help !! any other way to fill gearbox oil

Hi its the first service on my jimny and ive drained the gearbox oil but when ive come to fill it the fill/level bung is totaly rounded off . Is there any other way to fill it? and how much should i put in . want to be out tomoz and dont want to take box out if poss . thanks

I've done this before and as a temporary but tedious alternative i filled it via the breather. It took longer obviously but i just hung the bottle upside town with a pipe going into the breather and left it. Did the recommended oil amount. Can't remember exactly how much it is. But it's a way around it until you can get that bung out

Life lesson learned here on anything ALLWAYS UNDO THE FILLER FIRST dont know if you can fill through were the lever is you can on a transferbox

Cheers dude . I welded a nut to it and got it out . Thanks anyway mate

Nope, definitely can't fill through the gear stick, it's a remote linkage.

What a life saver, on post 2005 Jimmy's the breather is easily accessible from the bay and with a massive suction syring an length of pipe managed to refill the box easily.
Wish I saw this earlier, struggled for 2 hours trying to remove a damd rounded filler plug...
Thanks.

Was you using the proper square socket

No 3/8th ratchet, what's weird is its come undone before for a level check, this time it was warm after a run so I'm guessing it got tighter when hot? Maybey the plug expanded more than the metal around it? Who knows...

Yes could have done it’s worth getting a proper set of drain plug keys they fit tighter think it’s a 10mm I tried to undo drain plug on axles with ratchet but would not shift soon as I put a 10mm plug key on it undid straight away
