    I assume this is just a dressed up JK, but it’s a pretty cool design.

    How thick is a C tire carcass?

    How thick is the carcass on a C rated tire? I just pulled a piece of broken tail light out from between some treads and it was in there about 1/4”. No leaks obviously, but just wondering if that spot will be weak going forward.

    Should I replace NP231 oil pump during rebuild?

    Should the oil pump be replaced during the rebuild or is that not much of a concern. I’ve got 146k miles on it and only rebuilding because the transmission is out for a rebuild.
