Well im having a good average this year, 2 motorkhanas 2 broken diffs!!!

Why is it so hard to get some decent diff components these days, even the competition diff pins are made of blu tak & the sun gears are made of rice crackers, looks like another cross pin diff is needed for my Cooper S.

With all the "technology" we have these days, how hard can it be to get good stuff, they could make good strong stuff in the 60's, why not now????

Because now the Chinese make all the steel, but no-one taught them how

Ring Heritage MG, they make their own layshafts here from real steel, heat treated properly, maybe they do diff pins too.

GR said he was going to make some up out of the chrome moly he had lying around & get them hardened, we can only hope they come through!!!!

I have heard it stated by others that the competition diff pins sold these days are inferior to the Rover std ones. But I guess these are probably NLA now, like the Rover spider gears..

Go to a company that makes springs and get a piece of normalised spring steel round bar. After machining then get it heat treated. Chrome moly will remain brittle after heat treating, and will not take the shock loads like spring steel.
The problem is to get a piece of steel that is hard for wearing but is not brittle to stress. Look at a bearing, hard wearing but brittle.

Would be nice if you could give us a book summary in English, Klas.
Please?

Just buy a Quaife Planetary type diff & be done with it

I even bought a planetary type limited slip for my Kombi

You should put your heart & soul into everything you do.

i will try, but give me a day to read it again and find the right words.

IIRC there was no big difference (but it was 2003, so i might be wrong)
