So after two hours on a brand new diff, they chipped again for the third time!!bad word After the second time I replaced the cups with Nova cups, I shimmed the unit so there was what I felt to be an extremely smooth mesh, used 10,000 weight silicone diff fluid, but they stripped again. None of the small bevels were damaged, just the large ones. So after some :thinking: about how things move inside the cup I'm leaning to believe that there can still be some shimming to be had but on the inside of the cup to raise the large bevel gear slightly to take up just a little more slop. After putting it together dry, it seemd to be even smoother than without the shim. The picture shows what I'm referring to, I put 1 BRP shim behind the pin. It effectively raised the bevel slightly to improve the mesh. My question is can someone tell me why this is a bad idea? I'm tired of going through bevel gear sets.
The truck is a stock X with the 4.1, running a 15T CB and a 47 spur. I am running 25% fuel too. Before it stripped, she ran like a monster so I'm curious if I need to change the CB to something a little taller to relieve some torque on the diff... Thoughts?
