Please note that spinning the wheels in the snow or on any slick surface and contribute to breaking the pin or making the diff pin come out.Ĭase had some rub marks from “stuff” hitting it but it was ok and we reused it see pics below. It was pretty amazing to find it this bad. Here’s another one that broke the rolled pin. Sometimes the cause is the rolled pin breaks and allows the pin to come out. After pulling out the trans we found this hole. Sometimes it moves out and breaks the case. When the Pin that the spider gears spin on comes out the pin moves outwards and rubs the case until the case wears a hole in it. I only saved a picture of the race though. The other pinion bearing had some minor wear.

We can install replacement case when necessary. I would have loved to weld up the hole and replace the bearings, but the race had spun in the case and didn’t fit tightly, so the case half had to be changed. This used to be the lower pinion bearing. This one made a bunch of noise and when we pulled it out we found more damage than we were expecting. We were able to fix this one with just some bearings. It will usually whine on acceleration and quiet down when coasting.Īnd the following pic is the worn bearing race. When the bearings fail on the differential or on the pinion it makes a whine noise.
