I got the truck off the stands tonight and got the old dually wheels put back on so I could test my rear suspension movement.
I have heard a lot of trucks over the years squeak and groan going through their full up and down movement, which tells you that there is something binding up somewhere in the suspension system. I made sure the shop was very quiet to take this video because I wanted to hear if anything was binding up, and I was glad to see that it went through the whole movement without making even a squeak!
I made up a rig for the air bags with a ball valve on the end. Thanks again Home Depot!!!
Any way check out the video I put on YouTube and let me know what you think.
