Are these the same as oem? Cause my oem have worn out fast...
Out of curiosity, what are the signs of worn ball joints? I plan on replacing mine but would love to know when that time has come before some type of catastrophic failure (assuming they can "catastrophically fail").

Excessive movement.

To test jack up the jeep and put a jack stand under the front axle, take a long bar or broomstick and use it as leverage to push up on the front tire and let it drop, as you do this get a friend to help, look at the lower ball joint and see if it has excessive vertical movement, I believe .05" of movement is within spec.

For the upper ball joints have a buddy grab the tire (still while on the jack stand) at the 12 o'clock and 6 o'clock position and shake it back and forth, look for excessive lateral movement in the upper ball joint, I believe .06" is within spec
