Hi there my diff broke few days ago, I stripped it and found that my spider gears is broken, what's the best thing for me to do?

Get a new diff center. What kind of diff?

yeah a few more details.

 

the one time i stuffed a differential in my car, i just bought a complete differential and swapped it over.

 

i hate playing with differential oil.

Seeing as its already apart it'll be easier to just whack a new centre in though.

 

And yep, after doing my centre the other night I can totally agree about diff oil, especially old black stuff.

Diff oil is the most foul substance on the planet.

i got a diff :P 100 complete ?
