4wd transmission proplems, broke gearbox then diff and transferbox updated with broken gear selec Options

[tufy]

2 months ago i broke my gearbox, because i coulnt find stronger gearbox for daily use, i installed a 2nd hand standart gearbox which was slightly shorter... after i installed this g.box, traction of my car was more like front wheel drive.. (%60 front and % 40 rear. thats what i feel). then when i make a quick start i started to feel that rear diff. is slipping gears. after 3000 km i break my rear differential.
does anybody knows if ratio of g.box diff ratio and rear diffrential ratio change it make diff stress and broke easier. or my diff. broke from too much power.
simply;
does it make proplem in a 4wd car if i have shorter ratio gearbox without changing diff..
sorry for my bad english. and thanks for your help.

Tufy,

what did you broke exactly in the gearbox the first time ?

I found a good shop here in Italy, they told me they can make stronger helical synchronized gears for the E154 box... but I saw you already resolved with sqs ?
