One over looked area to be cleaned is at the end of the axil where it goes together with the king pin. If you look in the back of the spindle part you see a hole or cavity that gets full of hard grease and dirt. Take something and knock out this junk as it causes the truck not to turn as sharp by binding up the axil end and the spindle part. This area is a couple of inches deep.Youll be surprized at how much stuff is in there.
