Magnum reseal questions?..

I bought it from a silver spoon kid who only had it for 6 months and his father had the transmission rebuilt the whole rear axle and brakes and everything rebuilt and they bought it with 116, 000 and I bought it with a hundred and twenty four thousand with 8 months still left on the transmission warranty at the time a little over a year ago.. It seems like everything I'm replacing is all Factory original...
