>4H - front wheels straight ahead only - why? was created by guttercat

Hello all,

Not a problem, just a question.

The handbook quotes "Do not shift between "2H" & "4H" unless the front wheels are in the straight-ahead position." Even when the vehicle is stationary.

I have a basic understanding of the Jimny 4WD system - the lack of central differential - and resulting transmission wind-up.
But can anbody explain why the front wheels need to be in the straight ahead position when you switch from 2H to 4H? This bit I don't understand.

Many thanks

They are hoping that front and rear wheels are moving at the same speed to minimise the number of pieces that snap off when the front axle suddenly spins up to the same speed as the back.

Could also cause a stability problem if you are in the middle of a bend I suppose

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there
