i cant warn people enough about avoiding chinese/taiwan parts. ive heard of their hub assemblies failing at 30K. crankshafts in motorcycles dropping like flies. the list really goes on and on. poor machining, sloppy tolerances, cheap metals. from what ive seen on various websites, if it says made in taiwan that is a big warning label. my story is the same. bought a national oil seal for the trans. got home and noticed the box said made in taiwan. im regretting it now but i installed it. 1K miles later its leaking. probly some poor rubber material that isnt compatible with gear oil . nothing like doing the same job twice. hoping a local 4x4 shop can get me a high qaulity seal. skf or something like that

 

Good advice.
Too bad some "Made in USA" isn't all you think it is. A lot of times it is assembled in USA parts are made in China ect.
