Anyone experienced with LSD diffs?

[filh]

I had lot of trouble with stock LSD. I broke 4 on my rally car( happend very often in rallies with jumps !!) Inside the LSD ? There are discs of course but two major parts called clutch member (lh rh)THese parts are very often broken ( broke 4 ) It's impossible to buy these parts at Toyota as they're out of prices . About 1100€!!!!!.
If these part are in a good shape , don't forget to check the 4 member clutch springs (located on the part i've mentioned above). They are often weak and you 'll be better to change them. I do something to get them harder : fit 1 or 2 washer ( 3 or 4 mm thin).it's a litle improvment on lsd efficiency.ALso did very thin disc by myself(0,5mm) and fitted one on each end of lsd(same shape as last disc) it will get more efficiency too. it's a cheap way to reinforce that part as long as the disc are not completly burned.
Have a nice job and good luck.
