If I'm going to use my truck for work, then I'd like to do some preventative work to it. However, a Google search didn't work and not trusting Ebay to be listing the correct parts for my truck.
For the most part, all I mainly need are seals and gaskets. (Lots of leaks, especially the trans.) It is easy to find them for the engine, but what about for medium duty transmissions and driveshaft/diffs? Most sites don't seem to go beyond 1-ton pickups. I would greatly appreciate it if anyone would point me to a webstore that deals in these AD medium duties.
