Problème avec le differentiel

[Adacfi]

(mes excuses pour l'anglais, mais je ne peux pas l'expliquer en français...)

For the 3d time in 3 months I have a broken front differentiel... (no, it's not that I can't use the 4x4)

It's an Frontera Sport 2.0i, with 33-ers Maxxis Mudzilla. Some of my friends blame it on 'an Opel is no 4x4', or 'an Opel is not made to go offroad...'

But I think, the 33 is to heavy for the diff.

Now my questions:
1) Anyone experienced the same probs with the front diff?
2) Alternatives for a stronger diff?

Hi,
I don't understand why you "speak" us in english but i will try to answer you:
The front differentiel of the short Frontera is not enough "strong" for big utilisation off-road because it have only 2 "satellites" (the long Frontera have an differentiel with 4 "satellites).
So with your modifications (body-lift, wheels...) the powers are "too much" at every turn of the wheels for the differentiel...
Y can propose you just one solution: to change the "rapport" (in french) of your front axle.
Look there, if you speak american i'll think you will find all you want here:

Hi
My english is not enough technical, but i think you can find informations reading all article about axles (tera low gears for example)

The tera low gears will change the power on the transmission, and will increase power on the diff, I think.

(plus de force sur le transmission, ET plus de force sur le diff)

Can anyone confirm this?

Can I use a diff from eg the 2.3 TD or the 3.2 V6? Do these have the same 4.88-transmission, AND are they stronger?
