ball joints seat themselves?

sorry, i know this is in the wrong section, but i need an answer quick. i'm working on a large delivery truck and just replaced the lower ball joint. it gets pressed in from the bottom. i got it all the way in except for about 1/4-3/8" and was wondering if i had to get it completely in or if the weight of the vehicle back together would set it completely in while driving. if i had to do it myself, how would you recommend getting it completely on? thanks alot!

no, they are supposed to be totally seated upon installation. The best way is to get a large clamp with a hex-style handle (so you can use a socket on it) and push the ball joint in with it, using an impact wrench on the clamp.

thanks guys, didn't know about the balljoint press. got it as a loaner from autozone. worked perfectly!
