Ball Joints-

[99xj4x4]

I cannot for the life of me keep ball joints in my D-30 that is spinning 35s. Ive replaced 4 in the last year. I fully understand this is one of the weak spots in a d-30, but come on. I buy the better ones that Crown sells ($80). Ive personally installed them and had my buddy who is ASE and has 40+ years of jeep/automotive experience install them, so that leaves any install errors out. I grease the hell out of them all the time. My last ball joint lasted a whole month (I did get it warranted from Crown)! The lower joint was so bad when I replaced it the ball bearing fell out and the joint was in 2 pieces.
Am I just overly had on them, or what? What brands you recommend running as a replacement? Are there any really heavy duty ball joints on the market?

Welcome to Dana 30 with big tires ville.

I replace my ball joints every 6 months. I beat the ever living piss out of my jeep. I have Vatozone lifetime warranty ones, and I can usually swap both sides out in about an hour.

Anywho, if your caster angles are off, it could lead to premature failure.

Caster is right where Ive always run it at just a tad over 6 deg.

Hahah Vatozone!

1st. umm if you keep haveing issues with them and you have always had the castor at the same angle..then you might wanna change something!!
