where is the proper place to put the jack if im changing out the front tires? the back? if someone could illustrate that for me, i would greatly appreciate it!!

 

If you're talking about rotating the tires from the front to rear...I place the jack on the frame rail about mid way under the door and jack up the whole side and swap the front/rear wheels. Then do the same on the other side.

 

on lightning rodder there a thread with pictures
