iff i take the diff from the legacy, what about the rear axels.

what problems can i aspect with the front axel,s

thanks oldskoolscooby from the netherlands

So long as the diff that is currently in the Subi matches the new gearbox ratio then just leave it as is .

I'm not sure exactly which 4WD box you mean, I'm assuming you mean the box that matches the engine.

If the diff from the L1 is the same ratio as the legacy then you can just stick with the L1 diff, if they're different then you can take the crown cog out of the legacy diff and fit it to the L1 diff, that way the ratios will match and you can still use the stock axles.

BUT if the legacy diff is an LSD then you'd be better of swapping the whole centre into the L1 casing.

As far as the front axles you can put L series stub axles into the EJ box and just use the standard axles or put the EJ bearing cups onto 2WD MY shafts.


Hope that helps.
