Ball joint question

[wild stroker]

Hello guys. How long are your ball joints lasting in the 03 6.0L front end? I have a buddy who has an 03 6.0L with 50,000 miles and his ball joints are already shot. I was just curious what you guys have experienced. It seems that the ball joints should last longer than that. Just wondering your thoughts.

Depending on the driving conditions, but I am hearing 60k to 70k life on average. Then change them out w/ aftermarket greasable ball joints - like MOOG.

I had all mine done by ford under extended warranty at 63,000

whats a symptom of a failing joint?

Thanks for the quick replies. Ya I think my buddy is going to have ford replace the ball joints under warranty. Do the greaseable ball joints usually last longer?

I seen most factory joints only last 30 to 40,000 miles. The factory ones are not greeseable and with all that weight of the diesel on them they don't last

[Dusty's Diesel]

Greese them every oil change top and bootom. Yes they last alot longer if they have been greesed

I had to customize my top greese zirk with a grinder so i could get it theaded in but now it works great.

Make sure they give him both the top and bottom greesable. My o1 only had greeseable joints on the bottom, and you had to screw the zirk in and greese it and then take it out and put a plugg in it because the zirk hung really low. but on my 04 i leave both top and bottom zirk in all the time.
