So took my truck to Toyota today and told them whenever i had a few hundred pounds of load in the back of the truck, it would bottom the rear out and have a harsh ride to it. I printed out the Rear Harsh Ride form from the company and took it to them and they said not a problem they would order the parts.
The mechanic told me according to the form, basically to fix the harsh ride the only thing they would do is loosen up the rear springs which would soften up the ride but when i have a load in it the rear is going to bottom out. He said he didn't know what would come in with the order to fix it but thats more then likely what they would do.
I even played on dumb like well the way Toyota talked where the rear has 3 leafs to fix the harsh ride when loaded, they would simply put another leaf spring on there.. I mean really if it is bottoming out when i have a load in the bed (which is what i told him) why in the world would they loosen the springs to make it bottom out anymore?
