Better diffs for the 3905

[Janezki]

Yes, I have run the truck with this setup. Even had a spool in the rear, but that seemed to be a bad idea...







And all of the above only with 4S and on snow.

Few teeth were also chipped from the ring gear, so I swapped the front diff (which was as new) to rear and vice versa.

The 3905 diffs are supposed to be quite a bit stronger than those with the 3906, so maybe I'll just order new pinion/ring gear set for the other diff and wait and see how much the stock diffs can handle.

For the moment only real problem are the center driveshafts - broke two of the fronts only today...
They are out of stock from almost everwhere I have looked, but fortunately one can be made out of a 3.3 plastic driveshaft.

I've seen Kershaw Designs is making steel shafts, but the company is not known to me.
The price isn't too bad, dunno about shipping to Scandinavia though.
