4 Answers


What is the difference between being in 4WD high or low and being in 4 wheel? I don't think there is any such thing as 4 wheel that is not high or low.

It is a all time 4 wheel drive vehicle there are three setting 4wheel, 4wheel high lock, 4wheel low lock


I suspect your center differential is locked when it should be open.

Ok thank you
