I am getting ready to order some heim joints for my front axle tie rod ends on my 149 and super axle. I was looking at Mcmaster and they offer several different styles such as steel, high strength steel, bronze insert, some with teflon inserts for the ball and some with grease fittings. It's to much to choose from
The cheapest are the plain steel with either the teflon insert or grease fitting.
I would imagine you wouldn't want grease in them to catch all of the dirt
The bronze bushing ones are just a little more. What have any of you used?
