Cheers buddy, bought it ages ago but read elsewhere I needed GL5 and that GL4 was only for the gearbox

It should be GL5 for the axles.

There are less anti-wear additives in gl4, but likely you won't notice any difference, get GL5 next time.

75/90 gl4 in the gearbox, those extra additives can damage the yellow metals used for synchronisers and bushes in a gearbox.

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

Hmmm reckon I should just change it before I do the job? High mileage car so should have the proper stuff really

If it was me, I'd stick that in the front diff, as I don't use 4wd much, and get a couple of cans of GL5 for the rear one that turns all the time.

(If you can swap it for GL5, do- BTW you need 3 bottles to change front & rear diff oils, the rear holds just enough so there isn't quite enough left in the second bottle for the front :pinch: )
