Is this the same on the rear diff as that's what I'm talking aboutIf your going to replace it get a Robinson racing pinion some of the best on the market IMO
If your chewing up pinions check gear mesh and check your grub screws them backing of are number 1 cause of teeth were.
Both but mostly the rear, I would do that one first if you can only do 1 at a time. The front does flex and come apart but not as much as the rear.Are the aluminum gearboxes most beneficial on the rear (like the 3s line) or does the 6s line need them front and back?
Good catch. I didn't even think about that.So something I noticed in your post... You said you have now lost two input gears in a row.. I hope you mean input and crown?
If you put a new input (pinion) on an old crown (ring) it was over before it started.. always replace them in sets...
