hi new member here,a bit green with jimny,s having had a landrover previous.bought mine as its more economical but it came with a loud screeching noise which comes from i presume lower middle to front of the vehicle.the noise is not consistent,does not start for the first mile but kicks in inconsistently after.if i engage 4wd the noise is a lot worse after about 500yds as if its destroying itself.if i freewheel out of gear the noise is still there.also noticed the 4wd light on dash flashes while 4wd is engaged but i do not have a manual.i think it may be transfer box wheel bearings or diff/front, propshafts look ok,any ideas,p.s.what did you think of the off road show,i feel its turning landrover kap etc did not bother this year.
At first the description of screeching noise make me think alternator belt slipping. Then you seem convinced it is mechanical.
I wonder if the freewheeling hubs or at least one of them is partially engaged only. There must be a problem with them as the light flashes. The two parts of partially engaged hub may make the noise as metal grins against metal and will be made worse in 4wd as you try to put drive through them.
Just a thought but its hard to diagnose from here, where are you?

kirky thanks for your response though ive had a good 8yrs off roading i have no expereance with freewheeling hubs you may be correct with your diagnosis.how do they work on these jimnys,also it is not connected with the alternator belt,eagerly await your response,i am in the midlands by the way.
ok took off both hubs no noise,great replaced n/s only noise was back but not so loud,replaced o/s noise was louder but not as often.to sum up no noise without both but it returned with either on,could this be diff or hub
