Loud bang when 4x4 is on

[Cregger]

I switched hubs right to left.

Then i first try 4x4 and low range on iced grass. Nothing happened.

Then i go rough san road with grass sides. 4x4 on started banging when i accelerated. When speed was about 20-25mph bang sound was changed to smoother and thicker. And when i slowed down thickersound begome thinner and bang bang.


Sound is greater when speed is slow.

It feels almost drivers seat. Feels very mechanic. Not just voice.


Forward/reverse no different.


What now? Something bad....

What about the transfer case shift motor. Sounds like that
