I do not know what modifications I could’ve made to allow this pump to be installed in the transfer case for me it did not fit. I think the engineers need to go back and rethink this product.

I enjoyed taking my transfer case, apart and learning how to rebuild it and install this piece inside. It took patience and time to understand but I am grateful I made the choice to purchase this product for my GMC Yukon. (2007)
