I took Suzuki to court a few years back when my Jimny rear diff went bang for the second time under warranty, it ended up costing Suzuki about four times as much, insted of just fixing it..
Tell your mate to get a metalergy report done on the diff bits and dig up some specialist's then go to court and kick there arse again..
We kicked there arse , didn't we Mr Joe
And much Bourbon was had in cellibration...
