What's the general consensus on the ball joint, replace or rebuild. The manual says replace if the dust cover is damaged, however the dust covers are still available from Nissan. The specs for testing the ball joint are also in the service manual.

I've managed to disassemble, clean and rebuild my original ball joints, any reason for not using them with a new dust cover and fresh grease?

Aside from replacing a part that meets Nissan specs, another factor to consider might be that used Nissan is probably better than new aftermarket.

If there is more than 1 mm of play in the balljoints i would replace them, i believe nissan still have them? just look up the last part number and the dealer has the orig. part.. (If the balljoint comes apart.. someones life ends, would you take that risk?)

I have no idea what you are talking about, there is no way the ball joint can come apart, it is a enclosed joint. The nut would have to shear off the shaft but even then there would be no catastrophic failure. How can you say someone's life ends if this happens? My question was if I should keep using the original balljoint if it meets all of Nissan's tolerances as @Zed Head said.
