I noticed a popping sound from the back of the truck, when going around corners. After doing some research, I concluded that the leaf spring bushings were shot, causing the pop. So I ordered a set bushings from rockauto.com, and watched a few videos on YouTube for practice, lol, and hit the bolts up with PB Blaster. When the bushings came, i got the truck up on jack stands and pulled the wheels. The truck has to be lifted by the frame, until the wheel comes off the ground, fyi. The old bushings came out fairly easy. But i had to really fight to get the new ones in.
I ended up using a large C-clamp to squees the shackle and bushing through the holes.
And a little Gold spray paint later
That as far as i got. I still have to do the front. Its gonna be a real PITA. But i saw a vdo on YouTube where a guy used a screw jack shaft, or something, but it gave me an idea of maybe using threaded rod the same way.
