I plan on fixing this before anymore driving. I found some numbers on the ring gear. 1813637 10-39 GM 81
Whats your input do you think the is the original internals to this truck? It really looks like the housing was ground out a bit at one time to fit this ring gear.
Im defiantly thinking my problem lies with a bearing. Just curious on these numbers on ring gear and if they match up to a original rear.
