Why doesn't my 4-wheel drive engage?
I have a 1992 Toyota pickup SR5 with the 3.0 engine and the 4 wheel drive does not engage when I go to manually put it into 4-low or 4-high. It DOES NOT have manual hubs so as far as I know it uses vacuum to lock the front hubs in. Is there any fix on to be able to use the 4-wheel drive?
Is this a good question?
