Hi , has anyone had problems with the 80 series front diffs on the gxl petrol models, and does anyone have a manual on rebuilding them

It is common for the c/v joints to wear out on the constants, which click under hard turning, more noise than actual problems, but they then start to leak diff oil and rego doesnt like that.
The diff centre doesnt like high torque in reverse, and the gears sometimes smash...dont snatch with an 80 or 100 in reverse.

Ok,
I think the most probable reason for this is the drive plates...they wear the splines and then they start spinning in them.
Take the dust caps off the axles each drive plate, and unlock the ctr diff.
You will soon see if one is stripped out.
if ok, drain the diff oil and see if chunkies come out.

ps drive plates are where a free wheeling hub usually goes.

ok , ive unbolted diff centre and removed front tail shaft so i can get a bit of a look at the centre , chunks in the oil, this is how i saw the crown wheel missing the teeth , i put it down to wearin the pinion shaft maybe letting it move, but when i pull the axles out i guess i will know , either rebuild it or look for a good second hand one as the reco ones are pricey , had to replace rear centre on myother fourby ,( bunderra) , cost me a squillion
