Anyone having Savage diff problems?

[jhautz]

Thats a great tip on the difs. I like it. Cheap and effective. Do you know the gear ratio on the CEN difs? I know they use some funky tooth counts in their buggy and truggy. The Buggy is something like a 9T pinion and 26T ring gear. Are these the same gears? If so I have a couple of those diffs sitting here in my CEN parts bin as spares from my buggy tht I never needed. If they are the same, I might just do this mod. I think the CEN buggy difs are Mod1.5 gears rather than the standard mod1.

I had issues with my Savage X difs at first. I had the plastic cups from the box, I kept cracking the cup not breaking the gears. After tearing up a few sets of those rather quickly I upgraded to the aluminum cup in the rear and shimmed it up properly and I never had another issue. The front dif is still the stocker wth the plastic cup and I never had an issue so its still running. I have the aluminum cup for it sitting here in a box along with a full set of gears and pinion for it but I am not going to replace it untill it breaks. I also bought aluminum bulk/gearbox for the rear but again I have been waiting to see if I needed it before installing it. I didnt want to just fill the truck with aluminum just for the hell of it. And so far I havent needed it.
Of course I'm not running a 1521 either. Just a little 1940.
