I have bought aftermarket ball joints but none have grease fittings can I tap grease fittings in them?

 

No. My advice would be return them and buy MOOG, a bit more but all have Zerg grease fittings and about the best on the market in suspension

 

Unless you're playing StarCraft, those are zerk fittings, not Zerg fittings.


I've done it on my old Explorer. I don't think I extended the life of those ball joints at all, though. If you bought cheap aftermarket joints they'll probably go sloppy before they go dry, I wouldn't bother adding a zerk.

 

I recently did my front end with moog parts. They are a little more expensive but worth it. If you can not buy them now, I would just put the parts you got as is. Tap them? Technically i guess you could. I wouldn't tap them. I don't think it would add much more life to them. Just my opinion. Post some pics if you do tap them and show us.

 

I'll put the aftermarket on my wife expedition since hers just has highway terrain tires. I'll buy some moog for mine since I'll have bigger mts on mine

 

good idea.
