Generally The layshaft The double row main and various other bearings. YOu may also need to replace gears if there are worn. Cheers Aaron |

Fit a competition diff pin and 2 new planet gears.. they don't last forever!  Rock the output shafts to and for to check wear, while looking at the pin & gears. You can do this looking into top of box while diff is in it.

Depends what the bearings etc are like. When I pulled mine out to change the cam, the gearbox cost me nearly $600 in parts alone. And I didn't need to do the 4 synchros, which are over $30 each now! 
Whatever, change all the needle bearings and check the layshaft, which is invariably stuffed. |

As I'm finding out at the moment some of those parts are not cheap. The double row main bearing was over $100,the lay shaft bearings will be around $50 and I know that I need at least one new diff bearing which I haven't priced yet. A new selector fork is horrendously expensive and for such a small item a diff competition pin isn't cheap. If you have the gearbox apart you might as well put a central oil pickup in ,another $80-$90. At least I had a good layshaft,gears and syncros.Still its a good learning experience and its one thing at a time at the moment. |

Look close at the layshaft, inside the 1st gear end of cluster gear. If it's wearing thru the hardening, bin it.

It's not the laygear you replace, but the layshaft. They are $50 -$90 depending where made and material spec. Dearer is better.
