Re: Drive to three wheels only ???
In an open differential when you turn one wheel by hand, the other side should turn opposite. When you drive both wheels with the engine and would hold one side still, the other side should turn with double the normal speed. But when the jeep is on ramps and you let the wheels spin by the engine, its not normal when one wheel stands still. This could eventually happen when one side would be heavy to rotate, but it was checked to be free. Independent which locker you would use, when they lock then both wheels will turn into the same direction. The e-locker functions as an open differential when not activated.
So knowing the normal operation of an open differential, it should not be normal that one wheel stands still when the other is driven by the engine. It could only happen when one wheel was forced to stand still, but then the other side would turn with twice the speed.
And when i´m not wrong, the e-locker was never used from the factory on the WJ. The WJ can have Trac-lock or Vari-lock, but both are mechanical/hydraulical units. Could be an aftermarket installation though.
I think that the WK started to use e-lockers, isn´t it?
