Hi all i know its not a four wheel drive but it gets me around albeit a bit more cheaper and reliable now my question is oil what oil should i be putting in the diff as after 140 000k she is black and dirty. Ford dont sell the oil but the service department can change the oil for a fee.
Regards
Steve

unless the lsd in the falcy is as durable as that in a Patrol, I would be surprised if you don't need a complete diff service after that many kays and given the "quality" of the oil - e.g. replace clutch packs (if it has them) etc. One way to check this is to jack one rear wheel off ground to see how freely you can spin it. A really strong lsd should be able to drive over a brick with the other rear off the ground (i.e. even though one wheel is "slipping" the other wheel should still be getting some drive to it. If you decide to just change the oil, any hypo lsd oil should do...

Gday Steve
Im only guessing, but if you have a Hydraulic or viscous diff, as in the longreach uterus,the oil in the viscous part is not replaceable (sealed unit) and the oil in the diff should be std gear oil.
What sayeth the owners manual?/workshop manual/ ever thought about the reference library to have a look?

Penrite Limslip 90/140 available Autobarn etc. You hassle will be getting the oil into the housing, unless you can borrow a pump.
