So when I was younger, dumber and poorer. I bought a set of ball joints for my 87's D30 off of ebay. If my memory doesn't fail me, they were made in India.

Should I be worried about these ball joints (as in catastrophic failure) or will they just not last as long as quality ball joints? If so, I'll just change em the first sign of wear.

I do remember having to exchange one of them because it didn't press fit into the axle housing. It just kinda slip fitted in.

 

I wouldn't be concerned about sudden catastrophic failure. A lot of parts are from a lot of countries, quality is quality and junk is junk. If they were really cheap they'll just wear quick. Of course one can never know lol, keep 'em greased and check them every so often.
