Leaf springs on my 1500 GMC Savanna 4.3ltr V6 has apparently occurred. SAG truck appears in the back. I have many tools of FA on the back of my truck though. Sources who were once in the car. That worked well when it is sent, is everywhere, but a little leaked out. I had to at least once a week. I had this series, so that the rear leaf spring shackles were connected tore the fabric. (I do not know how it happened), when my friend accidentally pushed to burn a hole in the pipe for the air cushion of air, which they replaced with gas shocks. Now they feel very deeply in the back and I scratch my trailer ball in the world. (i tow a small trailer sometimes.) I wonder if there is a way to put the leaf springs stifferother truck, truck, or whatever. I do not want the new ones when I can do.
