So I am an appliance Operator.. FJ40 Yes I have searched... How much 90 w will my 78 40 take in each diff? Why does my front diff have an allen wrench removal fitting and the rear a bolt / socket fitting? Sorry again, lovers of the flame but what size socket removes the Birf seal keeper, 54 mm? Anyone have an idea of how much a complete gasket and bearing set costs for one knuckle on a 40? Hugs and kisses everyone. JB AKA BigJim N6KML etc.
