also help.
Does anyone here have first hand experience or have some detailed info they can share?
