Driving in 4 wheel drive on road!!

Hi all I have had many jimnys over the years however none with a rocklobster box.
However....I didnt realise I had it in 4 wheel drive when driving on the road for a fair few miles as I wasnt familiar with the gear positions I also had hubs locked in .
will I have damage any running gear ? If so what's usually first thing to go ?it does seem to have a click / clunck when setting off from the rear ((

This set-up can be very damaging, the extent depends on a number of factors.
1) The closer the tyres are to having similar diameters is good as it will reduce axle wind up.
2) The looser the road surface is good as it will promote wheel spin which will eliminate, at least partially, axle wind up.
As you don't mention rough running or a gradual slowing down, then you may be in luck but I don't like the click/clunk from the rear. Is this noise new or was it always there?
As to what goes first, it depends on the condition of lots of things from the T/box onwards.

So stripped it down today halfshaft look ok however rear prop uj has shot needle bearings out so I will replace them and hopefully that's that sorted .
Can anyone confirm if a QL102 universal joint will fit ? Measurements are correct
QL15002 is same measurements however it's a sealed unit .
Thanks Sam

   

lt's not a good thing to do in a Jimny for the reasons mentioned already.

However if everything else on the transmission is still working on the vehicle apart from that universal joint, you most likely got away with it.

Change to 2wd and carry on.
